Abstract
An exercise treadmill (10) includes a main frame (12) on which is mounted an endless belt (14) trained over a forward drive roller (16) and a rearward idler roller (18) both axled on the main frame. A deck (20) closely underlies and supports the upper run of the endless belt. A subframe (22) is pivotally mounted on the forward position of the main frame 12 adjacent the front of the deck (20) to pivot relative to the main frame about the same transverse axis (24) about which the drive roller is powered by an electric motor (28) mounted on the subframe (22). The orientation of subframe (22) relative to the main frame is selectively alterable through a linear actuator (26) which may be controlled while standing on the treadmill deck (20).
