Abstract
An exercise treadmill with a deck retention system including a frame with a deck supported resiliently on the frame. A continuous belt having an upper run over the deck and a lower run under the deck is driven by a roller connected to a motor. A glide surface is connected to the frame in contact with a front and/or rear edge of the deck. At least one roller can be connected to the frame and emplaced in contact with the edge of the deck to restrict longitudinal movement of the deck between the glide surface and the roller. Alternatively, instead of the roller a second glide surface in contact with the edge of the deck opposite from the first glide surface, or a second roller can be placed to allow up and down movement of the deck between the rollers and/or the plastic glide surfaces while restricting longitudinal movement.
