发明名称 Spontaneous symmetrical weight shifting device
摘要 A stationary exercise device, comprising a frame member having a transverse pivot axis. A first and a second foot tread member are operatively associated with a coupling member for pivotally coupling the first end of each foot tread member to the pivot axis at a predetermined distance from the pivot axis, so that each foot tread member first end travels in an arcuate path about the pivot axis. Each foot tread member moves independently of the other foot tread member. Each foot tread member second end is operatively associated with a glide member for moveable coupling of the second end of each foot tread member to a support surface. The glide members direct each foot tread member second end along a reciprocating path of travel, as each foot tread member first end travels in an arcuate path.
