The rope is made from a tough and extremely durable yet very flexible kink-free coated cable that does not coil up. The handle is designed to turn the rope extremely fast allowing you to progress with double and triple unders. This high speed crossfit jump rope will make crossing moves, double unders, and even triple unders easier and fun. The cable can be easily adjusted from the maximum length of 10 feet, allowing you to get a personalized length by adjusting a couple of screw. To size the jump rope properly, find the middle of the rope and place it under your right foot. Hold the rope up to your right armpit. Where the top of your pectoral meets the rope is the proper length for your jump rope. Adjust the screws on each handle and slide them to that portion of the rope. Tighten the screws. Tip for double unders: Keep your hands slightly in front of your hips. Keep your elbows tuck in to your sides. Perfect for beginners as well as advanced jumpers.
