A treadmill includes a frame, an exercise deck attached to the frame, and a first handle movably attached to the frame. The first handle has a first orientation where the first handle is positioned within a region above the exercise deck and stabilized to support a user's weight during a body weight exercise, and a second orientation where the first handle is positioned away from the region above the exercise deck.

A body weight exercise device includes a frame, a first handle attached to the frame, a second handle attached to the frame, and a processor and memory. The memory includes programmed instructions to cause the processor to determine a characteristic associated with a performance of an exercise with the body weight exercise device.

The invention discloses an elasticity adjusting mechanism of an exercise equipment which includes a base, a staggered frame, an adjusting socket, an elastic body and force exerting member. The base and the staggered frame pivot with each other and constitute the main structure of the elasticity adjusting mechanism of the exercise equipment. The staggered frame extends outwardly from the base and includes an extended socket and a plurality of fixed portions, the fixed portions are disposed on the staggered frame and with different distances to the extended socket. When the adjusting socket is selectively assembled with one of the fixed portions at different positions, the elastic body passing through the extended socket and the adjusting socket changes its elasticity in accordance with extension amount.

An elastic structure of a sport equipment comprises a base, a staggered frame, an elastic body and an applying member. The base is supported on a ground. The elastic body is extendable and retractable located on the base. The applying member is connected to the elastic body for generating a stretching movement back and forth. The base and the staggered frame can be foldable, thus the elastic structure of the sport equipment has a smaller volume for collecting and saving.

The invention provides an apparatus, system and method for reducing the size of portable rotary motion exercise devices. Flexible materials in contact with the user or a piece of furniture is part of the connection between the user and the exercise device. Multiple wraps of a band around a shaft provide adjustable rotational resistance.
