Power comes from speed (velocity) & technique (efficiency). You expect bodybuilders to automatically throw hard punches.... But more often than not they are as stiff as a board from never training; - Plyometrics - Rotational development - Speed & Power drills - Tendon Work

I've found that a lot of bodybuilders are as unathletic as fat people except the ability to lift a good amount of weight because they disrespect and disregard every other athletic department in training.

People expect bodybuilders to punch hard?

Jesus this looks painful to watch! My mans hips can’t move for shit.

Needs work

Guys like this hit hard, but they could hit a lot harder with proper technique. I trained with a body builder who could leg press 800 lbs and he had the hardest kicks in the gym after just a few months of training. Unfortunately he also gassed out pretty quick.
