<p>An exercise machine (10) is described which is entirely self-contained without any source of outside power. A rechargeable battery (56) is used to maintain the exercise system operative for a time-out period. At all other times the machine is powered by the user. The machine is compact, light, rigid and sized to fit through a standard doorway. The entire exercise machine is provided with a wrap-around handrail (88) into which a display input/output unit (31) has been integrally provided. The exercise machine or stepper utilizes a dynamically controllable load or alternator (14) which is controlled by a computer circuit (30) to maintain the power input into the exercise machine or to maintain metabolically energy consumption rate within a user of the exercise machine at a predetermined, approximately constant level, regardless of the speed of stepping or the actual or effective weight of the user.</p> |
