Re: I thought punching power could not be improved at all!
Dealt with, if you're this big ****in puncher, why not post a video of you hitting a bag?
Weights may increase punching power to an extent, but there are certain individuals who are genetically inclined to hit hard.
Marquez happens to be one of those guys. His punching power is one of the reasons why he's such an effective counterpuncher.
As I've previously said, I've seen guys who were ardent weightlifters who had very good numbers, but for some reason were incredibly weak punchers, yet had many of the attributes that guys who lift weights too much do.
They were very hittable.
On the same token, I've seen guys that never lifted a weight in their life, but had monsterous punching power for their weight.
I don't know how much it contributes. It's hard to say. I've always been a hard puncher, but I've also lifted over 1000 lbs with my combined 3 lifts.
I don't lift weights now though, but I can still punch.
