A ryhthmic motion driver for exercise, having a case (11) containing a moveable flywheel assembly (12), an engagement track (25) along which the flywheels move linearly while rotating, and bearings that guide the assembly along another track (16) on the case (11). An opposing spring within the case compresses and expands creating oscillatory motion of a bar attached to the assembly, the bar extending through an opening in the case. The rhythmic motion driver stores and releases energy to impart slow rhythmic motion to the body in any desired direction.
