Do you ever find yourself wondering how much kinetic energy you’re expending while working out? Of course you don’t, you’re too busy eying up that blonde on the treadmill in a Puma tracksuit. Well, now there’s a way of showing just how much of that good stuff you’re putting out with these brand new luminescent jump ropes.

These devices convert the kinetic energy you create from exercising into electric energy. This powers two LED lights at the end of the skipping rope in case you jump rope on a dark road and need to light your way (and who doesn’t do that?). There’s even a little display to let you know how many watts per skip you’re putting out luminescent jump rope. Neat.
