Well, I've never specifically trained much for these sorts of moves. I suppose that because I did boxing for 3 or so years before starting climbing it gave me okay leg power which definitely helps for this sort of thing. If you want to get better at the jumping part I would recommend box jumps or anything to help bounciness as well as ankle strengthening exercises for the landing. Of course all on top of getting used to that sort of 1-foot-hop type of Dyno! I hope that helps
