Abstract:
An elliptical exercise device includes a frame having a first pivot axis and a longitudinal axis, at least one foot link and at least one swing arm. The foot link is coupled to the frame and is constrained to move in an orbital path approximately parallel to the longitudinal axis. The swing arm is also coupled to the frame and has a reciprocating movement whereby a natural “stride” movement of the arm of a user is replicated. The swing arm operates independently from the foot link. The natural “stride” movement of the arm of the user grasping the arm link follows a generally concave motion relative to the ground. The length of the movement of the arm of the user is defined by the user. A different resistive load can be applied on the arm apparatus than on the foot links.
