Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority from U.S. provisional
application No. 62/281,136, filed Jan. 20, 2016, and from U.S.
provisional application No. 62/404,125, filed Oct. 4, 2016, the
contents of each of which are incorporated by reference in their
entirety.
TECHNICAL FIELD
[0002] The present disclosure relates generally to exercise
equipment.
BACKGROUND
[0003] Currently, 90% of American's do not regularly strength
train. Part of the reason includes the lack of devices that are
convenient to use and accomplish maximum results in the least
amount of time. The permanent, gradual muscle loss starting at age
25 has resulted in a new area of medicine referred to as
sarcopenia. In addition, the cost due to lower back pain has
doubled in the last 20 years from $50 billion to over $100 billion
in the United States alone. This level is expected to exceed $220
billion by 2025.
[0004] One of the causes of lower back pain is weak and permanent
loss of core muscles. Many home and professional exercise machines
focus on only a single muscle group at once, which lack the ability
to isolate and strengthen multiple interconnected muscles. Many of
these machines require significant time at the gym and have the
potential to increase the risk of muscle injury. Many of these
machines also lack convenience and portability.
SUMMARY
[0005] There is a need for exercise devices that can simultaneously
exercise multiple core muscle groups, often within only 3-5
minutes. As an exemplary advantage, such a device could combine
multiple mechanical power units and simultaneously coordinate
multiple biomechanical movements or multiple anatomical muscle
groups. Such a device would simultaneously contract or strengthen
all core upper and lower muscle in a fluid harmony. Simultaneous
exercise can require the user to produce more total effort and
energy as the user coordinates the movement of multiple muscle
groups compared to working out each muscle group alone. Exercising
multiple muscles simultaneously builds muscle strength more
effectively, improves flexibility, reduces the time needed to
achieve results, decreases the risk of potential injury, and
alleviates back pain.
[0006] In some embodiments, provided herein is an exercise
apparatus includes a first thigh member and a second thigh member
moving in a first reciprocal motion when the user engages the first
and second thigh members, the first reciprocal motion varying, or
adapted to vary, a first distance between the first and second
thigh members, and a chest contact member moving, or adapted to
move, in a second reciprocal motion when a user engages the chest
contact member, the second reciprocal motion varying, or adapted to
vary, a second distance between the chest contact member and the
first and second thigh members. In some embodiments, simultaneously
varying the first distance and second distance can compound the
exercise benefits of varying the first distance and the second
distance sequentially or separately. In some embodiments,
simultaneously varying the first distance and second distance can
require the user to produce more total effort and energy as the
user coordinates the movement of multiple muscle groups compared to
working out each muscle group alone. In some embodiments,
simultaneously varying the first distance and second distance can
build more strength and burn more calories than sequential or
separate motion.
[0007] In some embodiments, the exercise apparatus further includes
a first resistance member, wherein the first resistance member
provides, or is adapted to provide, a restoring force on the first
thigh member relative to the second thigh member when the first
distance decreases. In some embodiments, a maximum distance between
the first and second thigh members is adjustable.
[0008] In some embodiments, the first reciprocal motion includes
both the first thigh member and the second thigh member moving, or
adapted to move, relative to a centerline of the exercise
apparatus. In some embodiments, the exercise apparatus further
includes a second resistance member, wherein the second resistance
member provides, or is adapted to provide, a restoring force on the
chest contact member when the second distance decreases.
[0009] In some embodiments, the exercise apparatus further includes
an abdominal contact member moving, or adapted to move, in a third
reciprocal motion when the user engages the abdominal contact
member, the third reciprocal motion varying, or adapted to vary, a
third distance between the abdominal contact member and the first
and second thigh members. In some embodiments, the apparatus
further includes an abdominal crunch base guiding, or adapted to
guide, the abdominal contact member when a user engages the
abdominal contact member and moves it in the third reciprocal
motion. In some embodiments, the exercise apparatus further
includes a third resistance member, wherein the third resistance
member provides, or is adapted to provide, a restoring force on the
abdominal contact member when the third distance decreases.
[0010] In some embodiments, the first and second thigh members are
configured to move in a fourth reciprocal motion when the user
engages the first and second thigh members, the fourth reciprocal
motion varying, or adapted to vary, a fourth distance between the
first and second thigh members and the chest contact member. In
some embodiments, the exercise apparatus further includes a fourth
resistance member, wherein the fourth resistance member provides,
or is adapted to provide, a restoring force on the one or more of
the first and second thigh members relative to the chest contact
member when the fourth distance decreases.
[0011] In some embodiments, the restoring force of one or more of
the resistance members is adjustable. In some embodiments, one or
more of the resistance members are interchangeable with other
resistance members.
[0012] In some embodiments, the exercise apparatus further includes
one or more handles. In some embodiments, one or more of the back,

DETAILED DESCRIPTION
[0072] Machines and devices can make exercise and rehabilitation of
an illness or injury more effective and more efficient. Such
devices can precisely isolate specific muscle groups during a
workout, improve a user's form, and provide additional
resistance.
[0073] In the following description of preferred embodiments,
reference is made to the accompanying drawings which form a part
hereof, and in which it is shown by way of illustration specific
embodiments in which the invention can be practiced. It is to be
understood that other embodiments can be used and structural
changes can be made without departing from the scope of the
embodiments of this invention. Any of the embodiments described
above or in the following can be combined with one or more
embodiments and/or with one or more elements from one or more
embodiments.
