Resist device for stationary exercise device

Abstract

A stationary exercise device includes a support device for cyclically and elliptically supporting two foot supports above a base, and a resist device coupled between the foot support and the support device for applying a resistive force to the foot support and for braking an elliptical movement of the foot support relative to the support device, the resist device includes two members slidably coupled together and moveable linearly relative to each other for applying a frictional and resistive force between the members and for resisting a linear movement between the members, and for resisting the elliptical movement of the foot support relative to the support device.
