What muscles do you work when you play bowling?

Answer 1

It varys from person to person depending on your form and level of training. Most ametures use their arms, legs, back and core muscles.
An elite athlete minimizes the muscle use in their arm and focuses on the muscles in their wrist to generate rotation, and rely on gravity to gain momentum. An elite bowler uses all the stabilizing muscles related to balance, mostly their core, back, and almost all of your leg muscles.
