Input:
If you can't get to the gym or are traveling, this is a great device to keep in shape. I like that you can quickly change the cables and increase or decrease the tension. The handles are comfortable to grip and the stretching action is smooth, providing ample resistance throughout movements. Unlike the old metal-spring cables, a tubing exppander can easily be packed in a travel bag. You can find more than a dozen movements by searching the Web or you can invent your own routines. I also like that with an expander you can hit the majority of muscles, even the legs. Eventually, you'll have to replace the cables, so inspect them before using to make sure there are no cracks or other damage. Go for it!
