Patent ID: 8025611

Claim:
An exercise apparatus for exercising a user's arms and legs comprising: a frame for residing on a horizontal surface; a pair of arm-supporting members for supporting the user's arms; a pair of leg-supporting members for supporting the user's legs; a linkage assembly for coupling the arm-supporting members and leg-supporting members to the frame and for moving the arm-supporting members and leg-supporting members in closed paths relative to the frame in response to forces the user applies to the arm-supporting members and leg-supporting members, wherein the linkage assembly comprises at least one actuator, each actuator for adjusting a dimension of at least one of the closed paths in response to a control signal; a sensor coupled to the linkage assembly for generating a force-indicating signal representing a user force applied to at least one of the arm-supporting and leg-supporting members; and a user interface for receiving the force-indicating signal, generating the control signal from the force-indicating signal, and supplying the control signal to each actuator.
