An exercise apparatus has a linkage assembly which links rotation of a crank to generally elliptical movement of a foot supporting member. The crank rotates about a crank axis relative to a frame, and a distal portion of a link moves relative to a connection point on the frame. An intermediate portion of the link is rotatably connected to the crank, and an opposite distal portion of the link is rotatably connected to a rearward end of the foot supporting member. An opposite, forward end of the foot supporting member is movably connected to the frame.
