Stairmill climbing is also considerably more beneficial than forms of step up down exercise, as it greatly reduces stress on the joints, especially knees. The joint loading in stepping down is approximately 2 1/2 times that in stepping up. This low impact, non jarring cardio-respiratory workout facilitates increased oxygen intake and improves muscle strength and bone density.
