Abstract
An elliptical machine includes a foot link having a portion resting on an angled member such as a ramp secured to a frame. A wheel may mount to the bottom of the foot link and rest on the ramp. An end of the foot link pivotably connects to a sliding link, the other end of which is connected to an angled guide secured to the frame. The sliding link is coupled to a crank rigidly connected to a flywheel. A swinging arm pivotably connects to the frame and has its lower end pivotably connected to swinging arm link. A handle secures to the swinging arm above the point of pivotal securement to the frame. The swinging arm link secures to the sliding link at the same point as the crank.
