A wrist exerciser includes a housing and a gyroscopic member. The housing includes a first cover, a second cover, a supporting portion and a protective assembly. The supporting portion and the protective assembly are disposed between the first cover and the second cover. Two ends of the supporting portion that are opposite to each other are in contact with the first cover and the second cover, respectively. A stiffness of the supporting portion is greater than a stiffness of the protective assembly. The protective assembly includes a rail and a buffer portion that are corresponding to each other. The gyroscopic member includes a ring and a rotor. The ring is slidably disposed on the rail. The rotor includes a ball disposed in the housing and a shaft which penetrates the ball. Two ends of the shaft that are opposite to each other are pivotally connected to the ring.

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.

A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

A handheld resistance exercise device is contemplated for exercise, rehabilitation, warm-up and the like, which provides resistance to muscles, tendons, joints, and fasciae in the upper body and lower back as it is actuated by a user standing a distance away from a vertical surface that is engaged with the device. Actuation thereof by the user in performing various exercise protocols provides stability for one or more muscles of the hand, elbow, shoulder girdle, shoulder blade, rib cage, as well as the inner core muscles, while also providing improved mobility for one or more of the wrist, forearm, elbow, shoulder joint, and muscles that rotate and bend the spine sideways.

A wrist exerciser including a housing and a gyroscopic member is disclosed. The housing has a rail and a buffer portion. The position of the buffer portion corresponds to the rail. The gyroscopic member is moveably disposed on the rail, and includes a ring and a rotor. The ring is located inside the housing and is slidably disposed on the rail. The rotor includes a ball and a shaft. The ball is located inside the housing. The shaft penetrates through the ball and the two opposite sides of the shaft are connected to the ring for the shaft to rotate relatively to the ring.

A sports wrist trainer comprising a first elongated swing member with grip attached to a second elongated swing member with head by means of a one way 90 degree hinge, and an elastic return means that returns and holds said swing members at a ninety degree angle one to the other. According to alternative embodiments, the wrist trainer is a bat used for learning batting swings or a golf club used for learning golf swings. The one way hinge rotates to provide a trainer having different swing configurations and to maintain the bat or club head facing the ball at impact just like at address. The elastic return means may be removed and the trainer used without it. A second one way 90 degree rotating hinge can be added to the first providing additional versatility and accommodating both right and left handed golfers.
