Abstract
A treadmill includes a frame; a front running belt pulley; a rear running belt pulley; a plurality of bearings coupled to the frame; a running belt at least partially supported by at least one of the front running belt pulley and the rear running belt pulley, the running belt including a running surface, at least a portion of which is curved; a support element coupled to the frame; and a safety device coupled to the running belt. The safety device is at least partly supported by the support element. The running belt freely rotates in a first direction of rotation relative to the frame, however, in a second direction of rotation, opposite the first direction of rotation, engagement between the support element and at least a portion of the safety device substantially prevents rotation the running belt relative to the frame.
