Exercise apparatus for performing squats
Abstract
An exercise apparatus for performing squats is disclosed and
includes in the preferred embodiment a frame, a base platform, a
yoke assembly, a pair of weight carriages and a pair of universal
joints. A pair of elongated handrails are attached to the frame. A
pair of adjustable yoke catch/supports are operatively associated
with the frame. A pair of vertical rods are disposed at each side
of the frame for guiding the travel of the weight carriages when in
use. The yoke assembly includes a padded neck and shoulder portion,
with the shoulder pads being contoured. The weight carriages
provide support for the weight plates. The location of the weight
supports allow the weight plates to be disposed approximate to the
height of the user's waist and closer to the user's center of
gravity. A first universal joint connects the first weight carriage
to the yoke assembly and a second universal joint connects the
second carriage member to the yoke assembly. The universal joints
allow for multidimensional movement of the yoke assembly and
provide the exerciser with a greater freedom of movement, similar
to the traditional "squat" exercise with free weights. The
universal joints allow for a free and individual arc of motion as
they serve as a fulcrum between the yoke assembly and the weight
carriages, thus, allowing the user's body's exercise motion to
occur in the sagittal plane as well as the frontal plane while the
weight moves vertically.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] None
BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The invention relates generally to the field of exercise
equipment, and particularly, to an exercise apparatus for
performing squats, lunges, adductors/abductors, heel raises,
etc.
[0005] 2. Description of Related Art
[0006] The "squat" exercise is one of the most popular exercises,
as it involves the use of many human muscles, including the
quadriceps group (front of the thigh), gluteus (buttocks),
hamstrings group (back of thigh), as well as the muscles of the
lower back, trunk and pelvis. The squat exercise also involves the
extension of the hip and knee joints, thus, stimulating the muscles
directly involved in the basic skills of jumping, running, kicking,
skipping, lifting and pushing. Additionally, the squat provides a
high systemic load on the performer's body, and greatly stimulates
the performer's neuromuscular system as well his or her skeletal
system. When performed with proper intensity, the squat exercise
places great demands on the body's bio-energy systems and can also
stimulate its neuro-endocrine systems.
[0007] The performance of the squat exercise involves the execution
of a variable depth deep knee bend from a standing position while
placing a variable resistance load upon the body. Traditionally,
squats are performed by use of equal amounts of free weights
disposed and retained at each end of a barbell, with the barbell
extending across the performer's shoulders and resting on his or
her upper trapezius muscles. The barbell is held in place by the
user gripping the barbell with his or her hands, preferably with a
slightly wider than shoulder width grip.
[0008] Some benefits from performing squat exercises include that
it is considered a "core" strength building exercise, it is a
weight bearing exercise that aids in the prevention of osteoporosis
and increases bone density, and it is a functional exercise that
stimulates actions performed daily by all able bodied
individuals.
[0009] However, the "squat" is a complicated exercise needing
caution and ability to perform safely and effectively. The proper
execution of a "squat" exercise involves the following: (1) proper
stance, (2) proper support of resistance load across the shoulders,
(3) maintenance of a straight or normally arched (extended) lower
back, (4) inclination of the trunk no more than forty-five
(45.degree.) degrees from the vertical, (5) keeping head neutral
and eyes forward, (6) keeping heels down, (7) lowering to a
position where thighs are horizontal, and (8) extending hips and
legs back to an upright position.
[0010] Though the squat exercise provides many benefits, there are
also safety concerns when performing this exercise. With the use of
free weights, the user exposes him or herself to risk of injury to
his or her lower back, knees, as well as his or her neck and
shoulder joints. Additionally, individuals with lower back and knee
problems often do not include squat exercises in the exercise
routines out of fear of further injury.
[0011] These safety concerns have caused many potential users to
avoid performing squats, or only to perform the exercise when a
spotter is available. Furthermore, the safety concerns often caused
the user to use a lower weight, than the user is capable of
properly lifting, thus reducing the optimal benefits the user could
achieve from the exercise.
