This machine was the mainstay for recovery after a total knee replacement. Having my own proved to be cheaper than the PT bills. This is a piece of equipment that offers varying degrees of resistance from light to heavy resistance to increase the stretching and workout. The handrails offer a good upper body workout and cardio. Now that I back on a normal gaite, selling this for less than half of what I paid for it. This machine would be a good workout tool for anyone who is more dedicated to working out and exercising. Asking $450.00.
