Welcome the tech future of home fitness. SmartRope is an LED-embedded jump rope that displays your fitness data in mid-air as you work out. Think of a film or animated movie scene depicting one flash of quick motion: the LEDs fire at different times as the SmartRope rotates around you, creating the appearance of a single display floating in mid-air during your workout. This gadget pairs with the Smart Gym app on iPhone, iPad, and Apple Watch to help you exercise smarter.
