Run from one side to the other at the shallow part of the pool (the deeper the water, the more drag or resistance you'll experience).
Place your hands on the pool edge, slightly over shoulder-width apart, brace your core, transfer your weight into your upper body so that your toes rise from the bottom.
Stand shoulder-width apart with toes turned out in the shallow end. Squat down with flat feet and seat back into your hips and heels.
Side shuffle over the shallow part of the pool. Maintain your core and toes facing forward.
Start in water that covers your feet. Lift your legs so your body is horizontal, maintaining your spine neutral from your head to your tailbone.
Brace your core and stretch your arms and kickboard forward against the water, then instantly draw them back into your chest.
Squat with flat feet and sit back into your hips and heels, then straighten your hips, knees, and ankles to drive through your balls and jump high.
