Patent ID: 8109861

Claim:
An exercise device, comprising: a frame; a first upper leg link and a second upper leg link, each pivotally coupled to the frame; a first lower leg link directly pivotally coupled to the first upper leg link and a second lower leg link directly pivotally coupled to the second upper leg link, each lower leg link including a foot support; a first transfer system movably coupled to the frame and including a first transfer member coupled to the first upper leg link and a second transfer member coupled to the second upper leg link; and a second transfer system movably coupled to the frame and including an alpha transfer member pivotally coupled to the first lower leg link and a beta transfer member pivotally coupled to the second lower leg link, wherein the second transfer system is (i) physically separate and operably independent from the upper leg links and the first transfer system, (ii) operable for transferring compressive forces and tensile forces between the lower leg links, and (iii) operable for effecting correlated movement of the lower leg links irrespective of movement of the upper leg links.
