An inclination drive mechanism for a treadmill permits driven, selective adjustment of the angle of inclination of the treadmill. The drive mechanism includes an electric motor which operates through a gear train including an output gear pinion. The gear pinion in turn drives a gear rack, which can be provided in either a linear or arcuate configuration. The mechanism includes a load-bearing support bracket on which the gear rack is mounted with the support bracket configured to minimize non-torsional loading of the gear train. The resultant construction is desirable economical and durable.