[0012] Thus, what is needed in the art is an exercise apparatus
which permits a user to perform a squat without the risk of injury
associated with performing a squat with free weights, and also
without the need of a spotter. It is therefore, to the effective
resolution of the aforementioned problems and shortcomings that the
present invention is directed.
BRIEF SUMMARY OF THE INVENTION
[0013] The present invention provides an exercise apparatus for
performing squats, lunges, adductors/abductors, weighted heel
raises, etc. The exercise apparatus generally includes a frame
member, a base platform, a yoke assembly, a pair of weight carriage
members and a pair of universal joints. The frame member includes a
bottom section, a top section, back vertical sections attached to
the bottom section and the top section, and front vertical sections
also attached to the bottom section and the top section. The top
section can also include a cross beam or spanner attached along the
back of frame.
[0014] A first elongated handrail is attached to a first front
vertical section and a second elongated handrail is attached to a
second front vertical section. A first plurality of apertures are
provided along a portion of the first front vertical section and a
second plurality of apertures are provided along a portion of the
second front vertical section.
[0015] A first catch member is associated with the first front
vertical section and remains attached to the front section through
a pin portion inserted within one of the apertures. The catch
member can be moved/slid along vertical section by pulling its
handle which causes the catch member's pull pin to be removed or
withdrawn from its position within one of the apertures. Once the
catch member is properly positioned, the user releases the handle
causing the pin portion to be inserted into the aligned aperture. A
wall portion of the catch member, along with a portion of first
front vertical section define a first yoke receiving/support area.
Similarly, a second catch member, having a handle and pull pin, is
associated with the second front vertical section and its plurality
of apertures.
[0016] A first pair of vertical guide rods are preferably disposed
at a first end of the frame, and a second pair of vertical guide
rods are preferably disposed at a second end of the frame. The
guide rods extend from the bottom section to the top section and
are disposed intermediate of the back vertical sections and the
front vertical sections.
[0017] The base platform is preferably attached the bottom section.
At least a portion of the top surface of the base member can be
provided with a non-skid surface.
[0018] The yoke assembly preferably includes an integrally
constructed first horizontal portion, a neck and shoulder portion,
a first angled portion, a second horizontal portion, and a second
angled portion. A pair of contoured shoulder pads are preferably
provided at the bottom of the neck and shoulder portion.
Additionally, a neck pad can also be provided on an inner side of
the neck and shoulder portion.
[0019] A first weight carriage is provided at a first end of the
frame and a second weight carriage is provided at the second end of
the frame. The first carriage is provided with weight
supports/holders and moves vertically along its associated vertical
guide rods. Similarly, the second carriage is also provided with
weight supports/holders and moves vertically along its associated
vertical guide rods. The location of the weight supports allow the
weight plates to be disposed approximate to the height of the
user's waist and closer to the user's center of gravity.
[0020] A first universal joint connects the first weight carriage
to the yoke assembly and a second universal joint connects the
second carriage member to the yoke assembly. The universal joints
allow for multidimensional movement of the yoke assembly.
[0021] The pivotable nature of the universal joints provides the
user with a greater freedom of movement, similar to the traditional
"squat" exercise with free weights, and also ensures proper
technique, while also allowing the user to have an individualized
path of motion for the exercise and to maintain his or her natural
lordotic curve. The user is not forced to follow the path of motion
of the weight carriage members.
[0022] Thus, the universal joints act as an interface/pivot
point/fulcrum between the motive force and resistance force of the
exercise apparatus and provide the user an exercise path of motion
in the vertical, frontal and sagittal planes. The exercise
apparatus of the present invention, though considered a machine,
provides a user a with free weight squat motion. The user of the
present invention exercise apparatus is allowed to follow the
natural arc of the squat exercise, thus requiring use of all
stabilizing muscles used when performing a squat exercise with free
weights.
