Use the correct weight ball for your size.
Choose the heaviest ball you can throw without compromising your ability to have a full, relaxed arm swing, good speed, and not cause you to lose balance or drop the ball early. A good rule of thumb to follow is to roll 1 pound of ball per 10 pounds of body weight, then add or subtract 1 pound. For example, if you weigh 120 pounds start with a 12 pound ball. It may seem to heavy at first, but as long as you have a full, relaxed arm swing, good speed, and it doesn’t cause you to lose balance or drop the ball early stick with it. If not, go up or down in weight accordingly.
Use the lane to help you aim.
When you stand on the approach ready to begin your shot, as you look at the lane you will notice a variety of markings. About 15 feet down the lane there are a series of arrows that point toward the pins. Most bowlers look at these arrows rather than the pins when aiming. Why? Simply stated, it is easier to hit a target that is closer to you. So, begin bowling and watch your ball roll over the arrows, ensuring you are standing in the same position to start each time–use the dots on the front of the lane to position your feet. Make a mental note of where the ball crossed the arrows when you hit the head pin. This will be your “mark”. Beginners should practice this method with the first ball of each frame first, it gets a bit more technical when trying to get spares.
Don’t worry about strikes.
No one gets a strike every time. If you put that kind of pressure on yourself you won’t have any fun. I always thought that was the idea behind playing games-have some fun! Focusing on technique will help you to improve. Once you develop the mark mentioned in tip #2, make sure that you actually watch your ball roll over it every time. If you hit it and the result is consistently different, consider developing another mark. Strikes will come, work on your technique and get those spares; you’ll find that a few strikes will sneak in there after a while.
