The follow-through is one of the most important ingredients in a successful bowling style. It’s fundamental, but yet, often forgotten. While a casual observer might be thinking that the follow through is overrated, since the ball has already left the hand, there’s actually much more to it than just that. The follow through is almost like the controller for the entire delivery, even though it’s out of the immediate equation. The follow through is the aftermath of a well-delivered ball.
There have been tips that say that you should essentially be ‘shaking hands’ with the headpin (or your target pin). That’s a good tip. However, with the follow-through, if your hand is in a position in which it’s in direct line with your target pin, that means that your armswing is straight toward your target. So, you’ve done your job properly with it comes to bringing your arm on a direct line.
However, it should be remembered that the follow through isn’t responsible for the release of the ball, but rather it’s more of a confirmation that you’ve at least executed the most basic part of your game properly, and that would be the use of your arm to propel the ball forward.