[0023] The universal joints allow for a free and individual arc of
motion as they serve as a fulcrum between the yoke assembly and the
weight carriage members. The universal joints allow for the user's
body's exercise motion to occur in the sagittal plane as well as
the frontal plane while the weight moves vertically. Additionally,
the resistance force of the weight acts predominantly at the body's
center of gravity and through its midline rather than at shoulder
height when using free weights, where it is known to push the
exerciser's upper body forward and down. The present invention
exercise apparatus preferably includes the following
characteristics: (1) self-spotting; (2) relatively heavily padded
neck and shoulder pads to decrease neck and shoulder joint strain;
(3) natural stance and bio-mechanics of a deep knee bend; (4)
ability to keep proper torso posture to protect lower back; (5)
range of motion limits well within fortyfive (45.degree.) degrees,
but still with enough mobility to promote neuromuscular recruitment
of the trunk and whole body proprioception and thus promote
stability for other athletic motion; (6) while providing for
comfort and safety, the exercise apparatus provides no mechanical
advantage and the user supports all of the weight, thus, providing
for a free weight feel; (7) multi-directional universal joint
(u-joint) allows the user to follow their own innate path of
motion, and does not force the exerciser with their unique
anatomical lever systems and biomechanics into a universal arc of
motion; (8) provides a four-point stance (feet and hands) to allow
the trunk to remain closer to vertical which in turn allows the
heels to remain on the ground upon lowering the body; and (9) four
point stance also helps to prevent the knees from crossing forward
over the vertical plane of the feet which helps to prevent knee
pain and injury.
[0024] Accordingly, it is an object of the present invention to
provide an exercise apparatus for performing squats.
[0025] It is another object of the present invention to provide an
exercise apparatus for performing squats without the risk of injury
associated with using free weights for the exercise.
[0026] It is still another object of the present invention to
provide an exercise apparatus for performing squats without the
necessity of having a spotter while performing the exercise.
[0027] In accordance with these and other objects which will become
apparent hereinafter, the instant invention will now be described
with particular reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0035] As seen in the drawings an exercise apparatus in accordance
with present invention is illustrated and generally designated as
reference numeral 20. Exercise apparatus generally includes a frame
member 30, base member or platform 80, a yoke assembly 90, a pair
of weight carriage members 110 and 130 and a pair of universal
joints 150 and 170.
[0036] Frame member 30 includes a bottom section 32 and a top
section 34. Back vertical sections 36 and 38 are provided and
attached at their first ends to bottom section 32 and at their
second ends to top section 34. Sections 36 and/or 38 can be
removably attached to sections 32 and/or 34 by conventional means
such as screws, bolts, nuts, washer combinations, etc.
Alternatively, sections 36 and/or 38 can be constructed integral
with sections 32 and/or 34. Front vertical sections 40 and 42 are
provided and attached at their first ends to bottom section 32 and
at their second ends to top section 34. Sections 40 and/or 42 can
be removably attached to sections 32 and/or 34 similar to the
attachments of back vertical sections 36 and/or 38 to section 32
and/or 34. Top section 34 can include a cross beam or spanner 68
attached along the back of frame. Spanner 68 can be removably
attached or constructed integral. Sections 32, 34, 36, 38, 40, 42
and 68 can be constructed from conventional materials such as
steel, aluminum, metal, etc.
[0037] A first elongated stationary grip member or handrail 44 is
attached to front vertical section 40 and a second elongated
stationary grip member or handrail 46 is attached to front vertical
section 42. The attachments of grip members 44 and 46 to vertical
sections 40 and 42, respectively, can be removable or constructed
integral. The preferred forward position of handrails 44 and 46,
allows apparatus 20 to be self-spotting, thus, permitting the user
to safely perform "squat" exercises alone and/or without the aid of
a spotter. Handrails 44 and 46 help to provide stability to the
user and also help to eliminate hyperextension of the user's
shoulders.
[0038] A first plurality of apertures (not shown) are provided
along a portion of front vertical section 40 and a second plurality
of apertures 50 are provided along a portion of front vertical
section 42. Though not shown, the first plurality of apertures are
similar to second plurality of apertures 50.
