  • Exercise machine
    Patent number: 6371892
    Abstract: Exercising is made more comfortable and effective by providing a foot rest that has a front end which holds the ball of the user's foot fixed and a back end that both cradles the user's heel and allows the user to pivot his heel around the ball of his foot in a natural manner. The frame of the machine can be easily and repeatedly taken apart and put back together because it has two arms which mate at a connector that can be mated and unmated by simple pivoting of the two arms.
