A range of motion limiting device, in one example comprising a first armature configured to engage a carriage moving on at least one rail having a first surface and a second surface transversely offset from the first surface of the rail. Also disclosed is an example utilizing a first bumper adjacent the first longitudinal end of the first armature. The first bumper extending transversely from the first transverse side of the first armature, optionally having a distal end with a non-slip surface engaging the first surface of a rail. Also disclosed is a second bumper longitudinally offset from the first bumper on the first armature, the second bumper extending transversely from the second transverse side of the first armature, also optionally having a distal end with a non-slip surface engaging the second surface of the rail.

A system and method for optimizing a person's muscle group performance thru modulating the arm, leg, and core muscle exertion rate based upon the exerciser's metabolic and geographic data. The system uses real-time measurement gathering and storing of physiologic parameters from humans during physical exercise activity and the geographic data of the exercise activity to determine information for optimizing the exerciser's physical exercise performance of the basic working muscle groups in the rider's arms, legs, and core. The system broadcasts to exercisers information including, but are not limited to: a) the current condition of their monitored muscle tissue, b) which muscle groups the riders should modulate and change their level of energy output during the exercise activity, and c) level of energy exertion at which riders should be employing at that moment in the relevant working muscle groups to optimize their physical exercise performance.

An interactive exercise system includes a mechanical support system and a display module held by the mechanical support system. A force-controlled motor is attached to the mechanical support system and a reel is driven by the force-controlled motor. The interactive exercise system also has a handle graspable by a user and includes a cord extending between the reel and the handle. The handle or other accessory can be attached by a quick release mechanism. Force applied through the force-controlled motor is based at least in part on detected user force input.

The disclosed inventive concept provides an orthopedic exercise apparatus for accommodating a wheelchair-bound user and allowing the user to perform low-load prolonged stretching without getting out of his or her existing wheelchair. The apparatus includes a base having a top sheet and a bottom sheet secured thereto, and a T-shaped structure mounted to and extending perpendicular to the base. The T-shaped structure includes a stabilization post having an adjustable height and a cross-bar mounted to the top end of the stabilization post. The cross-bar is lowered onto the user's thighs in order to limit stretching to the user's knee or provide passive a dorsiflexion force to the ankle. The apparatus can be used in conjunction with a pulleyed weight station for treating knee flexion contractures or, alternatively, with a pair of ankle blocks removably fitted within the base for treating ankle plantar flexion contractures.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

The power squat exercise machine is an exercise machine for performing a squat exercise in a safe and controlled manner by providing shoulder pads with a specific angle which allows for the optimal comfort, posture, safety, and transfer of strength to a free weight squat. Support members are provided for more stability to the machine. It provides a dual safety stopping mechanism. The stopping mechanism provides controlled movement by the user and a safe entry and exit from the squat exercise machine. An adjustable safety locking mechanism is also provided which allows the user to control the movement range of the resistance.
