Consistency of the arm swing is one of the critical factors that a bowler needs to be able to repeat. Rod Ross and Kim Terrell-Kearney demonstrate a motion analysis program that helps players bowling technique. It allows them to see the discrepancy from shot to shot and how it affects how they play the game. Looking at a player’s biometrics and comparing different factors such as backswing, pushaway and release will help to determine where the inconsistencies exist. If you can’t start consistently, it is going to be very hard to finish consistently.
