A centering device includes a receiving bracket configured to be attached to a bench unit including at least one wheel, the receiving bracket defines a receiving hole, and a catch mechanism configured to be attached to an exercise machine, the catch mechanism comprising at least one outer peg and a center peg, the outer peg defining a groove. The receiving bracket and wheels being engagable with the catch mechanism to center the bench unit with respect to the exercise machine.

A weight machine sensor includes a force sensor, a position sensor, and a processor. The force sensor is programmed to output a force signal representing a force applied to a pulley-disposed on a cable incorporated into exercise equipment having a stack of weights. The position sensor is programmed to detect motion of the stack of weights and output a position signal representing the motion detected. The processor is programmed to receive the force signal and the rotation signal and determine, from the force signal and the position signal, exercise data including an amount of exercise resistance and a number of repetitions performed.

A machine for concurrently or independently performing pressing motions with the hands and feet, the machine having a base having front and back ends, two or more linear slide rails, a lower body user support with an engagement means for the user's feet and an upper body user support with an engagement means for the user's hands. The upper body user support and lower body user support slide on the linear rails that are located proximally on opposing ends of the base frame and the upper body user supports and the lower body user supports cooperate with one another to move in opposing converging and diverging sloping linear movement patterns during operation of the machine.

In a method of strengthening pathological muscles, the patient is subjected to a therapeutic strengthening exercise for strengthening a target muscle. The method begins at the start of the strengthening exercise in response to exacerbation of symptoms exhibited by patient. The symptoms exhibited by the patient during the strengthening exercise are minimized by a series of steps including adjusting an intensity of the strengthening exercise, limiting a range of motion of the strengthening exercise, dividing evenly a prescribed number of sets and repetitions corresponding to the strengthening exercise, dividing unevenly the prescribed number of sets and repetitions corresponding to the strengthening exercise, varying a speed at which the patient is subjected to the strengthening exercise, modifying a position of the patient for the strengthening exercise, matching a mode of the strengthening exercise to the modified patient's position, and switching between primary, secondary and tertiary actions of the patient's target muscle.

A training or exercise apparatus may have a base and an adjacent movable armature or frame that carries a riding member, or shuttle, or carrier. The carrier has an engagement interface with an element of sporting or exercise equipment. The sporting or exercise equipment is engaged by the user, typically by being grasped. The apparatus defines a physical or virtual schedule describing an arc for a swing in the particular activity. The apparatus may include a manual or electronic means of imposing resistance to the motion. This resistance may be adjustable, and may be programmable as a function of one or both of position and speed. The apparatus may include an array of sensors such as may be used to determine the pre-existing stroke, and such as may be monitored during training to assess progress. The apparatus may be operated passively, or it may be operated interactively in a manner in which real-time feedback causes the apparatus to adjust resistance to the motion.

An exercise machine may include a tower enclosing, at least in part, a cable and pulley system, a base supporting the tower on a surface, and a plurality of handles operatively coupled to the cable and pulley system and configured to extend from the tower. The exercise machine may include a resistance motor operatively coupled to the cable and pulley system. The resistance motor may include a fan and a flywheel connected to a common shaft. The exercise machine may be operatively associated with a user interface which includes an exercise display area configured to activate one or more exercise indicators in a predetermined sequence and a control area including at least one mode control operable to change the sequence of activation of the one or more exercise indicators. The user interface may be provided on a console of the exercise machine.

A weight training apparatus includes a telescoping pivot arm comprised of a concentric arrangement of an outer tube and an inner tube and configured to pivot about an axis and receive a weight at a predetermined position. The weight training apparatus further includes an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis. The weight training apparatus further includes a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis and a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile.

An electricity generating system using fitness equipment, wherein the fitness equipment can be used to produce electricity with a generator. The electricity produced can be transferred from the generator to a splitter. A controller can be used to receive identifications and decisions on transfer of the produced electricity from a fitness center. The controller can be used to track in real time electricity produced as watts or as amperage associated with a user identification, a fitness class identification, or an administrator identification input less than 10 minutes before the electricity is produced or at a preset time, which can then transfer in real time energy credits equivalent to electricity produced or transfer produced electricity to a destination designed in the a user decision, a fitness class decision, or an administrator decision.

A gymnastics apparatus, comprising an at least semicircular arc structure which is adapted to define a pair of rails along which at least one body can move on which at least one cable can be unwound and wound, in contrast with a resistance, said cable being adapted to be gripped by a user who positions himself or herself proximate to the at least semicircular arc structure.

A portable exercise system that can be attached to the uprights on any commonly available training rig, squat stand, or power rack, and for resistance can use any attachable weight. The system includes an upper pulley assembly, a lower pulley assembly and an anchor assembly. The anchor assembly utilizes a wedge and block to set the cable length and is adapted to attach the weights. The upper pulley assembly includes pulleys to keep the cable aligned and the resistance coming from above. The lower pulley assembly could be hinged for an additional degree of freedom. The cable runs through the lower pulleys, to the upper pulleys, and down to the anchor and weights. The other end of the cable has a fixed loop for attaching a handle for the user.
