An exercise bar assembly includes a pair of rotating grip assemblies, each including a generally planar frame and a hand grip mounted within the frame for rotation within in the plane of the frame. The rotating grip assemblies are attachable to opposite ends of a center bar assembly along the longitudinal axis of the bar assembly. A plate bar assembly is attachable to each of the rotating grip assemblies opposite the center rod, with the plate bar assembly aligned with the longitudinal axis to form a weight lifting bar. A user-selectable elastic band is engageable between the pair of rotating grip assemblies along the longitudinal axis so that the elastic band resists rotation of each hand grip in each of the rotating grip assemblies. The rotating grip assemblies of the exercise bar assembly allow for the full range of motion of the bicep, and the elastic band creates a resistance exercise through the bicep's full range of motion.

The present invention provides a modular cable-based resistance workout device that can be used in different types of indoor and outdoor settings such as platform mountings, wall tracks, doors, trees, poles, or benches or chairs. The workout device includes a left spring plate assembly, a right spring plate assembly, a mainframe, a shaft, a cable reel, and a platform, or a wall mounted track or ratchet straps. The each of the spring plate assembly includes a permanent resistance assembly and a plurality of variable resistance assemblies. Each of the variable resistance assemblies comprises a secondary recoil spring that is selectively engageable with the shaft. The permanent resistance assembly alone or along with the selectively engageable plurality of variable resistance assemblies resist unwinding of the cable from the cable reel upon application of pull force on the cable.

A multi-purpose exercise bench having a versatile resistance accessory configurable for use to provide weight-training resistance in a variety of exercises is provided. The multi-purpose exercise bench comprises: an elongated frame configured to rest on a flat floor in a stable manner; a lower seat portion supported on the frame; the resistance accessory mounted to the frame, the resistance accessory comprising: a pad movably mounted to the frame to be movable between a first position and a second position; a locking mechanism operable to lock the pad in either of the first position and the second position; and a plurality of resistance bands attached to the pad. A multi-purpose exercise system includes the multi-purpose exercise bench and an exercise bar defining at least one groove dimensioned to receive at least one receiver ring attached to at least one of the resistance bands.

A waist fitness apparatus includes main body and a resilient cover. The main body has a base pivotally connected with a supporting board through an eccentric unit, and the base is used to distribute the weight of the user, so the main body can be stably disposed on the ground. The present invention is advantageous because the height of the supporting board is higher than the height of the knee height of an average adult, the user does not have to bend the knees when sitting on it to increase the comfortableness. Also, the supporting board can be dragged back to its original position by the cover when it is not in use, so the user does not have to adjust the supporting board.

In one example, a muscle exercise device includes a first arm, and a second arm rotatably connected to the first arm, and the second arm and first arm are movable to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the arms.

A back strengthening and therapy device has a frame with two body encircling frame members, each frame member having a front end and a rear end. A handle is located on the front end of each of the frame members and a back impacting element is located at the rear end of each frame member. An expandable, cross member interconnects the frame members. When this cross member is locked, the user can conveniently position the back impacting elements on his or her back and apply selected pressure to the back by manipulating the handles and the back impacting elements. When this cross member is unlocked, allowing the elastic to expand, the user can pull backward, creating resistance, in a repeated motion, for purposes of strengthening the back.

Disclosed is a fitness device mounted in a vehicle seat, the device configured to provide a passenger with various exercise effects during long distance traveling of an automotive vehicle and to relieve boredom and muscle fatigue caused by lack of body movement, and including a seatback having opposite side portions to which armrests are rotatably mounted, respectively, at least two belt entry and exit devices mounted within an internal space in the seatback, each of the belt entry exit devices being configured to allow a belt to be pulled out from and introduced into the seatback, and a handle portion detachably mounted to a front end portion of the armrest and to which the belt pulled out from each of the belt entry and exit devices is connected by passing through the inside of each of the armrests.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.

A method for treating pronator syndrome involves selecting an arm and positioning it with the forearm perpendicular to the upper arm. The hand of the arm is engaged with a grip located inside a bisected working circle, which has an outer perimeter consisting of four quadrants. The fourth quadrant is elliptical and asymmetrical to the others. The grip is designed for hand engagement and includes two d-shaped slots. A resistance band is attached to the body, with one end in the groove, creating tension when used. To exercise the arm, the body is rotated in one direction to increase tension on the band. Releasing tension is achieved by rotating the body in the opposite direction.
