The present disclosure relates generally to exercise equipment for enabling a user to vary the effective muscle tension during the course of the performance of an exercise and, more particularly, to an exercise system for shifting an optimum length of peak muscle tension. In some embodiments, the system is an apparatus which comprises a force-generating element, e.g. a fluid cylinder, a user-input element which a user forcibly moves during the course of performance of an exercise, and also a coupling means, which is preferably a cable-pulley system, which transfers forces between the force-generating element and the user-input element. Finally, the apparatus comprises a control unit which controls and varies the level of force generated by the force-generating element during the course of performance of the exercise. The apparatus effectively varies the effective muscle tension through the generation of forces.

A hand and finger exerciser apparatus having a base unit structure, resiliently-biased slidable finger button devices, a movable thumb button device rotatably connected to the base unit structure, and a mechanism for selectively locking and unlocking the finger button devices. Each finger button device can be used independently to exercise fingers, or compress the entire unit for complete hand and forearm strengthening.

The present application is directed to a flotation device for use in aquatic physical therapy. The flotation device preferably comprises side portions that wholly or partly surround the user, and permit the user's elbow(s) and/or forearms to rest upon and be supported thereby. The flotation device also preferably has at least one handgrip permitting the user to easily hold onto and be supported by the flotation device. Additionally, the present invention comprises methods of making and using such a flotation device.

The present device generally relates to a portable and configurable exercise apparatus. The apparatus has a main aim unit and a removable foot unit. The main arm unit has a first hand grip and a second hand grip separated by a main telescoping shaft wherein pulling the first grip away from the second grip requires resistance and, therein develops strength. The device is configurable so as to allow the user to select the desired resistance. The removable foot unit may be temporarily inserted over the first or the second hand grip so that a user may place his/her feet (either standing, sitting or squatting) over the first or second hand grip and may pull upward with the remaining hand grip to exercise alternative muscles. The first and the second hand grip may rotate with respect to the main body shaft to allow alternative exercises.

Disclosed is a bike simulator including: a base frame; a slope frame rotatably connected to the base frame so as to apply a tilting back and forth to a seated bike; a roll frame fixing a frame of the bike seated on the slope frame and rotatably connected to the slope frame so as to apply a horizontal slope to the bike; and a rear wheel support provided in the slope frame, supporting a rear wheel of the seated bike, and including a load generating unit configured to control rotary force transferred to the rear wheel. In the bike simulator according to the present invention, a bike which an actual user possesses can be fixed and applied, and as a result, the user can feel an extreme realistic traveling sense.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine adjustable resistance system and method generally includes a control unit in communication with a resistance adjustment system of an exercise machine and a biometric monitoring device used by an exerciser on the exercise machine. The control unit receives biometric data from the biometric monitoring device and sends a control signal to the resistance adjustment system to adjust the resistance of the exercise machine based on the biometric data received.

An apparatus for human exercise in certain configurations includes first and second foot pads attached to first and second guided carrier members, respectively. A first curved guide rail portion is coupled to the first guided carrier member, and prevents motion of the first guided carrier member except for translation along the first curved guide rail portion. A second curved guide rail portion is coupled to the second guided carrier member, and prevents motion of the second guided carrier member except for translation along the second curved guide rail portion. A first motion resistor is coupled to the first foot pad and opposes a translation of the first foot pad along the first curved guide rail portion. Each of the first curved guide rail portion and the second curved guide rail portion is curved away from an underlying ground plane, to define a distally increasing rail height.

A mouth-opening training device includes a water-filled bag having a zigzag edge or a sawtooth edge. By increasing or decreasing the amount of water located inside the water-filled bag to alter the total thickness of the water-filled bag, said device can accommodate different thickness of occlusion of teeth of a patient. Said device can make a further improvement on layers of flavor in occlusion of the teeth. Said device can further include a plurality of pivotable plate-shaped objects connected or coupled to the water-filled bag. The plate-shaped objects can provide different thickness combinations and further meet the user demands on thickness of occlusion of the teeth.

A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank arm extending away from a rotational axis of the crank wheel, and a pedal beam connected to the crank arm. A linkage assembly is connected to the frame at a fixed frame location and to the pedal beam at a fixed pedal beam location. A first linkage member of the linkage assembly has a length that forces the pedal beam to travel along an elliptical path as the crank wheel rotates.

A Pilates Aquatics Device (PAD) including a board, the board being generally rectangular, planar, buoyant, and having top and bottom surfaces, first and second sides that are generally parallel to one another with a longitudinal axis midway there between, first and second ends generally perpendicular to the longitudinal axis, and a strap defining three loops on the top surface of the board, the loops aligned along the axis, the loops defining openings perpendicular to the axis for insertion of a user's hands or feet to control the PAD.
