A fitness device comprises a force applicator comprising: a base; a first fixed wheel comprising a first center pivotally fixed to the base, and configured to allow rotation of the first fixed wheel about the first center; a second fixed wheel comprising a second center pivotally fixed to the base, and configured to allow rotation of the second fixed wheel about the second center, wherein the second fixed wheel is substantially in line with the first fixed wheel; and a movable wheel positioned above and between the first fixed wheel and the second fixed wheel, and comprising a movable center configured to move either toward, or away from, the first fixed wheel and the second fixed wheel, and is configured to allow rotation of the movable wheel about the movable center; an elastic element, placed between the nut and the fixing element, and a rope configured to be accommodated in the force applicator. Additional embodiments of the fitness device are disclosed herein.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

Assisted racking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining completion of the exercise based at least in part on the detected state of the cable. It further includes selectively removing resistance from the cable based at least in part on the determination that the user has completed the exercise.

An actuator and an exercise equipment using the same are disclosed. The exercise equipment comprises a post which is a main body of the exercise equipment, a shoulder installed on an upper side of the post and rotates in left and right direction, an arm combined with the shoulder and rotates in up and down direction, a hand combined with one terminal of the arm and rotates by using the arm as an axis, a handle located on one terminal side of the hand, a force control actuator outputs a force corresponding to weight set by a user, and a wire passes via plural sheaves included in the hand, the shoulder and the post and deliver a force generated by pulling of the handle, one terminal of the wire being connected to the handle.

A portable rehab station includes a frame having left and right frame members that have bottom ends; left and right outriggers, each having a forward end and a rearward end, the left and right outriggers being connected at the bottom ends of the respective left and right frame members; a front, ground-engageable caster connected to the forward end of each of the left and right outriggers and a rear, ground-engageable caster connected to the rearward end of each of the left and right outriggers; and a standing assist apparatus including a leg brace and connection means for variably connecting the leg brace to the frame members and at variable heights relative to the bottom ends of the frame members.