[0039] A first catch member 52 is associated with front vertical
section 40 and remains attached to section 40 through a pin portion
inserted within one of the apertures on section 40. Catch member 52
can be moved/slid along vertical section 40 by pulling its handle
54 which causes catch member 52's pull pin to be removed or
withdrawn from its position within one of the apertures of the
first plurality of apertures. Once catch member 52 is properly
positioned, the user releases handle 54 causing the pin portion to
be inserted into the aligned aperture. A wall portion 56 of catch
member 52, along with a portion of front vertical section 40 define
a first yoke receiving/support area 58. Similarly, a second catch
member 60, having a handle 62 and pull pin, is associated with
front vertical section 42 and its plurality of apertures 50. Second
catch member 60 also includes a wall portion designated reference
numeral 64. Wall portion 64, along with a portion of front vertical
section 42 define a second yoke receiving/support area 66.
[0040] The pull pins of catch members 52 and 60, in conjunction
with first and second plurality of apertures of front vertical
sections 40 and 42, respectively, allow for easy height adjustment
of catch members 52 and 60. Preferably, in use, catch members 52
and 60 are disposed at the same vertical height, though such is not
considered limiting, and the catch members can be disposed, if
desired, at different vertical heights. The length of first grip
member 44 and second grip member 46, as well as the height
adjustability of catch members 52 and 60, are preferably chosen to
accommodate the varying heights and arm lengths of different users
who may use apparatus 20.
[0041] A first pair of vertical guide members 70 and 72 is
preferably disposed at a first end of frame 30, and a second pair
of guide members 74 and 76 is preferably disposed at a second end
of frame 30. Guide rods 70, 72, 74 and 76 extend from bottom
section 32 to top section 34 and are disposed intermediate of back
vertical sections 36 and 38 and front vertical sections 40 and 42.
In the preferred embodiment guide members 70, 72, 74 and 76 are rod
or rod-like members, and thus substantially circular in
cross-sectional shape. Though not preferred, other shapes for guide
members can be provided, and are considered within the scope of the
invention. Vertical guide members 70, 72, 74 and 76 can be case
hardened, though such is not considered limiting.
[0042] Base member or platform 80 is preferably provided and
preferably attached at each of its to bottom section 32. Base
member 80 can be removably attached to bottom section 32 or
constructed or integral therewith both by conventional means. At
least a portion of the top surface of base member 80 can be
provided with a non-skid surface. When a user is performing an
exercise with apparatus 20, he or she preferably stands on base
member 80. Feet positioners or indicators, such as a lines or
markings, can be disposed on the top surface of platform 80 for
proper user feet positioning.
[0043] Yoke assembly 90 includes first horizontal portion 92
attached at its first end to a first side of a neck and shoulder
portion 94 and at its second end to a first angled portion 96. A
second horizontal portion 98 is attached at its first end to the
other side of neck and shoulder portion 94 and at its second end to
a second angled portion 100. Preferably, though not limiting, first
horizontal portion 92, neck and shoulder portion 94, first angled
portion 96, second horizontal portion 98 and second angled portion
100 are all constructed integral.
[0044] A pair of shoulder pads 102 and 104 are preferably provided
at the bottom of neck and shoulder portion 94 to provide cushioning
and comfort when a user is using apparatus 20 and the yoke assembly
is resting upon the user's shoulder area. Preferably, shoulder pads
102 and 104 can be contoured to correspond to the shape of the
user's shoulders and reduce compression to the user's cervical
vertebrae. In addition to providing comfort to the user, contoured
shoulder pads 102 and 104 also supply a greater contact area
between the user and the resistive force of yoke assembly 90, thus
spreading contact forces, as opposed to a conventional weight
lifting bar.
