Abstract: A dual compound and isolated exercise machine includes a frame including a first portion and a second portion positioned in a plane generally perpendicular to the first portion. The spool line may be relocated to any leverage point on or near the frame. The spool assembly can be wirelessly controlled. Wireless signal sent to a wireless receiver activates a motor, gear reduction box, and variable speed drive to join the spool assembly, causing the release or retraction of the spool line. Tension along the spool line is measured by a force transducer and converted to readable real time measurements for display on a data monitor. The device is capable of producing and measuring maximum (0 to 100%) potential muscle concentric, isometric and concentric muscle contractions. The device is collapsible, portable and wheel chair and paraplegic accessible.

Abstract: An exercise machine includes a frame including a first portion and a second portion positioned in a plane generally perpendicular to the first portion. A carriage assembly moves along a linear path parallel to the first portion. A drive unit is joined to the frame for movement the carriage assembly in a first direction and a second direction. The drive unit includes a motor, a ball screw joined to the motor, and at least one support bearing rotatably joined to the ball screw and joined to the carriage assembly for enabling the carriage to move along the linear path in response to the ball screw rotating. A first sensor activates the motor in a first mode to move the carriage in the first direction. A second sensor activates the motor in a second mode to move the carriage in the second direction.
