The magnetic resistance assembly includes two magnetoresistive rings disposed respectively on the two fan wheels and around the axle, a magnetic unit and a controlling unit. The magnetic unit includes two magnetic portions respectively corresponding to the two magnetoresistive rings. The controlling unit includes a lever rotatably disposed on the main body at a pivot point, and the magnetic unit and an operating portion are disposed on the lever and located by two opposite sides with respect to the pivot point. The pivot point and the axle are eccentrically arranged.

A device and method for influencing the movement and muscular function in the neck, includes a helmet, the helmet has a rim, said rim has notches along the edge, on top of the helmet there is attached a vertical rod, on top of this vertical rod there is attached at least two laser sights pointing forward, at least one rod is attached at one end to the vertical rod, and the at least one rod can rotate around the vertical rod.

A multiple position adjustable exercise device includes a first plate, a second plate and an elastic member. The second plate is pivotally connected with the first plate. The elastic member is disposed between the first plate and the second plate, and when the second plate rotates relative to the first plate, the elastic member is twisted for providing an elastic recovering force. An initial position of the second plate relative to the first plate is adjustable for adjusting the elastic recovering force.

The present invention relates to a hand gripper including a first arm, a second arm, a pair of spring members, a first spring member coupling shaft, and a second spring member coupling shaft, wherein a plurality of first elastic force adjusting grooves and a plurality of second elastic force adjusting grooves, to which the first spring member coupling shaft and the second spring member coupling shaft are selectively coupled, respectively, to adjust strength of elastic force provided by the spring members, are formed in a first body of the first arm and a second body of the second arm, respectively.

An exercise system has an elongate rigid housing, and an elongate extension arm mounted via a pivot to a bottom end of the elongate rigid housing. A first pulley system is rotatably mounted to a fixed position of the elongate rigid housing. An adjustable mounting mechanism is mounted on the elongate rigid housing. A second pulley system is rotatably mounted on the adjustable mounting mechanism so that the second pulley system can be moved relative to the first pulley system, thereby adjusting the distance between the first pulley system and the second pulley system. An elastic cord extends back and forth between the first and second pulley systems, around the arm pulley of the elongate extension arm, and to a free end that may be used for performing exercises.

A spring-grip easy to adjust grip, comprising a torsional spring and two handles for inserting torsion arms of the torsional spring, wherein spacing blind holes are punched on the torsion arm; the handles comprise a fixed handle, a movable handle, a collar, a spring and a limit steel ball, the fixed handle and the movable handle are both hollow tubular structures, compared to the prior art, the invention is provided with different inner diameter segments in the movable handle to realize the limit steel ball having two states of tension and looseness in truncated-cone through hole, thereby realizing the torsion arm having two states of fixation or movable adjustment in handles, which makes grip adjustment method easier, simultaneously, spacing blind holes are labeled with different grip values, which can intuitively determine the grip when using different spacing blind holes, and scientifically guide the grip exercise.

An exercise apparatus includes a support frame unit, a crank wheel unit disposed on the support frame unit, a resistance unit for providing resistance to the crank wheel unit, and two link units respectively disposed on left and right sides of the support frame unit. Each link unit includes a first pivot arm pivotally connected to the support frame unit, a pedal rod pivotally connected to the first pivot arm, a second pivot arm pivotally connected between the support frame unit and the pedal rod, a drive rod pivotally connected between the first pivot arm and the crank wheel unit, and a foot plate disposed on the pedal rod.

Provided is a hand grip including a first and second operating arms capable of moving toward and away from each other, a first and second connection arms disposed between the first and second operating arms to be inclined, of which both ends rotatably connected to the first and second operating arms, a spring member installed to provide an elastic force in a direction interfering with approach of the first and second operating arms, a spring fixing part formed to extend upward from the first operating arm and to which one end of the spring member is fixed, a spring connection part formed to extend from an upper end of the first connection arm and to which the other end of the spring member is fixed, and a strength adjusting part formed in the spring connection part and configured to allow the other end of the spring member to move.
