I am thinking of getting a resistance tube with handles to do some dry land toning of my legs & arms to help tone and lose fat better (toned muscle burns more fat right?) How do I know whether to get a "light", "medium", or "heavy" resistance? I typically swim 4000-4500m per workout, if that matters. I am thinking medium.
Here are the choices:
Heavy www.swimoutlet.com/.../15424.htm
Medium www.swimoutlet.com/.../15423.htm
Light www.swimoutlet.com/.../15422.htm