[0074] Some embodiments of the devices and methods disclosed herein
involve combining four different exercises: 1) thigh adduction, 2)
lateral resistance pulls; 3) direct resistance to the front
abdominals comparable to doing crunches slowly with a weighted
medicine ball; and 4) a decline bench crunch. Some embodiments of
the devices and methods disclosed herein involve combining the
following four different exercises: 1) thigh abduction, 2) lateral
resistance pulls; 3) direct resistance to the front abdominals
comparable to doing crunches slowly with a weighted medicine ball;
and 4) a decline bench crunch. The exercises can be completed
simultaneously in a coordinated and fluid manner. In some
embodiments, the resistance the device supplies for each exercise
is individually adjustable to suit the user.
[0075] As an exemplary advantage, the devices and methods described
herein can simultaneously exercise multiple core muscle groups,
thus increasing workout efficiency, building muscle strength, and
improving flexibility.
[0076] Currently, there are no exercise devices that simultaneously
contract all core muscles and the thigh adductors. A strong core
can be the foundation to a better, healthier body. The core
provides the foundation for virtually all muscle movement. The
upper core includes all the muscles of the midsection and hips that
support the spine, back, and neck, while the lower core includes
the hip connection and glutes. Developing a strong core, including
strong abdominal muscles, can help prevent back injury and pain by
improving posture and spinal alignment, alleviate the amount of
work other muscle groups must do to bear the weight of the entire
body, and improve balance and stability.
[0077] The same is true of adductor muscles. The adductor muscles
work in concert with the abdomen, back, and shoulder muscles to
stabilize the torso. Weak adductor muscles can increase the chances
of knee, ankle, and foot injuries. Simultaneously exercising the
core and adductor muscles means that these muscles are working
together as they do in normal, natural motion.
[0078] Working out core and hip adductor muscle groups
simultaneously has the added benefit of compounding the effects of
each individual exercise. Simultaneous exercise can require the
user to produce more total effort and energy as the user
coordinates the movement of multiple muscle groups compared to
working out each muscle group alone. A user exercising both core
and adductor muscles can overcome a greater total opposing force
and burn more calories than exercising the groups individually.
This can increase the total intensity of a workout and build
stronger muscles with greater efficiency.
[0079] For example, a user exercising multiple muscle groups
simultaneously can use more weight or resistance and burn more
calories than working out a single muscle group in isolation.
Working out core muscles separately can significantly reduce the
intensity of the contractions and resistance compared to multiple
simultaneous contractions. Typically, greater levels of core muscle
contraction lead to increased fast twitch muscle fiber recruitment.
This is why more resistance, less repetitions and slower anaerobic
movements can be more conducive to strengthening the core muscles.
Many abdominal/back machines incorporate fast movements resulting
in very little strengthening of the abdominal/back fast twitch
fiber muscles. As a result, an individual could be better off doing
eighteen crunches slowly with a 30-pound medicine ball, as opposed
to 300 crunches fast.
[0080] Building muscle strength typically requires a person to
frequently and consistently exercise the same muscles over and
over. Given how busy people are, the compounding effects of
simultaneous exercise become increasingly important. Machines that
isolate individual muscle groups do not allow people to maximize
their workout of each muscle group. Machines that isolate
individual muscle groups also do not allow people return to each
muscle group often enough to see gains in muscle size. Exercising
multiple muscle groups at once allows a user to exercise more
muscle groups more often, and therefore see a resulting gain in
total muscle size and strength.
[0081] Another exemplary advantage includes focusing on multiple
muscle groups simultaneously, thereby reducing the amount of time a
person needs to complete a full-body exercise routine. This allows
a person to exercise more muscle groups in the same limited period
of time.
[0082] As another exemplary advantage, the devices and methods
described herein assist a user in completing the exercises with
proper posture and body position. Proper posture and alignment can
be important in preventing injury and maximizing a workout. As
another exemplary advantage, a user can perform the exercises
described herein in a variety of orientations, including while
seated or supine. As another exemplary advantage, the systems and
methods described herein allow a user to mimic the mechanics of the
traditional exercises described above while adding external
resistance.
[0083] Another exemplary advantage includes the ability to perform
exercises at varying speeds and with varying levels of resistance.
Certain exercises may be more effective when performed in slow,
controlled motions or when performed in rapid bursts. As previously
discussed, greater levels of core muscle contraction lead to
increased fast twitch muscle fiber recruitment. Thus, more
resistance, fewer repetitions and slower anaerobic movements can be
more conducive to strengthening the core muscles. In some
embodiments, the devices and methods disclosed herein incorporate
slow movements resulting in greater strengthening of the abdominal
or back fast twitch fiber muscles. As a result, an individual could
be better off doing a few repetitions slowly using the devices and
methods described herein than doing a large number of unassisted
crunches quickly.
[0084] Because the devices and methods described herein provide an
efficient workout, a user can frequently and consistently return to
exercising the same muscle groups often enough in subsequent
workouts to increase muscle size.
