Abstract
An exercise apparatus which promotes cardiovascular exercise yet provides minimal impact on critical joints. A base structure is provided which supports a pair of reciprocating members that are displaced in a generally reciprocating manner at one end yet orbit at the other end through a coupler assembly attached to the frame. The coupler assembly includes a mechanism to variably adjust the radius of the arcuate motion while the device is in use. A structure is included which permits each foot of the user to move in a generally closed path during the exercise. By being able to continuously variably adjust the size of the orbit, the user can fine tune the height and length of the closed path which redefines the foot motion to a preferred path for the anatomy of the particular user.
