Important Pitching Muscles

What muscles are the most important in pitching (in order of importance)?

I would say quads and hamstrings, calves, abs, lower back, upperback, forearms, pecs, tricep, then bicep. As you can see your core is the most important part. So work that more often then the other stuff.

I’d say legs in general, back and core. But they all work together, so its all important.
