In order to learn the yo-yo release in bowling, learning how to clear the thumb out of the bowling ball first is the most difficult part as a beginner.
As a bowler, we want to squeeze and we don't quite understand proper feel yet as we are still getting accustomed to fundamentals such as setup, footwork, swing, timing, etc.
Through the no step/foul line drill and 1 step drill, bowlers are able to isolate and focus on the release itself, establish a better understanding, and integrate it into their full approach as they learn.
As your release improves, your strength and technique will get better and you'll start to incorporate more elbow bend and forearm to be able to generate a higher rev rate like PBA bowlers.
