No need to keep count: SmartRope PURE does the work for you, using the tech built into the jump rope to accurately track your jumps, recording each revolution and syncing the data to the corresponding Smart Gym app on your phone. The handles have ball bearings built-in (along with an innovative 45-degree rope housing), which means you get the best grip, the smoothest feel, and the widest range of motion as you jump. A built-in LED shows when you’ve paired successfully, and when your battery is low (charge it for just two hours, and get 45 hours of active use). SmartRope PURE also features an adjustable rope length, fully customizable to your height and preferred jump stance. It’s a light, fast, higher-tech way to work out.
