When was the last time you jumped rope? Unless you’re training as an extra for the next Rocky movie, chances are that a song probably went along to the cadence of your jumps. If you’ve got kids, you may have joined them in a game — and been embarrassed by how quickly you got out of breath. Jumping rope is indeed excellent exercise, and the Tangram Smart Rope Pure is a top-of-the-line jump rope with bells and whistles that you could have only dreamed of as a kid.

The rope synchs to your smartphone to help you keep track of the number of jumps, calories burned and time jumped. You can even design interval workouts around the rope. Two sets of ball bearings in each handle help the lightweight rope (or, more accurately, a cable) move smoothly over and around your body, and the 45-hour battery life means you’ll be jumping for months before you need to recharge. The rope is adjustable, so you can ensure that it’s just the right length for comfort.
