Jump

I just heard about the new cordless jump rope. It’s supposed to help clumsy people from tripping on the rope. It definitely sounds like a solution to the problem, but I’m wondering what a “jump rope” should be called without the rope. Just “jump”? But then if you only pretend to jump over the pretend rope, you don’t even need to jump. So if there’s no rope and no jump, what should it be called?
