Whether you want to learn how to spin a ball or curve it during delivery to your opponent, you should seek professional guidance on how to do it right. Some people have a natural aptitude for delivering a ball that can stump the opponent. However, for the most part this is something that is learnt through hours of practice so that muscle memory kicks in when the time comes to throw a ball that has the potential to turn the tide of the game. Ensure that you are doing it right and that muscle memory retention is developed for the multiple methods of bowling.
Practice is the key to success in order to become a successful bowler. If you don’t practice you will not allow the muscles that are required to fulfils the needs of specific bowling methods to kick in and do their jobs when you send the message from your brain as to the intended effect you want to have on the ball. Find a wall and practice bowling towards it. Work out how the ball bounces off the wall depending on the amount of spin you put on the ball. Work out how to get the ball to bounce in the direction that you want it too. All of this requires a well defined technique that can only be acquired through trial and error.
Ask a professional in the field about how to best hold the ball to get the effect that you want. It may be a matter of using the correct grip or wrist action in order to get the ball to work the way you want. It is important that you realize how physics comes into play. Although a professional may not be a physics graduate, they will have an understanding of the concepts that are required to enable a ball to work the way you intend.
