TECHNICAL FIELD
[0002] The present invention relates to exercise devices, e.g.,
resistance exercise devices, and particularly to devices for
strengthening core muscles.
BACKGROUND
[0003] Performing an effective trunk twist requires targeting the
core muscles. When performing trunk exercises an exerciser must use
a machine or device to stabilize the upper body to avoid using the
muscles of the scapula and glenohumeral joint. By avoiding the use
of these shoulder muscles an exerciser maximizes the use of the
core muscles of the trunk, thus strengthening those core muscles in
the most effective manner. Until now, the only exercise machines
that could maximize the use of core muscles were extremely bulky
and expensive. For those reasons, the previous art was typically
suitable for only large commercial gyms.
[0004] Traditionally, trunk twist exercises have been performed
either (1) on a seated torso rotation machine, which stabilizes
both the upper and lower body, such as the technology disclosed by
U.S. Pat. No. 4,456,245 ("the '245 patent"), or (2) standing, with
arms extended holding a cable or a resistance band, such as the
technology disclosed by U.S. Pat. No. 7,625,321 ("the '321
patent").
[0005] The seated torso rotation machine is effective by providing
a guided path of motion, parallel to the resistance, and the trunk
muscles are driving the majority of the force necessary to complete
the exercise. In this exercise, sitting down stabilizes the lower
body, the shoulder pads stabilize the shoulder complex, and thus
the upper body alone drives the force of motion. Accordingly, the
trunk muscles are sufficiently isolated, requiring the trunk
muscles to perform a majority of the work. However, the machine is
too expensive and too bulky for many commercial gyms, and virtually
all home gyms.
[0006] Because a seated torso rotation machine is often
unavailable, many exercisers perform a trunk twist exercise
standing, with arms extended, holding a cable or a resistance band,
and twisting in each direction. With the standing exercise, because
the exerciser is holding the cable at arm's length in front of the
chest, the shoulder complex influences the effectiveness of the
exercise. In this exercise, where the load is distal to the body,
this lack of stability and restraint in the upper body greatly
reduces the amount of force through the trunk. But, because the
arms and shoulders are still working to perform the twist, and
exerciser often does not realize that the arms and shoulders are
helping to perform the exercise, reducing the amount of force
through the trunk. In an effort to alleviate this problem, users
can perform this exercise holding a large exercise ball in between
the arms. The addition of the exercise ball greatly increases the
stability through the shoulder complex, making the exercise more
efficient, but holding the ball between the arms is virtually
impossible because the ball is bulky and uncomfortable to hold.
[0007] The Ground Force 360, which is explained at
http://rotationalexercise.com/ground-force-360/, is similar to the
seated torso rotation machine, as disclosed in the '245 patent,
because it effectively loads the trunk muscles and provides a
guided path of resistance that is parallel to the path of motion.
In this exercise, the user stands at the machine and has
shoulder-stabilizing pads on the front and back of each shoulder.
Similar to the shoulder pads in the '245 patent, the shoulder pads
on the Ground Force 360 stabilize the shoulder complex, allowing
the user to drive the maximum amount of force through the trunk
muscles. However, the Ground Force 360, similar to the seated torso
rotation machine, is too expensive and too bulky for most
commercial gyms, and virtually all home gyms.
[0008] Trunk twists may also be performed by adding weight to an
exerciser's shoulders at the back of the neck using a weighted bar,
such as the technology disclosed by U.S. Pat. No. 5,312,314 ("the
'314 patent), or similarly with a semicircular bar as disclosed in
U.S. Pat. No. 5,248,287 ("the '287 patent"). These exercises,
however, load the trunk muscles inefficiently. Exercise is most
effective when loads and the direction of resistance are
parallel.
[0009] The load and resistance in this exercise is perpendicular to
the path of motion.
[0010] Accordingly, this exercise is not an effective way to load
the trunk muscles for a twisting exercise.
[0011] Another method of adding resistance is by using air
resistance with a paddle on the shoulders that would provide air
resistance during a twisting motion, such as the technology
disclosed in U.S. Pat. No. 4,603,854 ("the '854 patent"). Because
of the air paddles, the load and the direction of resistance are
parallel. However, the speed of motion, which dictates the amount
of force, requires an exerciser to move faster in order to increase
resistance. The faster motion leads to a greater risk of injury.
Accordingly, using air resistance with a paddle on the shoulders,
because it does not allow the user to increase the resistance while
maintaining a constant speed, is not the most effective way to
perform this exercise.
