Ask any professional athlete and they will tell you that skipping is one of the best forms of cardio. The Tangram Smart Rope is here to help you take it up a level. This gadget displays your fitness data in mid-air via a clever LED light display on the rope itself; the LEDs fire at different times as the Smart Rope rotates around you, creating the appearance of a single floating display during your workout. It is also able to store data to help you stay at the top of your game.
