A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

The disclosure discloses a strength training equipment. The strength training equipment includes a speed changing device, which includes a driving motor and a speed changer, wherein the speed changer outputs the output of the driving motor after speed reduction; a differential mechanism, which is provided with a first output shaft and a second output shaft and can convert the output after speed changing by the speed changer into asymmetric force to be output from the first output shaft and the second output shaft; and a take-up device, which includes two take-up boxes which are connected with the first output shaft and the second output shaft respectively.

A weighted-squat exercise machine comprises a pivotable, length-adjustable lever, a weight supported by said lever, a support base, and a hip-belt that connects a user to the machine. Weights are supported by the machine at a safe distance from a user. The weighted-lever has an angle with respect to the horizon with a range of from about 35 degrees to about 45 degrees. When a user wearing the hip-belt connects it to the weighted-lever, the weight's gravitational force is transferred to the user providing for the user to perform weighted squats in a safe manner as the weights are spaced from the user. Thus, athletes can safety exercise without a spotter even if using 1000 pound weights. The belt supports the weight about the athlete's hip structure so that there is no stress on the user's neck and spine and no restriction in breathing.

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.

An abdominal exercising apparatus should allow the user to strengthen their abdominal and oblique muscles in a comfortable manner. The present invention seeks to strengthen the stomach muscles and do so in a comfortable manner that allows the user of the invention to exercise in an upright seated position, while also providing a massage of the user's back muscles along each side of their spine. The present invention can be used on a bench, chair, couch, or other seating apparatus where it can be used in comfort and while engaged in other passive activities, such as, watching TV. An added benefit of the present invention is that it provides massaging of the muscles on both sides of the user's spine as it is used.

A training sled apparatus, comprising: a platform with a rear edge and a wedge shaped front edge, opposite the rear edge of the platform; and, at least one sleeve provided to the platform and configured for placing a training component therein

A bar or tube with two slots on each side configured to accept a flat or round elastic exercise band or cord; wherein said slots may be rounded along the edges so as not to tear or slice at the elastic exercise band or cord. The elastic exercise band or cord may be tied into knots or bulges on either end and such knots may be inserted into the slots of the bar making it ready for use. The bar may also comprise adapters to adjust the size of the slots to different sizes of flat elastic bands or cords. The invention may also comprise a rubber roller which may be made to house a vibrating unit, said housing unit may be turned on by a switch when held to the body.

A modular home gym can include a platform with one or more holes that mate with one or more mating portions of attachable and removable exercise attachments. A variety of exercise attachments can be connected to the platform in a variety of configurations. Other embodiments are described.

In accordance with the invention, a uniquely constructed, lightweight calf raise exercise device is provided which is user friendly, portable, and inexpensive—providing athletes with the ability to effectively strengthen leg muscles without going to the gym, which is optimal for the busy lifestyle. The calf raise device generally includes a platform assembly having a length extending between a front side and a rear side, the platform assembly including a first surface extending a segment of the length from the front side and an elevated second surface extending the remainder of the length between the first surface and the rear side, wherein the first surface is configured to support the user's heels during operation and the second surface is configured to support the user's toes during operation and throughout the motion of the calf raise. The calf raise device also includes at least two ankle cuffs configured to receive the ankles of the user wearing the calf raise device and at least two elastic resistance members operably connecting the platform assembly with the at least two ankle cuffs respectively. The elastic resistance members are configured to provide resistance throughout the motion of the calf raise.

A resilient rod that provides adjustable directional resistance is disclosed. In one aspect of the invention, a resistance level may be determined based on a thickness of the rod and a position of an applied force with respect to a fulcrum point. In another aspect of the invention, at least one spine may be attached to the beam to increase a diameter of the beam along one axis. The resistance level may be determined based on the thickness of the rod, the position of the applied force and an orientation of the at least one spine with regard to the direction of the applied force. In other aspects of the invention, the resilient rods may be incorporated into a golf club that provides for adjustable resistance levels.
