An exercise machine with an adjustable safety tier and rack out hook system, having: (a) a safety tier attached to and moveable along each of a pair of upwardly-extending guide rods, wherein the safety tier can be rotated to a locked position such that the safety tier latches onto the upwardly-extending support member or rotated to an unlocked position; (b) a counterweight connected to each safety tier; and (c) a rack out hook attached to and moveable along each of the upwardly-extending guide rods, wherein the rack out hook can be rotated to a locked position such that the rack out hook latches onto the upwardly-extending support member or rotated to an unlocked position.

An exercise apparatus with base horizontal members forming a base polygon and ceiling horizontal members forming a ceiling polygon and a plurality of vertical members mounted at their lower ends to the base polygon and mounting the ceiling polygon spaced from the base polygon. A human interface permits athletes to exercise, and wheels mounted to the base polygon permit transport of the apparatus and attached equipment to a field or court. The base polygon includes two parallel skids and the human interface may be a pad permitting an athlete to push the apparatus horizontally when none or two of the wheels contact the ground. When no wheels contact the ground, the apparatus may be used in the manner of a weight rack, because the apparatus will not move along the ground without substantial force being applied.

A system for promoting knee flexion may comprise a support bar and a plurality of pads removably mounted thereto, such that sequential use of the plurality of pads may progressively allow a knee joint to move through an increased range of motion.

A retractable wall mounted exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The retractable wall mounted exercise rack system generally includes one or more brackets attached to a wall, a pair of support members, and a plurality of arms pivotally extending from the brackets and pivotally connecting to the support members. One or more actuators are connected between the brackets and the arms to assist in lifting the structure into a compact retracted position for storage.

The invention relates to a method, an exercise device and a software for measuring maximum muscle strength value. Wherein, the method for measuring the maximum muscle strength value through an exercise device with dynamically variable resistance signal-connected to an arithmetic control unit, is obtained by performing the following steps. The steps include: an obtaining original muscle strength value step, an initial muscle strength value generation step and a maximum muscle strength value generation step. The characteristic of the present invention is that the maximum muscle strength value is obtained according to the position of the exercise process, which overcomes the shortcoming of traditional technology that can only obtain a single data. Moreover, the present invention further forms a maximum muscle strength curve, whereby the obtained data can be used in fitness training to effectively improve training effects and avoid muscle injuries caused by overloading.

A patient aid assembly includes an upper extremity support assembly and a housing associated therewith. The housing slidingly engages a rail and allows relative movements therealong. First and second upper extremity support assemblies are received on first and second rails, respectively. An interconnecting member us hingedly connected to each of first and second housings that support the UE support assemblies.

Weight lifting strap which is looped around the wrist and wrapped in helical fashion about a weight lifting bar or the like and gripped by the hand with opposite sides of the strap facing the bar and the hand, and the strap being fabricated of a woven material with rubberized strands on the side of the strap which faces the bar.

Patient aid devices and an associated method of supporting an upper extremity are described and include a mobile upper extremity support for the patient. A support assembly supports a first side of an upper body of the user for movement along a first rail. The support assembly also allows motion of a second side of an upper body relative to the first side.
