Summarize the following:
In fast-pitch softball, when you start moving your body forward in any capacity after you've touched the pitcher's mound, this is considered the start of the pitch. You then have to move towards delivering the pitch for the pitch to be legal. After rocking back on your heels, transfer your weight forward by reaching both your arms forward, pointing towards the catcher and home plate. This will help build even more momentum for your pitch. This is often referred to as a "superman" pose. To finish building momentum for your pitch, swing the arm with the ball back up over your head and down into your backswing. Keep your gloved hand forward to help guide your aim. As your arm swings up and back, your weight will naturally transfer to your back foot. Right when your throwing arm hits the top of your backswing, swing your arm down past your hip and in front of your body to throw the ball towards the catcher. As your throwing arm swings forward, shift your bodyweight forward by pushing off with your back foot and stepping out in front of the plate. As your arm swings in front of your body, try to keep your shoulders as level and keep your head as still as possible. This will help you throw the ball faster and more accurately. As you swing your throwing arm forward, release the ball right when your hand passes by your hip. Your throwing arm will be pointing down at an angle with your palm facing out towards the catcher. If you release the ball too early, it will travel at an angle towards the ground near home plate. If you release it too late, it will likely go too high in the air. Therefore, it's important that you practice to get a feel for the exact moment you need to release the ball to get it to travel straight to the catcher at the fastest possible speed. After you release the ball, make sure the you let your arm follow through with the swing on its natural course. Your arm should continue to swing up to your chest. This will ensure that you let your arm gain the maximum amount of momentum and that you throw the softball with the maximum amount of speed. Following through with your swing will also help you avoid putting any extra strain on your muscles from an immediate, abrupt stop.
