Whenever a technique is lacking in speed or power, most athletes are quick to pick up on weaknesses lower or upper-body strength, as they begin to work pull-ups, push-ups, squats, etc. If you have a slow cat-leap top out, the first thing you think is lack of pull-power, so you start to do insane amounts of pull-ups, ignoring the fact that a top out is a full-body technique that relies on a stable core to transfer force from your torso outwards. When your vaults are lacking in either speed or distance, the first weakness people can usually spot is a lack of power from the initial leap, yet this might make surprisingly little difference in the overall power of these techniques. The initial momentum is purely reliant on the commitment of your approach, and then your ability to transfer this momentum effectively mid-vault takes precedence. In this way, your lower-body power might matter less than your overall core stability in the attempt to maximize the explosiveness of your vaults...
