A therapeutic rehabilitation device utilizing two parallel independent foot pedals on one side of the device, for isolated ankle exercises, and a larger flat board on the other side of the device, large enough for two feet to rest on, for use in active assistance exercises. To use the device for active assistance rehabilitation, the user places the device on the ground with the two pedals resting on the ground. To use the device for active isolated exercise, the user flips the device over, with the flat board facing the ground, and the two pedals facing upward.

In one aspect of the present exercise machine, an assembly is attached to the end of a reformer, where the assembly comprises a seat mechanism and a pedal mechanism. The seat mechanism has a seat, a bracket supporting the seat, and a height adjustment system, where activation of the height adjustment system permits selective adjustment and locking of the height of the seat and the bracket by restricting travel of the seat and bracket to a slanted path that is slanted relative to the vertical. The pedal mechanism has an axle, a first pedal arm with a first pedal, and a second pedal arm with a second pedal. The pedal mechanism is located directly beneath the seat when the seat mechanism is in a lowest position and partially exposed in a higher position.

An exercise device is provided that replicates on dry land the movement and resistance of a paddling motion. The exercise device includes a hollow upper shaft, a handle connected to an upper end of the upper shaft, and a lower shaft coupled at least partially within the upper shaft by a spring, to allow retraction into and extension from the upper shaft. The exercise device further includes a blade replacement assembly connected with a bottom end of the lower shaft, the blade replacement assembly comprising one or more wheels connected with a bottom end of the lower shaft and a resistance mechanism to provide resistance against a rolling direction of the one or more wheels.

An exercise device for attachment to an exercise machine or as an independent stand alone exercise device that includes an enclosure having an outer wall that defines an internal space therein, at least one cable aperture and an attachment mechanism for attaching to the exercise machine. A winding assembly is rotationally captured within the internal space and includes a winding spool configured for receiving at least one cable wound there around under resistance provided by a motor. The motor is used in conjunction with a controller circuit, a power source, and a user interface. To perform exercises with the exercise device, a person sets a desired cable unwind resistance with the user interface and then repeatedly pulls and retracts the at least one cable.

A multi-axial unidirectional power transmission system includes a transmission unit and a resistance unit. The transmission unit includes a first main shaft and a transmission wheel provided on the first main shaft. The resistance unit includes a second main shaft and a damping wheel mounted on the second main shaft. The two transmission wheels and the damping wheel can be placed flat on the body since they are mounted on different main shafts, thereby making the whole plane of the multi-axis unidirectional power transmission system consistent, thus achieving the effects of space saving, convenient storage and convenient transportation.

Disclosed herein is exercise equipment for strengthening the pelvis, by which the exercise effect of enabling the pelvis, the genitourinary sphincter inside the pelvic cavity, etc. to be strongly contacted and relaxed may be obtained during the exercise of collecting and spreading the knees. The exercise equipment includes: grip parts (110); cylindrical insertion/separation pipes (120); cylindrical support pipes (130); packing parts (140); cylindrical cushion parts (150); side fastening U-shaped plates (160); fastening plate supports (170); a side support connection bar (180); and fastening belts (200). Rotating grips (190) are attached to the bottoms of coupling bolts (B), respectively, by which the side support connection bar (180) connects and fastens the side fastening U-shaped plate supports (170), and the side support connection bar (180) is fastened to the bottom of the cushion part of a chair by using the two fastening belts (200) and coupling bolts (B).

The system of the present invention includes elastic bands that are affixed and inserted within elastic band insertion slots that are disposed on a u-shaped frame and a rectangular-shaped frame. The squatting motion the user performs on the present invention activates the expansion and retraction of the elastic bands, which exerts resisting force upon the user, simulating weights.

A piece of exercise equipment particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a core support, a guide arm, a head support, and a foot support that work in conjunction to most optimally support the user. The core support, the head support and the foot support are all connected, supported, and elevated from the floor by a central support system.

To perform exercises with the exercise device, a person sets a desired cable unwind resistance with the user interface and then repeatedly pulls and retracts at least one cable.

The present invention applies to the field of exercise devices and bodybuilding and muscle building devices. This invention describes a system applied in exercise devices, preferably for the performance of the activity of bodybuilding, without the use of a counterweight, in which the system is based on the speed of the movement, independent of the applied force.
