An exercise device comprising; a platform, a first limb attachment means, a first extendable cord attached to the first limb attachment means, the first extendable cord being at least partially located within the platform, and a tensioning means within the platform, wherein the tensioning means can be adjusted to alter the resistance of the first extendable cord to extension.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A running form training device for training a runner to properly position and move their arms includes a harness, a pair of bands, and a pair of cuffs. The harness can be donned by a user so that the harness is removably engaged to a torso of the user. The bands are resiliently stretchable. Each band is engaged to the harness so that the band extends from proximate to a front of a respective shoulder of the user. Each cuff is engaged to a first end of a respective band and is removably engageable to a respective wrist of the user. The bands draw the arms of the user toward the harness, thereby restricting movement and positioning of the arms to promote proper running form.

Apparatuses, systems, and methods of use are disclosed for enhancing upper body exercise. An apparatus includes a domed hand support section, the domed hand support section having a plurality of recesses configured to receive a palm, thumb, and fingers of a user's hand while the user's hand is held in a naturally curved open-position. The apparatus also includes a surface engagement section secured to an underside of the domed hand support section and configured to engage a supporting surface. When the surface engagement section is deployed on the supporting surface and the palm, thumb, and fingers of the user's hand are placed in the plurality recesses on the domed hand support section, the domed face supports the user's hand in the naturally curved open position while the user exerts force against the domed hand support section and that is at least partially directed toward the supporting surface.

A compact, portable, lightweight, easily transportable leg press exercise apparatus to simulate both exercise and the daily activity of sitting in a microgravity environment. The exercise portion of the apparatus creates stress on the lower extremities by supplying a variable resistance to a reciprocating foot pedal by way of a coil spring and damper system acting through a four-bar linkage. The chair is adjustable in angle to fit each user and to simulate a force that is two-thirds of body weight. By combining resistance exercise and lower body negative pressure with the LBNP leg press exercise apparatus, the users experience one or more times body weight (BW) in stress on their musculoskeletal, cardiovascular and nervous systems. By achieving one times BW or greater (artificial gravity) during exercise and two-thirds BW during sitting, the gap between the precondition and post condition syndrome will become smaller.

Full body exercise equipment including four elongate rails arranged in a generally side-by-side longitudinal configuration. The four elongate rails are connected together to allow for selected angular arrangements between the rails and also allow for selected longitudinal arrangements between the rails. A slidable shuttle member is provided on each rail with the two inside rails having toe holds and the two outside rails having hand grips. A resilient cord is provided for each shuttle for selectable attachment to either end of the shuttle to provide selected resistance against slidable movement of the shuttle in either direction on a respective rail.

An exercise system and an adjustment method thereof. The exercise system includes an exercise machine and a data transmission device. The exercise machine includes a control unit, a storage unit, a stepless force device, a sensor, a user operation part and an operation interface. During exercise, the control unit executes the exercise program to dynamically change resistance according to a sensed location, speed or acceleration of the user operation part and an adjustable parameter. Through the data transmission device, the user can download the personal training parameter from a remote device into the exercise machine, or upload the training result and the personal training parameter to the remote device.

A multifaceted exercise system is provided having several components, each capable of performing a different exercise. A vest worn by the exerciser has front segment and back segment, each segment having spaced apart O-rings and resistance bands secured by each O-ring adapted to be forced forward and laterally in order to exercise the chest. The back segment of the vest is provided with a panel member having roller receiving cavities each having fitted with a roller for performing a squatting exercise by moving the back panel member up and down a flat surface such as a wall. The back segment of the exercise device is also provided with a left O-ring and a right O-ring, a left resistance band having its upper end secured to the left O-ring and its lower end secured to the left foot, and a right resistance band having its upper end secured to the right O-ring and its lower end secured to the right foot. The exerciser can conduct abdominal exercises by removing the panel member from the back of the vest, placing it on a flat surface, and pushing and pulling the panel member using the hands of the exerciser.

A rear handlebar assembly in combination with a seat and a supporting member of a stationary bike, includes a seat of a stationary bike for supporting a rider thereon. A supporting member supports the seat of the stationary bike. A joining member includes a vertical bore and a horizontal bore, the vertical bore receiving therein the supporting member, the horizontal bore receiving therein a shaft coupled to flanges of the seat. A clasp holds the joining member against the supporting member. A crossbar forms a rear handlebar adapted to support the hands of a rider in an upright riding position. A rearwardly extending member connects the joining member to the crossbar. A pair of hand grips can be positioned on the crossbar.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.
