Abstract
A treadmill with an adjustable cushioning mechanism configured to adjustably cushion the impact to a user who is exercising on the treadmill. The adjustable cushioning members allow the user to select the amount of cushioning that will be provided while the user is exercising on the treadmill by adjusting the cushioning members to individualize the amount of cushioning for a specific user as well as for a particular type of exercises. The treadmill comprises a frame and an endless belt trained on the frame. The belt has an upwardly exposed exercise section. A deck is disposed between the exercise section of the belt and the frame. The treadmill also comprises a plurality of cushioning members each having a plurality of portions with different cushioning properties. The cushioning members are positioned on opposing sides of the frame. The cushioning members are mechanically interconnected such that movement of one of the cushioning members results in corresponding movement of the other of the cushioning members. The cushioning members are configured to be adjusted so as to selectively position a portion of the cushioning members between the frame and the deck. An adjustable flexible cantilever is disclosed that comprises an arm and a bumper. The arm has one end mounted to the frame and the other end freely disposed from the frame. The bumper extends between the free end of the arm and the deck. A brace mounted to the frame adjacent to the cantilever that can be selectively moved along the length of the cantilever.
