The duvide Barjumprope offers four ways to jump: hands-free, single-hand, double-overhand and regular grip.
To use it without hands it needs to be strapped to the waist and rotated by hip movements (like the hula hoop, only vertical). This makes it a demanding core workout but also benefits the waistline. If used as a regular jump rope, it helps to develop upper body strength due to the strong pull of the weighted hoses, similar to a heavy jump rope.
It is also fun rope to play around with and test out new techniques never done before.
