This is my third set of StrechCordz. The first one was a bit too soft. It worked for many exercises, but in some rooms I had to stretch them very far to get enough resistance. The second and third are identical - one for home and one for my suitcase. These will exercise all upper body muscles. The only thing you have to do is find a sturdy connection point. In hotels, that is almost always the door handle leading to the hallway. I got rid of my cable-weight machine because these take up less space and work just as well. I mostly use them for rows, overhead presses (lean forward and press away from the anchor position). I prefer the Charles Atlas dynamic tension exercises (no equipment) for bicep/tricep (although StrechCordz can work these muscles too), and one-leg squats for quads/gluts. I also used these for swim pulls and close grip pulldowns when I was doing triathlons (4 consecutive Kona qualifications).
