Practice...I practice a few times a week normally around 12 or 13 games in a session...sometimes get up to around 20. The idea is to work on all the elements of your game...focus on any fault you might notice whether it's not being able to consistently shoot 10 pins or if you've developed any unorthodox habits in your approach or release. The only way to make it anywhere bowling...to actually be a good bowler is to practice. Anyone can average over 200 on the THS, but that does not make them good bowlers. If you can do that on the sport shot or PBA conditions, then you're a real bowler. If someone couldn't hit an area of 10 to 15 boards consistently, they have no business even trying. Narrow that area down about 3 to 4 times and if you can hit that consistently...meaning maybe 3 to 4 boards tops, then you have some talent. Simply put, if you want to improve your game, practice and work on everything you can during that time...and throw a few serious games. Someone said you don't need to bowl until your arm hurts...I agree with that. Just bowl as much as you feel you're capable of. With time, your endurance should improve as well and you'll be able to handle more games at a time.
