Abstract: A stair climbing machine includes a plurality of steps connected, via a drive assembly, to, the frame of the machine to move in a closed loop path which brings each step to a position near the ground to provide a low step-on height. The drive assembly may optionally be supported on a movable portion of the frame to allow the incline of the closed loop path to be selectively varied to adjust the vertical distance between adjacent steps of the machine.

Abstract: A lateral glide stationary elliptical exercise device (10) with foot support platform (90) yaw control. Yaw control is achieved by a four bar dual rocker linkage yaw control mechanism that includes (i) a foot link (70) with a pair of laterally offset first (p5) and second (p9) connection points constrained to move through generally elliptical paths within parasagittal planes, (ii) a glide link (80) pivotably connected at a first end to the first connection point (p5), (iii) a drawbar (100) pivotably connected at a first end to the second connection point (p9), and (iv) a foot support platform (90) pivotably connected proximate a second end of the glide link (80) and proximate a second end of the drawbar (100).
