All of the jumping, none of the tripping! Double-dutch your legs off like a Harlem schoolgirl without the neighbors seeing!
It’s a patent on nothing, my, oh my!
“To use the invention, a user holds a handle in each hand, and begins to simulate jumping rope while moving the handles in a circle with their hands and arms. The weighted ball or gear simulates the centrifugal action of a jump rope, thus delivering all the health benefits of jumping rope without any of the disadvantages of stumbling on the rope, having the rope hit the ceiling or the like.”