[0085] FIG. 1A represents an isometric view of an exemplary
exercise apparatus 100 in accordance with an embodiment. FIGS. 1B,
1C, and 1D represent front, side, and top views of apparatus 100,
respectively. Apparatus 100 allows a user to perform a thigh
adduction exercise while simultaneously contracting many or all
twenty-four segmented abdominal muscles (within the rectus, oblique
and serratus groups), lats and back flexox muscles. These muscles
collectively constitute the core muscle groups. The exercise
apparatus 100 can include a first thigh member 102a and a second
thigh member 102b and a chest contact member 101. As will be
described, the first thigh member 102a and second thigh member 102b
can help a user perform a thigh adduction exercise. The chest
contact member 101 can allow the user perform an exercise
equivalent to a decline crunch. In some embodiments, the chest
contact member 101 is coupled to a chest crunch base 103.
[0086] Apparatus 100 optionally includes an abdominal crunch
contact member 110, which can provide direct resistance to the
front abdominals comparable to doing crunches slowly with a
weighted medicine ball resting on the abdomen.
[0087] The adductor muscles exercised can include the adductor
brevis, adductor longus and adductor magnus, for example.
Exercising these muscles can include a user starting with his or
her thighs spaced apart, contracting his or her thighs towards a
midline of the user's body, and then releasing the adductor muscles
to return the thighs to the starting position. Thus, in some
embodiments, apparatus 100 assists in exercising thigh adductor
muscles by providing additional resistance during thigh
adduction.
[0088] The first thigh member 102a can be connected to the second
thigh member 102b such that the first and second thigh members are
configured to move in a reciprocal motion. The reciprocal motion
can include varying a distance between the first thigh member 102a
and second thigh member 102b, or can include being adapted to vary
a distance between the first thigh member 102a and second thigh
member 102b.
[0089] In some embodiments, the exercise apparatus contains a
resistance member that is configured to provide a restoring force
on the first thigh member 102a relative to the second thigh member
102b when the distance between the first and second thigh members
decreases. In some embodiments, a maximum distance between 102a and
102b is 16 inches, as measured from a point on 102a that is closest
to a point on 102b. In some embodiments, the maximum distance is 15
inches, 14 inches, or 13 inches. In some embodiments, the maximum
distance between 102a and 102b is configured such that the maximum
distance between a user's knees while still in contact with thigh
members 102a and 102b is between 14 and 24 inches, including 23
inches, 22 inches, 21 inches, 20 inches, 19 inches, 18 inches, 17
inches, 16 inches, and 15 inches. In some embodiments, the maximum
and or minimum distance between the first thigh member 102a and
second thigh member 102b is adjustable. Thus, in some embodiments
the device can accommodate multiple users of various sizes or
multiple thigh adduction exercises. For example, the user can
choose between short, quick movements with a smaller maximum
distance between the first thigh member 102a and second thigh
member 102b, or slower, longer movements across a wider range of
motion.
[0090] In some embodiments, the device is configured to exercise a
user's abductor muscles. As will be apparent to a person of
ordinary skill in the art, the first thigh member 102a and second
thigh member 102b can be configured to engage the outside of a
user's thighs while moving in a reciprocal motion. The reciprocal
motion can include varying a distance between the first thigh
member 102a and second thigh member 102b, or can include being
adapted to vary a distance between the first thigh member 102a and
second thigh member 102b. In some embodiments, the exercise
apparatus contains a resistance member that is configured to
provide a restoring force on the first thigh member 102a relative
to the second thigh member 102b when the distance between the first
and second thigh members increases.
[0091] In some embodiments, the position of the first thigh member
102a and second thigh member 102b are fixed. In some embodiments,
the first thigh member 102a and second thigh member 102b can rotate
about an axis such that the thigh members can be configured or
positioned to engage the inside or outside of a user's thighs
depending upon the position of the thigh members, or at any angle
in between that accommodates a user's thighs. In some embodiments,
the thigh members include a locking mechanism to secure the thigh
members in place.
[0092] In some embodiments, both the first thigh member 102a and
second thigh member 102b move in a reciprocal motion relative to a
fixed point, such as a centerline of apparatus 100. In some
embodiments, a centerline of apparatus 100 can be understood to be
a line between the first thigh member and second thigh member,
whether equidistant from the first thigh member and second thigh
member, or not. In some embodiments, a centerline of apparatus 100
can be understood to be an element of apparatus 100 between the
first thigh member and second thigh member, such as abdominal
crunch base 104 (described more fully below).
[0093] In some embodiments, the first thigh member 102a and second
thigh member 102b are attached to a thigh base 112. Therefore, in
some embodiments, both the first thigh member 102a and second thigh
member 102b can move relative to a point fixed at the center of the
thigh base 112. In some embodiments, one of the first thigh member
102a or second thigh member 102b is fixed at a set distance from
the fixed point, and the other of the first thigh member 102a or
second thigh member 102b moves relative to the fixed point. In some
embodiments, one of the first thigh member 102a or second thigh
member 102b is in a fixed position on the thigh base 112, while the
other of the first thigh member 102a or second thigh member 102b
slides along the thigh base 112 in a reciprocal motion relative to
the fixed thigh member or the centerline of apparatus 100.
[0094] In some embodiments, the first and second thigh members 102a
and 102b, respectively, are contoured to receive and engage a
user's thighs. The thigh members can have a concave shape or a "C"
or "U" shape. The shape can be designed with a radius of curvature
to more closely contour to the shape of the human thigh. The
curvature can allow a user's thighs to nest within the thigh member
in a manner that increases the surface area of the thigh member
contacting the user's thighs. Increasing the contact area can
increase a user's comfort. The size of the thigh members can also
vary to increase the amount of surface area in contact with a
user's thighs. In some embodiments, the thigh members have a wide
contact area to distribute the force of the exercise across a
larger part of the user's thighs. The thigh members 102a and 102b
can include padding or cushioning.
