They’re calling it a “revolution in double under technology.” And never before have we been this jacked about jump roping — not since Rocky 4 anyways, when Mr. Balboa trained like a maniac in a snowy warehouse in the middle of the woods for his fight against the infamous Ivan Drago.

Created using the latest in CAD and 3D modeling technology, ERC Apparel’s Ninja Speed Rope is the future of fitness. Not only was it initially developed from a UK engineering principle, but, before its release, it went through rigorous testing and observation.

We’re not sure who at ERC Apparel tested the product for hours on end, doing double and triple unders to experiment with speed, arc and accuracy, but, with its ABEC stainless steel bearings, CNC constructed components, nylon coated wire and, of course, its lightweight carbon fiber handles, we’re pretty sure it’s whoever the fittest guy — or gal — at the company is.

Designed to offer the ultimate in smooth and fast rotations, with an effort on reducing fatigue and improving consistency, it’s easy to see why this product has become a hot ticket item in our store.

Just don’t forget to add Hearts on Fire to your playlist before taking it for a spin.
