Explosive power is super important for any athlete that has to quickly change direction, jump, or dodge (so basically any athlete). This is why Moltzan's trainers have her do plyometric exercises, moves where both feet are off the ground at the same time.
To do this box jump, line up two boxes (or steps) with the tallest one first and the shorter one several feet after it. Starting from two feet, jump up onto the first box, landing with both feet. Immediately spring off the box onto the ground and then hop up onto the second box. Jump off the second box and, for true skiing effect, add in some lateral hops as soon as you hit the ground. That's one rep. Do 5 reps total.
Training tip: To start, your highest box should be no taller than knee height. Once you get the movement down, you can use taller boxes.
