It's tough to beat the calorie burn from jumping rope, and now you can train and track at the same time. Tangram's Smart Rope combines form and function with comfortable 45 degree angled handles to help make this age old workout interesting. Sure, there are other smart ropes out there that provide tracking, but none of them have a strand of bright white LEDs that you can view while you jump. View your jump count, calories burned, or the duration of your workout as the rope swings in front of you. When you're done, the data is all transmitted via Bluetooth to an app on your smartphone. The only thing you have to supply is some sweat and an epic workout montage soundtrack.
