Keeping a free arm swing increases your accuracy, consistency, power, and more control
“Rolling” the ball knocks down more pins than “throwing” the ball. Envision sitting on the floor and rolling a ball to a small child. Bowling balls are made to react to the lanes, rolling the ball allows the ball to do the work as it was made to do
Timing. Think of timing in a 4 step approach. The hand and the foot on the same side as the ball are the synchronizing gears that should mesh (move together) early in the approach. The ball should move with the foot (right foot for a right handed bowler). As you take your 1st step the ball moves (your push away) with that step. The ball should follow the foot back behind the body on the 2nd step. This allows the ball to clear the hip on its backward motion. This is where many bowlers are confused. Many bowlers do not have the ball follow the ball side foot back behind them. They will keep the ball in front of the body too long (push away on the 2nd step) and as the ball goes back, the foot on the same side as the ball is already in its forward motion.
In a 5 step approach the ball does not move on the 1st step.
Hold your position at the line until the ball leaves the pin deck.
This does not mean that you should look like the Statue of Liberty, but that all of your body is still after you have delivered the ball, EXCEPT your bowling arm. It is swinging back and forth and will eventually stop without your help
