Need Help With Physical Side Of Bowling

[Spud the sud]

Hey all totalbowling members I am just posted this hopefully in a correct spot asking for help on an assignment for school.

In PE we are currently studying the muscles used in our chosen sport. I obviously have chosen bowling and know yes the arms are involved heavily and that upper body area but does anyone have any other suggestion of what muscles and what kind of excercise may strengthen these muscles?

Thank you if you can help

Cheers, Ben