[0095] FIG. 2A and FIG. 2B represent an isometric and side view,
respectively, of an exemplary exercise apparatus 100 in accordance
with an embodiment. In some embodiments, the thigh members (202a
and 202b) contain one or more contact areas surrounding a hollow
area. The distance between the contact areas surrounding a hollow
area can vary. The one or more contact areas can include bars or
tubes of various sizes, as well. The contact areas may be more
rounded to mimic the shape of a thigh. Thigh members 202a and 202b
can be used with any of the embodiments here, including replacing
thigh members 102a, 102b, 302a, 302b, 402a, and 402b.
[0096] In some embodiments, a width of a thigh member 102a or 102b
can be between 2 and 12 inches, including between 4-8 inches,
including 6 inches. In some embodiments, the width of a thigh
member is not uniform, but can vary at different points of the
thigh member. In some embodiments, a height of a thigh member 102a
or 102b is between 4 and 12 inches, including 7, 8, or 9 inches. In
some embodiments of a curved or concave thigh member, the top
portion of thigh members 202a and 202b that are adapted to contact
the top of a user's thighs can have a length of between 2 and 10
inches, including 5, 6, 7, 8 or 9 inches.
[0097] As an exemplary advantage, the user can exercise his or her
thigh adductors in nearly any position, including while seated,
lying on his or her back, or while performing any of the other
exercises described herein, including while performing a crunch. In
some embodiments, the first thigh member 102a is parallel to the
second thigh member 102b. In some embodiments, the first thigh
member 102a is not parallel to the second thigh member 102b. For
example, in some embodiments, the first and second thigh members
are angled such that a distance between a side of the thigh members
closer to the user is smaller than a distance between a side of the
thigh members further from the user. In some embodiments, the
angles of the first thigh member 102a and second thigh member 102b
approximate the angle of a user's thighs when a user first engages
the first thigh member 102a and second thigh member 102b. In some
embodiments, the angles of the first thigh member 102a and second
thigh member 102b approximate the angle of a user's thighs when a
user varies the distance between the first thigh member 102a and
second thigh member 102b.
[0098] Returning to FIGS. 1A-1D, in some embodiments, apparatus 100
provides direct resistance to a user's chest comparable to doing a
decline bench crunch, which can target the rectus abdominus and
iliopsoas muscles. The chest contact member 101 can be configured
to move in a reciprocal motion relative to the chest crunch base
103, the thigh members (102a and/or 102b), or an abdominal crunch
base 104 when a user engages the chest contact member. The
reciprocal motion can include varying a distance between the chest
contact member and the chest crunch base 103, the thigh members
(102a and/or 102b), or the abdominal crunch base 104. The
reciprocal motion can also include being adapted to vary a distance
between the chest contact member and the chest crunch base 103, the
thigh members (102a and/or 102b), or the abdominal crunch base
104.
[0099] In some embodiments, a resistance member provides a
restoring force on the chest contact member 101 relative to the
chest crunch base 103, the thigh members (102a and/or 102b), or the
abdominal crunch base 104 when the distance decreases. Thus,
increasing the resistance can increase the force the abdominal
muscles must exert to overcome it. As an exemplary advantage,
increasing resistance can improve the effectiveness or efficiency
of the workout. As another exemplary advantage, providing
resistance to the chest can allow a user to perform the equivalent
of a decline crunch while in a seated position or while lying in a
flat and level position.
[0100] In some embodiments, the resistance member is included in
the connection between the chest contact member 101 and the chest
crunch base 103, the thigh members (102a and/or 102b), and/or the
abdominal crunch base 104.
[0101] The chest contact member 101 can be connected to the chest
crunch base 103 such that the reciprocal motion includes the chest
contact member 101 sliding over or inside of the chest crunch base
103 and guiding the chest crunch member 101 during the reciprocal
motion. The chest contact member 101 can include a contact surface
for engaging a user's chest 105. In some embodiments, the surface
105 is large enough to increase stability and user comfort during
use of apparatus 100. The surface can include a chest pad, such as
a foam cushion. The chest pad can be interchangeable with pads of
other sizes, shapes and materials to suit a particular user or
exercise. In some embodiments, the chest pad is smooth. In some
embodiments, the chest pad is textured. In some embodiments, the
texture is configured to increase friction between the surface 105
and the user's body to reduce slipping during use.
[0102] In some embodiments, the apparatus can be modular. In some
embodiments, a chest contact member and a chest crunch base can be
part of a chest module, an abdominal contact member and an
abdominal contact base can be part of an abdominal module, and a
first thigh member and a second thigh member can be part of a thigh
module. In some embodiments, one or more of the modules can be
detachable from the apparatus. In some embodiments, one of more of
the modules can be interchangeable on the apparatus. In some
embodiments, one or more of the modules can be permanently affixed
to the apparatus. In some embodiments, the chest contact member 101
is detachable from the remaining portions of the device. This may
include detaching a chest crunch base 103. Thus, the chest contact
member 101 and chest crunch base may comprise a modular component
that can be connected to the thigh members or the abdominal
contact/base member. In the same way, the thigh members may be
detachable and the abdominal contact member may be detachable.