[0045] The use of yoke assembly 90, with shoulder pads 102 and 104,
eliminates the need for external rotation at the user's shoulder
joint(s) during the performance of the squat exercise motion with
apparatus 20. As such, stress to the joint(s) are relatively
greatly minimized, thus reducing injuries traditionally associated
with the "squat" exercise.
[0046] Additionally, a neck pad 106 can be provided on an inner
side of neck and shoulder portion 94 to provide protection and
cushioning to the back of the user's neck during use of apparatus
20.
[0047] A first carriage member 110 is provided at a first end of
frame 30 and a second carriage member 130 is provided at the second
end of frame 30. First carriage member 110 includes a substantially
vertically oriented body member 112 having a first tube-like member
114 disposed at one end and a second tube-like member 116 disposed
at its second end. One or more weight support members can be
associated with first carriage member 110. In the preferred
embodiment, a first weight support post 118 can protrude outward
from a first side of carriage member 110 and a second weight
support post 120 can protrude outward from a second side of
carriage member 110. Preferably, body member 112, tube-like members
114 and 116, and weight support posts 118 and 120 are constructed
integral, though such is not considered limiting. When properly
assembled, vertical guide member 70 extends out of both ends of
first tube-like member 114, while vertical guide member 72 extends
out of both ends of second tube-like member 116. Vertical members
70 and 72 act as vertical directional guides for first carriage
member 110 during use of apparatus 20.
[0048] Similarly, second carriage member 130 includes a
substantially vertically oriented body member 132 having a first
tube-like member 134 disposed at one end and a second tube-like
member 136 disposed at its second end. One or more weight support
members can be associated with second carriage member 130. In the
preferred embodiment, a first weight support post 138 can protrude
outward from a first side of carriage member 130 and a second
weight support post 140 can protrude outward from a second side of
carriage member 130. Preferably, body member 132, tube-like members
134 and 136, and weight support posts 138 and 140 are constructed
integral, though such is not considered limiting. When properly
assembled, vertical guide member 74 extends out of both ends of
first tube-like member 134, while vertical guide member 76 extends
out of both ends of second tube-like member 136. Vertical members
74 and 76 act as vertical directional guides for second carriage
member 130 during use of apparatus 20.
[0049] The location of the weight support posts allow the weight
plates to be disposed approximate to the height of the user's waist
and closer to the user's center of gravity. Thus, the user is not
pushed forward and down as in a free-weight squat.
[0050] The cross-sectional shape of weight support posts 118, 120,
138 and 140 are shown as being substantially circular. However,
such shape is not considered limiting. Preferably the
cross-sectional shape of the weight support posts is selected to
correspond to the shape of the aperture on the weights to be
supported. Preferably weight support posts, 118, 120, 138 and 140
are constructed from chrome, though other materials such as steel,
aluminum, metal, etc. can also be used and are also considered
within the scope of the invention.
[0051] Furthermore, other weights, not having center apertures, can
be used with the present invention. In these embodiments, the
weight supports associated with first carriage member 110 and
second carriage member 130 will also be modified or substituted
from posts 118, 120, 138 and 140, to safely retain the alternative
free weights. These alternative free weights and retaining
mechanisms are also considered within the scope of the
invention.
[0052] Preferably provided within tube-like members 114, 116, 134
and 136 are self-aligning linear bearings to provide a smooth and
durable operation of the tube-like members and vertical guide
members. Preferably, each tube-like member can be provided with
eight self aligning linear bearings, though such number is not
considered limiting.
[0053] A first universal joint 150 connects first carriage member
110 to yoke assembly 90 and a second universal joint 170 connects
second carriage member 130 to yoke assembly 90. Specifically, a
connection post 122 depends upwards from body member 112 of first
carriage member 110. The bottom of first universal joint 150 is
connected to first carriage post 122 by conventional means such as
bolts, nuts, etc. Similarly, a connection post 142 depends upwards
from body member 132 of second carriage member 130. The bottom of
second universal joint 170 is connected to second carriage post 142
also by conventional means. The top of first universal joint 150 is
connected to the outer end of first angled portion 96 of yoke
assembly 90, while the top of second universal joint 170 is
connected to the outer end of second angled portion 100 of yoke
assembly 90. Universal joints 150 and 170 allow for
multidimensional movement of yoke assembly 90 to promote
neuromuscular recruitment for the user of apparatus 20.
