You're lying to yourself and me as well if you can say that you don't like jumping rope. Simple, cheap, hard to mess up, and just plain fun — it's totally an exercise I can trick myself into doing.
Maybe you haven't done it in a few years, but let me remind you: It rocks. The LED Jumplay rocks even more — it counts and displays your revolutions!
Feel accomplished for yourself or a trainer if you're jumping to get in shape, or if you're jumping for fun, how much more fun (and geeky) could it get than this? What do you think of it? Awesome fitness/fun gadget, or over-complicating a simple tool with technology?