[0103] In some embodiments, a length of a chest module can be
between 12 and 30 inches, including 20 inches. In some embodiments,
the length of the chest contact member can be between 6 and 30
inches, including 8, 12, 16, and 20 inches. In some embodiments,
the length of a chest crunch base can be between 6 and 30 inches,
including 8, 12, 16, 20, and 24 inches.
[0104] In some embodiments, a length of an abdominal module can be
between 12 and 30 inches, including 20 inches or 22 inches. In some
embodiments, the length of the abdominal contact member can be
between 6 and 30 inches, including 8, 10, 12, 16, 20, 22, and 24
inches. In some embodiments, the length of an abdominal crunch base
can be between 6 and 30 inches, including 8, 10, 12, 16, 20, 24
inches.
[0105] In some embodiments, a length of a proximal end of a chest
contact member to a distal end of a chest crunch base is 16, 18,
20, 22, or 24 inches when the chest contact member and the chest
crunch base are coupled and in an extended position. In some
embodiments, a length of a proximal end of a chest contact member
to a distal end of a chest crunch base is 8, 10, 12, 14, or 16
inches when the chest contact member and the chest crunch base are
coupled and in a compressed position. In some embodiments, the
ratio of a (1) length of a proximal end of a chest contact member
to a distal end of a chest crunch base when the chest contact
member and the chest crunch base are coupled and in an extended
position to (2) a length of a proximal end of the chest contact
member to a distal end of the chest crunch base when the chest
contact member and the chest crunch base are coupled and in a
compressed position is 2:1, 5:3, or 3:2.
[0106] In some embodiments, a length of a proximal end of an
abdominal contact member to a distal end of an abdominal crunch
base is 16, 18, 20, 22, or 24 inches when the abdominal contact
member and the abdominal crunch base are coupled and in an extended
position. In some embodiments, a length of a proximal end of an
abdominal contact member to a distal end of an abdominal crunch
base is 8, 10, 12, 14, or 16 inches when the abdominal contact
member and the abdominal crunch base are coupled and in a
compressed position. In some embodiments, the ratio of (1) a length
of a proximal end of an abdominal contact member to a distal end of
an abdominal crunch base when the abdominal contact member and the
abdominal crunch base are coupled and in an extended position to
(2) a length of a proximal end of the abdominal contact member to a
distal end of an abdominal crunch base when the abdominal contact
member and the abdominal crunch base are coupled and in a
compressed position is 2:1, 5:3, or 3:2.
[0107] In some embodiments, the ratio of (1) a length of a proximal
end of an abdominal contact member to a distal end of an abdominal
crunch base when the abdominal contact member and the abdominal
crunch base are coupled and in an extended position to (2) a length
of a proximal end of a chest contact member to a distal end of a
chest crunch base when the abdominal contact member and the
abdominal crunch base are coupled and in an extended position is
1:1. If the ratio deviates from a 1:1 ratio in the extended,
contracted, or partially contracted positions, use can become
awkward or uncomfortable. In particular, if the ratio is too low in
any of these positions, the user can experience undue upward
slippage of the chest contact member relative to their chest.
[0108] In some embodiments, the chest crunch base 103 is connected
to the abdominal crunch base 104 by a hinge 106. In some
embodiments, a main body of the apparatus comprises the chest
crunch base 103, the abdominal crunch base 104, the hinge 106, and
the thigh base 112. In some embodiments, the chest contact
member/chest contact base can be detachably connected. In some
embodiments, the height or angle of the chest contact member 101
relative to the thigh members can be adjusted, for example, by the
hinge 106 connected to chest crunch base 103.
[0109] The user can adjust the height or angle of the chest contact
member to accommodate different exercises or different users. In
some embodiments, the height or angle of the chest contact member
can be reversibly locked in a desired position using a lock, such
as a quick release lever 117. Some embodiments include a quick
release mechanism that is conveniently manipulated without great
strain and with one hand, or just the force from one or a few
fingers, so the other hand is free to hold the apparatus while the
user completes the adjustment. In some embodiments, the user can
adjust the angle of the chest contact member relative to the
abdominal contact member at any angle between 0.degree. (for
example, parallel to the abdominal contact member) and 90.degree.
(for example, greater perpendicular to the abdominal contact
member). In some embodiments, the user can set the angle of the
chest contact member relative to the abdominal contact member at
0.degree., 10.degree., 20.degree., 30.degree., 40.degree.,
45.degree., 50.degree., 60.degree., 70.degree., 80.degree., or
90.degree.. In some embodiments, the user can set the angle of the
chest contact member relative to the abdominal contact member at
30.degree., 40.degree., 45.degree., or 50.degree..
