STEP 3: Do the Pump
Once you're set, quickly turn your torso to the right and pump your arms. This simple move stretches the key downswing muscles just as much as a traditional backswing, giving you the same amount of potential energy to unleash into the ball. Think of how a frog squats before leaping, ratcheting up his elastic energy to explode into the air.
As you do it, make sure you:
• Turn your shoulders to a full 90 degrees.
• Pull the majority of your weight onto your right hip.
• Move your left arm across your shoulders, not up into the air. You want coil, not lift.
