Query: Super workout!

I have had these for a week and I must say they give me a terrific workout. Just follow the suggested directions and you alone can determine the extent of your fitness programWay better than a normal speed walk and much preferable to jogging which is hard on the knees and joints. I am 71 and lifetime fitness person, so I appreciate this approach. Email the supplier and let him know your height, then go ahead and order a pair.
