Your non-bowling arm is almost as important as your bowling one. It helps provide balance. Your non-bowling hand and arm come off the ball at the end of the push off and should go out to the side of your body to help offset the extra weight you have on the bowling side of your body. If you don’t get that arm out to the side for balance, you’ll tend to fall off the shot. Having this arm even with your body or slightly behind your torso with your hand waist high or higher and about 18″ or so from your body will provide the counter-balance you need. ‘Textbook’ says not behind your body. Tell this to WRW Jr. or to Carolyn Dorin-Ballard, both of whom have their non-bowling arm about 90º to their back at the finish position. Do what works!
Another very important component of the non-bowling arm is the position of the thumb. If your thumb is up at delivery, there could be a tendency to roll the shoulder forward. It is usually more effective to have the thumb down. Check which one you do and then try it the other way. You will find turning the thumb up or down can give you some options you didn’t know you had!
