Smart Rope Jump Rope
Jumping rope is one of the best ways to burn calories, and now you can train and track at the same time with this smart rope. The rope combines form and function with comfortable 45 degree angled handles to help make this age-old workout more interesting. Other ropes on the market provide tracking, but none have a strand of bright white LEDs that are visible while you're jumping. View jump counts, calories burned, or the duration of your workout as the rope swings in front of you. All the data is then transmitted via Bluetooth to a smartphone app — meaning all you have to supply is some sweat and an epic workout soundtrack.
