I went for about 10 years without throwing any warm-up balls before leagues, I was young and in shape, a few stretches was all I needed. I rarely practiced, I was too busy doing other things.....

Now fast forward and I throw balls in warm-up and stretch to try and get loosened up. I also try to go and practice once a week or so, I throw a game of first ball 10 pins then usually throw 3 , usually trying to learn to throw different lines, speeds, and hand positions.

I was invited to come "practice" at a buddies open league session, it's a walk in league costs only 8.00 dollars and he's there coaching. He's a bronze coach and is over 70 and still averaging 215 , might be a good way to improve my game.
