What are the most important muscles for boxing?

My educated guess...

• big forearms for gripping boxing gloves easily

• legs for improved mobility and power transfer

• chest for straight punches being strong in the clinches

• biceps/shoulders/back/latts for looping punches like Marcos Maidana's overhand right and uppercuts

• abdominals for head movement

I know that cardio is a necessity, hence why boxers don't overdevelop their muscles. They use a lot of cardio. The first time I hit a heavy bag I was surprised at how much cardio it took. I was gassed out quickly!

Hips are the single most important athletic part of the body for essentially every sport. Any real athlete knows this.

Given that the peck deck/seated fly is an important exercise for pectoral muscle, I'd say they're just as important for hooks as they are for straight punches.
