Abstract

A computer controlled exercise machine, particularly adapted for running exercises, virtually eliminates inertial effects and controls resistance to pushing and pulling as a function of instantaneous position in a stroke and/or instantaneous velocity, using the controlled flow of working fluid through computer-controlled valves and sensors of various system parameters in a feedback loop.