[0054] First universal joint 150 includes a first fixed U-shaped
member 152 and a second U-shaped member 154 pivotally connected to
first U-shaped member 152 (FIG. 3). First U-shaped member 152 is
attached to first carriage member 110 as discussed above, and
second U-shaped member 154 is attached to yoke assembly 90 as also
discussed above. Similarly, second universal joint 170 includes a
first fixed U-shaped member 172 and a second U-shaped member 174
pivotally connect to first U-shaped member 172. First U-shaped
member 172 is attached to second carriage member 130 as discussed
above, and second U-shaped member 174 is attached to yoke assembly
90 as also discussed above.
[0055] The pivotable attachment of second U-shaped member 154 to
first U-shaped member 152 of first universal joint 150 and the
pivotable attachment of second U-shaped member 174 to first
U=shaped member 172 of second universal joint 170 provide for the
multidimensional movement of yoke assembly 90 with respect to first
and second carriage members 110 and 130. This multidirectional
movement of yoke assembly 90 provides the user with a greater
freedom of movement, similar to the traditional "squat" exercise
with free weights, and also ensures proper technique, while also
allowing the user to have an individualized path of motion for the
exercise and to maintain his or her natural lordotic curve. The
user is not forced to follow the path of motion of weight carriage
members 110 and 130 of apparatus 20. With the use of apparatus 20,
the user is also able to recruit his or her stabilizing
muscles.
[0056] Universal joints 150 and 170 act as an interface/pivot
point/fulcrum between the motive force and resistance force in
exercise equipment, such as exercise apparatus 20. Universal joints
150 and 170 provide the user an exercise path of motion in the
vertical, frontal and sagittal planes. Thus, exercise apparatus 20
provides a user a free weight squat motion by a machine. The
multi-directional motion of yoke assembly 90 provides exercise
stimulus to the user's affected muscle groups well within safe
absolute limits of motion. Furthermore, the user is allowed to
follow the natural arc of the squat exercise, thus requiring use of
all stabilizing muscles used when performing a squat exercise with
free weights.
[0057] As seen in FIG. 6, in view of universal joints 150 and 170,
yoke assembly 90 is not required to be entirely at the same
vertical height. This varying height position for different parts
of yoke assembly 90, mimics the position of a barbell extending
across a exerciser's shoulders who is performing a free weight
squat. Furthermore, the location of front vertical section 40 and
42 cause the sections to act as forward stop members for yoke
assembly 90 (See FIG. 4). The backward stop for yoke assembly 90 is
provided by the construction of universal joints 150 and 170 (See
FIG. 5).
[0058] When using apparatus 20 the user carries the weight
distributed evenly across his or her body and does not need to
support a bar across his or her neck or trapezius muscles.
[0059] When in use, if the user is having difficulty completing a
repetition he or she can slide his or her hands up handrails 44 and
46 and easily assist him or herself. Alternatively, the user can
simply sit down until yoke assembly 90 reaches the bottom of its
permitted range of motion and slide out of the front of yoke
assembly 90.
[0060] The use of a universal joint(s), such as universal joints
150 and/or 170, in exercise equipment expands beyond its above
described use as part of exercise apparatus 20. Such additional use
of "universal joints" as fulcrums for other methods of resistance
force production include, but are not limited to, selectorized
plate stacks, tensions bands, hydraulics, compressed air,
electronics, and electro-magnetics.
[0061] Exercise apparatus 20 can be used in fitness clubs,
educational sport facilities and injury rehab centers, personal
home equipment, etc., and is not limited to any particular one use.
