been a year or so ago some of us were talking about a machine called a Nu-Step we used in rehab, but they were like over 3 thousand for one. tonight I bought a thing that you push with your feet and got the arms workout too, for 2 hundred. It's a body by jake machine. but when I get it put togather I willl post a picture for others to see. I sat down on it at the store for a bit and it will give you a workout, and you can adjust the tension. It's the closest I've come across to the nu-step just not near as big and fancy but it does the same kind of excersise, and it's cheap!!!!!!
