* Experiment with different ball sizes to see which one works best for you. Most pros use a 15lb ball. * A good rule of thumb is to choose a ball that’s about 10 percent of your bodyweight (up to 16lbs). * Chose a ball with finger holes that fit your fingers. * Aim for the space between the first and third pin if you’re right handed or between the first and second pins if you’re left handed. This space is known as the pocket. * Learn to throw a hook. You’re more likely to bowl a strike when the ball travels toward the pins in a curve. * Develop a consistent approach to each shot. The more similar your deliver, the more likely you are to replicate the same shot each frame. * Keep your wrist of your bowling hand braced throughout your shot. * Pay attention to where your hand is on the ball. If you release in the center of the ball, the ball will go straight. If you release with your hand off-centered, the bowling ball will hook away from your hand.