[0110] Apparatus 100 can also assist a user in performing a lateral
resistance pull. This exercise can target the back muscles,
including latissimus dorsi (lats), teres major, and trapezius
muscles. The abdominal crunch base 104 can be generally
rectangular. The abdominal crunch base 104 can include one or more
handles 107. The one or more handles 107 can be positioned on one
or more sides of the abdominal crunch base 104. Each handle 107 can
include one or more handgrips 108 or arm supports 109. Apparatus
100 can also include an abdominal contact member 110. The abdominal
contact member 110 can be configured to move in a reciprocal motion
relative to the abdominal crunch base 104 when a user engages the
abdominal contact member 110. Thus, the user can perform a lateral
resistance pull by engaging the handgrips 108 with the user's hands
and pulling the abdominal crunch base 104 towards the user's
abdomen in a reciprocal motion. The reciprocal motion can include
varying a distance, or being adapted to vary a distance, between
the abdominal crunch base 104 and the abdominal contact member 110,
the chest crunch base 103, and/or the thigh members (102a and
102b). In some embodiments, apparatus 100 can include a resistance
member that is configured to provide a restoring force on the
abdominal contact member 110 when the user moves the abdominal
crunch base 104 in a reciprocal motion. In some embodiments, the
resistance member is included in the connection between the
abdominal contact member 110 and the abdominal crunch base 104, the
thigh members (102a and/or 102b), and/or the chest crunch base 103.
Exemplary abdominal contact members and backings for abdominal
contact members are provided in FIGS. 15A-15F.
[0111] In some embodiments, apparatus 100 provides direct
resistance to the front abdominals comparable to doing crunches
slowly with a weighted medicine ball resting on the abdomen. This
exercise can target the middle and upper abdominal muscles, the
lower back, and the core. The abdominal contact member can include
a contact surface 111 for engaging a user's abdomen. The contact
surface 111 can be of any size. In some embodiments, the surface
111 is large enough to increase stability and user comfort during
use of the apparatus. The surface 111 can include a pad, such as a
foam cushion. The pad can be interchangeable with pads of other
sizes, shapes and materials to suit a particular user or exercise.
As the distance between the abdominal contact member 110 and the
abdominal crunch base 104 decreases, the amount of pressure the
contact surface 111 places on the abdomen can increase.
[0112] Various configurations of the apparatus are possible. For
example, different configurations can comprise different
combinations of components. The combinations can include some or
all of the components described above. Adding or withdrawing
components can provide for different exercises, isolation of
different muscle groups, or different methods of use. Thus, in some
embodiments, the modular components of the device can be used
independently, or combined in various configurations to provide for
customized workouts.
[0113] FIG. 3A represents an isometric view of an exemplary

[0121] FIG. 6, FIG. 7, and FIG. 8 illustrate exemplary methods of
using the apparatus in accordance with various embodiments of the
present disclosure. The exercise methods of FIGS. 6-8 can be used
to perform exercises using the various apparatuses disclosed
herein, but the methods are not limited to using the various
apparatuses disclosed herein. In some embodiments, where a modular
component is not included in an apparatus, the corresponding motion
in FIGS. 6-8 is not performed.
[0122] In some embodiments, a method of exercising using an
exercise apparatus includes engaging a first thigh member and a
second thigh member, engaging a chest contact member, overcoming a
restoring force provided by a first resistance member to vary a
first distance between the first and second thigh members to move
the first and second thigh members in a first reciprocal motion,
and overcoming a restoring force provided by a second resistance
member to vary a second distance between the chest contact member
and at least one of the first and second thigh members to move the
chest contact member in a second reciprocal motion, wherein
overcoming the restoring force provided by the first resistance
member is performed simultaneously with overcoming the restoring
force provided by the second resistance member.
[0123] FIGS. 6A and 6B depict an exemplary method of varying a
distance between the first and second thigh members in a reciprocal
motion. FIGS. 7A and 7B depict an exemplary method of varying a
distance between the chest contact member and at least one of the
first and second thigh members to move the chest contact member in
a reciprocal motion. FIGS. 7A and 7B also depict the user varying a
distance between the abdominal contact member and at least one of
the first and second thigh members to move the abdominal contact
member in a reciprocal motion. This motion can simulate the use of
an abdominal medicine ball when the device is pulled toward the
user in the lateral pull motion, described above. Also as
previously described, the first and second thigh members can be
attached to the apparatus at a fixed position in some embodiments.
FIGS. 7A and 7B show the thigh members sliding along the user's
thighs as the user pulls the apparatus towards his abdomen in a
lateral pull.
[0124] In some embodiments, the method of exercising includes
engaging an abdominal crunch member comprising an abdominal contact
member and overcoming a restoring force provided by a resistance
member to vary a distance between the abdominal contact member and
at least one of the first and second thigh members to move the
abdominal contact member in a reciprocal motion. FIGS. 7A and 7B
also depict an exemplary method of varying a distance between the
abdominal contact member and at least one of the first and second
thigh members to move the chest contact member in a reciprocal
motion. In some embodiments, the method of exercising includes
engaging an abdominal contact member and overcoming restoring force
provided by a resistance member to vary a distance between the
abdominal contact member and an abdominal crunch base to move the
abdominal contact member in a reciprocal motion.
[0125] FIGS. 8A and 8B depict an exemplary method of varying a
distance between the chest contact member and at least one of the
first and second thigh members to move the chest contact member in
a reciprocal motion. FIGS. 8A and 8B also depict the user varying a
distance between the abdominal contact member and the abdominal
crunch base to move the abdominal contact member in a reciprocal
motion. This motion can simulate the use of an abdominal medicine
ball when the device is pulled toward the user in the lateral pull
motion, described above. Also as previously described, the first
and second thigh members can be attached to the apparatus such that
the first and second thigh members slide along the abdominal crunch
base or abdominal contact member in some embodiments. FIGS. 8A and
8B show the thigh members sliding along the abdominal crunch base
and remaining in a fixed position relative to the user's thighs as
the user pulls the apparatus towards his abdomen in a lateral
pull.
