Abstract
To support a deck of an exercise treadmill one or more arcuate leaf springs are used in a deck support structure. The leaf springs can be made of a single member of elastomeric material. An adjustment mechanism can be used to change the radius of the leaf springs in order to vary spring rates of the leaf springs. Where a number of different leaf springs are used, the adjustment mechanism can be used to adjust the spring rates of different springs independently.
