There are a few ways to get better at bowling that is not hard to do. The best way to get better at bowling, is to just go bowling and practice. You can’t get better without going to the bowling alley and rolling the bowling ball down the lane. It’s ok to just go bowling to just bowl. You go bowling and work on the things that you can’t do, the things that you are weak in like getting the 10 pin. Work on things to make your game different.
So if you bowl straight or down and in, try sliding left from your target if you are right handed. Try to hook the ball more, try a different hand position, try shooting at spares. Come to practice with a purpose of trying new things.
The one thing that you can do is watch the PBA on TV. I watch the PBA to see how the pro bowlers are bowling, the line or target that they play, the bowling ball that they use and how they pick up spares. How the pro bowlers move their target and when they move, I see how they handle when the lane change. Watching the PBA on TV is a great way to learn and see how to bowl better.