[0126] In some embodiments, the method of exercising includes
engaging one or more handles to vary one or more of the distances.
For example, in some embodiments, engaging the abdominal crunch
exercise member includes grasping the handles 107 and pulling the
device 100 toward the user, as in FIGS. 6A and 7B. This motion can
correspond to an exercise traditionally performed as a cable row or
on a rowing machine. The user's hands can be positioned such that
his or her palms are facing up, down, or towards each other. When
the user's palms face up, the user can exercise his or her lower
abs, middle abs, side abs, lats, back and arms. When the user's
palms face down or each other, the user can exercise the same or
different muscles, and such exercises can have the same or
different effects. For example, a user may primarily exercise
triceps and shoulder muscles with palms facing down.
[0127] In some embodiments, the method of exercising includes
overcoming a restoring force provided by a resistance member to
vary a distance between one or more of the first and second thigh
members 102a and 102b and chest contact member 101 to move one or
more of the first and second thigh members 102a and 102b in a
reciprocal motion. In some embodiments, the method includes the
user engaging the first and second thigh members by lifting his or
her legs to move one or more of the first and second thigh members
in the reciprocal motion. In some embodiments, overcoming the
restoring force provided by the resistance member is performed
simultaneously with overcoming the restoring force provided by any
one or more of the other resistance members described herein.
[0128] In some embodiments, the motions include pulling the
apparatus towards the user, crunching the abdomen, adducting the
thighs, and/or holding any or all of these motions. The user can
perform these motions in any order, in any combination, or
simultaneously. These motions can exercise most or all core muscles
and the thighs. This allows a user to exercise these multiple
muscle groups simultaneously using a single device. Simultaneously
exercising these muscle groups allows the user to compound the
effects of individual exercises compared to using no machine or
traditional machines configured to exercise only a single muscle
group at once.
[0129] In some embodiments, a user can use the apparatus in a
seated position, lying on his or her back on the floor, in a hybrid
seated/lying down position, or at an incline or decline. In
accordance with various embodiments, use of the apparatus in a
sitting position can provide a beginner exercise, use of the device
in a lying down position can provide an intermediate exercise, and
use of the device in a hybrid sitting/laying down position can
provide an advanced exercise. Use of the apparatus in any of these
positions can also alter the resistance and muscle groups used,
thereby providing different workouts.
[0130] In addition, the putting pressure on the frontal abdominals
using the apparatus can prevent lordosis or curvature of the lower
back. This can reduce pressure on the lower back, critical to
individuals with low back pain. As discussed above, a user can
perform a "crunch" by crunching against the chest contact member
101. This can exercise the upper abs. It should also be noted that
the figures illustrated the crunch motion in a rotational fashion;
however, the crunch can also be performed at a straight angle. In
other words, a user can push his or her chest so that the chest
contact member 101 moves straight into the body of the device 100,
as discussed above.
[0131] FIG. 9A and FIG. 9B represent isometric cutaway views of an
exemplary resistance member 900 in accordance with an embodiment.
In some embodiments, the resistance member comprises a first anchor
903, and a second anchor 905 configured to move in a reciprocal
motion relative to the first anchor 903. In some embodiments, the
resistance member comprises a spring 901. In some embodiments, the
spring resists relative movement of the first and second anchor in
a first direction of the reciprocal motion. In some embodiments,
the spring aids relative movement of the first and second anchor in
a direction of the reciprocal motion opposite to the first
direction. In some embodiments, the reciprocal motion is between 2
and 18 inches, between 4 and 16 inches, between 5 and 12 inches, or
between 6 and 8 inches. In some embodiments, the reciprocal motion
is 2, 3, 4, 5, 6, 7, 8, or 9 inches.
[0132] In some embodiments, the spring 901 can be connected to the
first and second band connectors 902a and 902b such that the first
and second band connectors are configured to move in a reciprocal
motion. The reciprocal motion can include varying a distance
between the first band connector 902a and second band connector
902b, or can include being adapted to vary a distance between the
first band connector 902a and second band connector 902b. In some
embodiments, varying a distance between the first band connector
902a and the second band connector 902b elongates the spring 901.
In some embodiments, elongating the spring increases the tension on
the spring, thereby increasing the resistance provided by the
resistance member.
[0133] In some embodiments, the spring comprises a continuous band
encircling a first band connector 902a and a second band connector
902b. In some embodiments, the continuous band is ring-shaped,

inches, between 1/2 of an inch and 16 inches, between 1 inch and 14
inches, between 2 inches and 12 inches, between 3 and 8 inches,
between 3.5 and 6 inches, or between 4 and 5 inches. In some
embodiments, the spacer is configured to maintain a distance
between the first anchor and the second anchor of 1/8, 1/4, or 1/2
of an inch, or 1, 2, 3, or 4 inches.
[0136] In some embodiments, the first band connector 902a is
connected to the first anchor 903. In some embodiments, the first
anchor 903 comprises a lip, a rib, or an edge. In some embodiments,
the first anchor 903 is part of a shell 904 or cover encasing at
least a portion of the tension band. In some embodiments, the base
connector can be configured to connect the resistance member to a
chest contact member, chest crunch base, abdominal contact member,
or abdominal crunch base such that the resistance member provides a
restoring force when a user engages the device.