Apparatus 20 allows the "squat" exercise, as well as other
exercises, to be performed by all, regardless of age, gender or
fitness level. The ergonomic design of apparatus 20 helps to reduce
neck, back, shoulder and knee stress often associated with the
"squat" exercise. Apparatus 20 combines the safety advantages
associated with weight machines, with the benefits of free weight
movement and training. Some of the benefits of using exercise
apparatus 20 include: (1) the muscles used to train the user's
lower body are relatively safely recruited simultaneously; (2)
permits for the user's natural path of motion; (3) helps to
increase the user's lower body muscle strength; (4) helps to
increase the user's core body strength; (5) helps to increase the
user's balance; (6) helps to increase the user's muscular
hypertrophy; (7) helps to increase the user's neural patterns; (8)
helps to increase the user's ligaments and tendon strengths; (9)
helps to develop the large muscles of the user's lower back; and
(10) helps to increase the user's bone density.
[0062] Furthermore, exercise apparatus 20 is not limited to only
squat exercises. Apparatus 20 can also be used to perform common
exercises such as lunges, weighted toe raises, abductor/adductor
exercises, etc.
[0063] When performing a squat exercise the user steps on platform
80 and places his or her shoulder's into the contours or curves of
shoulder pads 102 and 104. The user preferably grabs onto handrails
44 and 46 (preferably at an approximate ninety (90.degree.) degree
elbow bend) and places his or her feet into an open scissor
position, with one of the user's legs in front of the other. The
user pushes forward with his or her rear leg until yoke assembly 90
contacts front vertical sections 40 and/or 42. Front vertical
sections 40 and/or 42 act as forward stops for yoke assembly 90. At
this point, yoke assembly 90 is slid up front vertical sections 40
and/or 42 until it passes the yoke guards. The user next stands
upright in an open scissor feet position and allows yoke assembly
90 to travel back towards its center. The user's back leg can be
used for support and controlling the movement of yoke assembly 90.
The user preferably places his heels forward so that his or her
knees do not past move out past his or her toes. Without leaning
forward and keeping his or her back straight, the user than squats
as if to sit on an imaginary stool placed behind the user. From
this bottom position, the user then rises back to an upright
position concentrating on applying force to the base platform
through the user's feet. This technique will help ensure that the
user employs proper individualized biomechanical exercise
technique. This up and down motion is preferably repeated until the
set is completed, at which time the user places his or her feet
back into an open scissor position. The user than leans forward to
allow yoke assembly 90 to again contact front vertical section 40
and/or 42. At this point, yoke assembly 90 is slid back down front
vertical sections 40 and/or 42 until it preferably rest within
catch members 52 and 60.
[0064] When performing lunges, the steps of the preceding paragraph
prior to the user squatting are preferably performed. Next the user
places one of his or her feet forward approximate to the front of
platform 80. The other foot is preferably placed off the back of
platform 80. While keeping his or her back erect, the user travels
downward and then pushes upward extending the forward leg back into
an upright position while concentrating on applying force to the
base platform through the foot. When the set is completed, yoke
assembly 90 is preferably returned to catch members 52 and 60 as
described above. As this exercise targets one leg at a time, the
user preferably switches leg positions and repeats the exercise for
the opposite leg.
[0065] When performing adductor/abductor exercises, the steps of
the initial steps for the squat exercise discussed above, prior to
the user squatting, are preferably performed. The user than takes a
relatively wide stance and turns his or her toes outward. Keeping
his or her back erect, the user travels downward, with his or her
adductors and abductors activated, and sits back into a squat
position. Preferably, the user's knees track with their associated
big and second toes. However, it is preferred that the user's knees
do not move pass his or her toes. At the squat position, keeping
his or her adductors and abductors activated, the user pushes up
through his or heels to the upright position. Once the set is
completed, yoke assembly 90 is preferably returned to catch members
52 and 60 as described above.
[0066] The instant invention has been shown and described herein in
what is considered to be the most practical and preferred
embodiment. It is recognized, however, that departures may be made
therefrom within the scope of the invention and that obvious
modifications will occur to a person skilled in the art.