[0012] Despite existing resistance based exercise machines, there
still exists problems with the existing machines that stabilize the
upper body, removing the scapular/glenohumeral involvement in a
trunk twist, because these machines are bulky, not portable, and
expensive. There also still exists problems with other machines and
methods that are more portable and/or less expensive, because those
machines and methods fail to stabilize the upper body, thus
allowing scapular/glenohumeral involvement in a trunk twist
exercise, and thus greatly reducing the amount of force production
through the trunk and core muscles. In most of these methods and
exercises, the load is also not the most efficient for the
exercise: it is either distal to the body, or it is not parallel to
the direction of resistance.
[0013] Despite existing resistance based exercise machines, there
still exists a need for a resistance based trunk rotation device
which is portable, lightweight, less bulky, less expensive,
stabilizes the upper body, removing scapular/glenohumeral
involvement in the exercise, and thus increasing the efficiency of
the exercise and the ability of the exercise to exert production
through the trunk and core muscles, and can be loaded progressively
over time as the exerciser gets stronger.

EXAMPLES
Example 1
[0160] In one illustrative example of performing a trunk twist with
one embodiment of the exercise device, an exerciser attaches
resistance to the means for attaching resistance, 18. The exerciser
hugs the support means, 10, to his or her chest, with one arm above
and parallel to the quarter-wheel, 12, while the other arm is below
and parallel to the quarter-wheel, 12. The means for attaching
resistance, 18, is in the center of the quarter-wheel along the
outer edge. The exerciser then performs a trunk twist turning away
from the resistance. To perform a trunk twist in the opposite
direction, the exerciser reorients the resistance and the exercise
device to the opposite side.
Example 2
[0161] In one example, the apex of the quarter-wheel, 12, is
approximately 25 to 40 cm from an exerciser's chest providing
adequate distance from the body for resistance to the trunk
muscles, just as a human arm does in a trunk twist without an
exercise device. However, unlike the human arm, the exercise device
is always stable. As a result, the exercise device allows an
exerciser to perform a trunk twist while stabilizing the upper
body, removing the scapular and glenohumeral involvement in a trunk
twist and allowing for more efficient and greater force production
through the trunk. In addition, when fully twisted, the amount of
resistance is less than at neutral, which correlates to the human
body's natural force production capabilities because when the
muscles are in a shortened position, as they are when the trunk is
fully twisted, muscles produce less force.
[0162] When the trunk twist is performed with the exercise device,
the path of motion remains constant throughout the entire twist
because the resistance travels along the groove 14 to guide the
cable.
Description of Exemplary Benefits
[0163] From the description above, a number of advantages of some
embodiments of the exercise device become evident:
[0164] 1. The exercise device stabilizes the upper body, removing
the scapular/glenohumeral involvement in a trunk twist, which
allows for more efficient and greater force production through the
trunk.
[0165] 2. The exercise device is less expensive, more attractive,
less bulky, and more portable than prior-art exercise devices. The
exercise device is the only way to attach external load proximately
to a user's trunk using a portable device.
[0166] 3. The exercise device can use any source of external
resistance, including a weight stack or an exercise band.
[0167] 4. The support means is contoured so that it will be
comfortable for the user.
[0168] 5. The means for maintaining contact between the resistance
cable and the quarter-wheel guides the user to use the appropriate
path of motion.
[0169] 6. The user can use the exercise device to perform a trunk
twist with or without additional hip rotation.
[0170] 7. The exercise device can be used to add resistance to
other exercises, including crunches.
[0171] The exercise device and various embodiments can be used to
perform a trunk twist, or other resistance exercises, more
effectively and with a lower cost, smaller device. In addition,
when it is used, the exercise device can guide the user in the
appropriate path of motion without having to use a more cumbersome
machine that locks the user into a certain path of motion.
[0172] Although the descriptions above contain many specificities,
these should not be construed as limiting the scope of other
potential embodiments but as merely providing illustrations of some
of the several embodiments. For example, the support means
comprises one or more pieces, e.g., a triangular piece, a "V"
shaped piece, or a "Y" shaped piece similarly the means for
attaching resistance can include various methods attached at any
point along the quarter-wheel. Likewise, a half-wheel or
quarter-wheel may be used. Thus, the scope of the embodiments
should be determined by the appended claims and their legal
equivalents, rather than by the examples given.
[0173] Moreover, it should be understood that various features
and/or characteristics of different embodiments herein may be
combined with one another. It is therefore to be understood that
numerous modifications may be made to the illustrative embodiments
and that other arrangements may be devised without departing from
the scope of the invention.
[0174] Furthermore, other embodiments of the invention will be
apparent to those skilled in the art from consideration of the
specification and practice of the invention disclosed herein. It is
intended that the specification and examples be considered as
exemplary only, with a scope and spirit being indicated by the
claims.
[0175] Finally, it is noted that, as used in this specification and
the appended claims, the singular forms "a," "an," and "the,"
include plural referents unless expressly and unequivocally limited
to one referent, and vice versa.
