Abstract
A treadmill includes a frame; a plurality of bearings coupled to the frame; a running belt at least partially supported by the plurality of bearings and adapted for rotational movement relative to the frame, the running belt having a running surface, at least a portion of which is curved; a braking system configured to selectively resist rotation of the running belt; 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.
