>>131437 >jump rope doesnt go well on the knees.
That depends on the surface you jump rope on, the type of footware you wear, the intensity with which you jump rope, and your form.
These things determine how much your knees absorb shock from the impact of jumping up and down. If you jump barefoot on concrete for twenty minutes at a high intensity, your knees will probably suffer more than if you were to jump rope on a wood (see basketball) floor wearing a good pair of sport socks, and tennis shoes while maintaining good form (using your wrists to revolve the rope, keeping your jumps low, and bending your knees slightly) at a lower intensity.
>How long should I jump-rope for? If you're jumping rope for cardio, you need to keep your intensity low, and consistent. Initially, you need to pay the most attention to your form. After that, I'd suggest that you start with small intervals of jumping rope and work your toward longer intervals.
>Look up double unders I do these. I'm working on triples, but I don't quite have them mastered yet. You know of any more challenging moves?
