See how it dangles, put it on the surface edge to make me 10 good jumps back.

Does it hurt or did you get used to it now?
If you are used to it compliment, replace with the weight of 2kg, but if it still hurts go on with that from 1kg.

10 more jumps back, after each jump let it dangle until it stops.
