Spontaneous symmetrical weight shifting device

A stationary exercise device comprising;

• (a) a frame member having a pivot axle disposed transversely relative to the frame member;
• (b) a first and a second foot tread member each tread member having a first end and a second end, each foot tread member first end operatively associated with a coupling member for pivotally coupling the first end of each foot tread member to the a respective transverse pivot axle at a predetermined distance from the transverse pivot axle, so that each foot tread member first end travels in an arcuate path about the a respective transverse pivot axle, wherein each foot tread member moves independently of the other foot tread member, and each foot tread member second end moves in a linear reciprocating associated is operatively associated with a glide member for moveable coupling of the second end of each foot tread member to a support surface, to direct each foot tread member second end along a linear reciprocating path of travel as each foot tread member first end travels in an arcuate path.
