A device and methods for performing a closed-chain exercise for the lower extremities of a human subject and, in particular, the legs, using stimulation. The device may include a sled for receiving the subject and for translating to and fro between a first, lower position in which the legs are at least partially bent and a second, higher position in which the legs are less bent than in the first position. A stimulator is provided for facilitating the performance of the closed-chain leg exercise by the subject to move the sled between the first and second positions, either by way of electrical signals provided directly to the applicable muscles or by way of sensory (e.g., visual) stimulation, with or without electro-muscular stimulation. In another aspect, adaptive feed-forward control may also be used to enhance the exercise regimen performed using the device.

A pair of horizontal pivotable rowing arms and second pivotable vertical arms pivot on oil hydraulic motion resistance wedges attached to an underside of a desk.

The machine can be collapsed for transport and re-assembled without the use of tools.

The present invention discloses a method and an apparatus of counting steps for a treadmill. The method measures a load exerted on the treadmill and detects the number of instant loads caused by a user applying a force by the user's legs for each time of the exercise to count the steps of leg exercise during an exercise. The treadmill includes a treadmill body, a load detection unit, a display unit, and a base of the treadmill. The base has a motor and a treadmill belt, and the load detection unit is provided for detecting the load exerted on the motor and recording the number of instant loads of the motor, and the display unit is electrically connected to the load detection unit for outputting the number of loads of the motor.

A hand and foot lever-arm rowing type exercise device is mounted in the leg space under a desk or cubicle work surface. A resistance device such as a spring, rubberized cord, air cylinder, attaches between the pivotally attached adjustable lever arms and the desk. Hand grips twist and have tension arms for gripping exercises as well as moving the lever arm for full arm exercises. Foot straps on a foot board and bicycle pedals enable leg exercises.

An isolation exercise machine for exercising one muscle group has a user support which is pivotally mounted on a main frame by a pivotal mounting system. A user engaging exercise arm is pivotally connected to the user support, and a connecting link links movement of the user exercise arm to movement in the user support. A load provides resistance to movement of the user support, exercise arm and/or connecting link. The pivotal mounting system is configured to place the user support seat in a relatively flat position in the rest or exercise start position and to recline and change the seat angle to an inclined position as the exercise arm is moved.
