Some kind of massage thing or a virtual jump rope? Or maybe... Is this that VR controller that can shift its weight around to give feedback on, like, a ball and chain?
The image doesn't even look real. It looks like a 3D rendering.
Edit: Just read the rest of the comments. It is a jump rope thing?! Is it meant for VR or something? Why not just use an actual rope unless you can't swing it over your head? ๐ค