[0137] In some embodiments, the anchors 903 and 905 can be
configured to connect the resistance member to a chest contact
member, chest crunch base, abdominal contact member, or abdominal
crunch base such that the resistance member provides a restoring
force when a user engages the device. For example, in some
embodiments the first anchor 903 is configured to connect the
resistance member to a chest contact member and the second anchor
905 is configured to connect the resistance member to a chest
crunch base. In some embodiments, the first anchor 903 is

member to a chest contact member. In some embodiments, the first
anchor 903 is configured to connect the resistance member to an
abdominal contact member and the second anchor 905 is configured to
connect the resistance member to an abdominal crunch base. In some
embodiments, the first anchor 903 is configured to connect the
resistance member to an abdominal crunch base and the second anchor
905 is configured to connect the resistance member to an abdominal
contact member.
[0138] In some embodiments, the resistance member includes a
housing for containing the first anchor, second anchor, and the
spring. In some embodiments, the housing has a length between 2-20
inches, between 2.5 and 12 inches, between 3 and 8 inches, between
3.5 and 6 inches, or between 4 and 5 inches, a width of between 1

In some embodiments, the resistance member comprises a spring 1101.
In some embodiments, the resistance member comprises a first spring
1102a connector and a second spring connector 1102b. In some
embodiments, the distance between the first spring connector 1102a
and second spring connector 1102b is fixed. Is some embodiments, a
spring 1101 is connected to the first spring connector 1102a and
second spring connector 1102b. In some embodiments, the resistance
member comprises a paddle 1103 configured to engage the spring. In
some embodiments, the paddle 1103 is configured to move in a
reciprocal motion relative to the first and second spring
connectors 1102a and 1102b. In some embodiments, the spring 1101
resists relative movement between the paddle and the first and
second anchors in a first direction of the reciprocal motion. In
some embodiments, the spring 1101 aids relative movement between
the paddle 1103 and the first and second spring connectors 1102a
and 1102b in a direction of the reciprocal motion opposite the
first direction. In some embodiments, the reciprocal motion is
between 2 and 18 inches, between 4 and 16 inches, between 5 and 12
inches, or between 6 and 8 inches. In some embodiments, the

[0151] In some embodiments, the springs 1001, 1101, and 1201 are
interchangeable. In some embodiments, varying the length,
elasticity, or thickness of a spring can vary the resistance the
tension band can provide. In some embodiments, the springs provide
between 5 and 160 pounds of resistance. In some embodiments, the
spring provides 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65,
70, 80, 90, 100, 110, 120, 130, 140, 150, or 160 pounds of
resistance.
[0152] FIGS. 13A and 13B illustrate abdominal contact members
configured to be used with the springs of FIGS. 11 and 12. The
abdominal contact member in FIG. 13A includes a wider base 1302
than the base 1304 in FIG. 13B. Each of the abdominal contact
members comprises a paddle 1303. FIG. 13B also illustrates a cover
1306 configured to removably engage with an abdominal contact base.
The cover comprises a lever with a nub 1307, which can secure the
cover 1306 to the abdominal contact base.
[0153] FIG. 14 illustrates an exercise apparatus comprising a chest
contact member 1402 adapted to receive a chest crunch base,
including the exemplary chest crunch base 103 depicted in FIG. 1A.
The chest crunch base comprises an insert and the chest contact
member comprises a tube, wherein the insert is configured to move
in a reciprocal motion within the tube. The tube comprises a hollow
internal space comprising an inner wall 1406. The insert comprises
an outer wall. In some embodiments, the outer wall of the chest
crunch base comprises a rail. The tube includes complimentary
guides 1410a and 1410b to prevent contact between the inner wall of
the tube and outer wall of the chest crunch base during the
reciprocal motion. In some embodiments, the complementary guides
1410a and 1410b engage and guide the rail of the chest crunch base.
In some embodiments, the complementary guides 1410a and 1410b
reduce friction or vibration caused by the reciprocal motion
between the chest contact member and the chest contact base.
[0154] FIGS. 15A to 15F illustrate exemplary contact members and
backings for abdominal contact members and chest contact members in
accordance with some embodiments. FIG. 15A illustrates an abdominal
contact member with six contact protrusions in accordance with an
embodiment. FIG. 15B illustrates a backing for the abdominal
contact member of FIG. 15A. FIG. 15C illustrates an abdominal
contact member with four contact protrusions in accordance with an
embodiment. FIG. 15D illustrates a backing for the abdominal
contact member of FIG. 15C. FIG. 15E illustrates a chest contact
member in accordance with an embodiment. In some embodiments, the
chest contact member is textured. In some embodiments, the chest
contact member comprises grooves. In some embodiments, the chest
contact member is curved or concave. The curve or concave shape can
be adapted to contact a user's chest. FIG. 15F illustrates a chest
contact member in accordance with an embodiment. In some
embodiments, the chest contact member is not concave, and is flat
or substantially flat relative to the length, the width, or both
the length and width of the chest contact member.
[0155] Through contact prevention, the complimentary guides may
allow for freer relative motion of the base and body contact member
during the reciprocal motion. Further, by preventing contact, the
complimentary guides may allow for a longer life of the base and
body contact member. In some embodiments, the complimentary guides
may reduce an angular range of motion of the tube relative to the
insert. In some embodiments, the complementary guides comprise a
bearing and a female guide rail.
