A dynamic belt tensioner for a treadmill includes a base having a first end and a second end spaced apart from the first end. The footrest platform is movably supported by the base to allow the platform to move vertically during operation of the treadmill. The belt has a fixed circumference and is positioned over a top portion of the platform. A drive roller is pivotally mounted adjacent the first end of the base and engages the drive belt. The tension roller is pivotally mounted to the base and is capable of a range of movement in response to vertical movement of the platform to provide a substantially constant tension to the drive belt.)
