Query: You get a work out

This is a great product to use at home that allows you to get a quick work out in without moving all of the furniture. You are basically marching in place. It is quick paced so you do get in a good work out. Even my kids (6 & 3) join in for a little exercise. We use soup cans for weights instead of the weighted balls.
