Oh, I cant jump a rope worth a good god-damn. But, avoiding developing the real coordination and conditioning by buying a rope-less jump rope isnt the answer. Practice is the answer. Altho I suppose someone could argue that jumping over that piece of rope isnt the goal here, doing the exercise is the goal. And whether you are jumping up and down over a piece of rope or jump a virtual rope doesnt matter....and this gizmo gives you counts and other feedback, But, then again, you can cheat in your "jumping" with this thing and not really perform as you would if you had to avoid getting tangled up in the rope.
But it looks foolish as hell.
