This is a quick bowling tip, The first tip is to practice your target system which is shooting at a target on the floor over and over again. Try shooting at different targets and angles.
The second tip is to move away from your comfort zone and try something total different. There will come a time where you have to total change the way you bowl, and total change the way you think. So if you learn different styles or different ways or something that you are not use to than you will be better off. Bowling all angles on the bowling floor is the best that to have under your belt.
