will people think in the now and stop focusing on old ass advice so stubbornly? high weights with low reps with build great power and strength. This, coupled with great punching technique will give you some rocks for punches.
Where the hell do you get the idea that wider/broader shoulders has anything to do with punching power. I can name about five power punchers off of the top of my head that prove that wrong.
Foreman had the talent (extrodinary power) and TRAINED HARD!! I believe his training had to do with perfecting his strenths (uppercuts) and imrove his weaknesses.
Spend a few years (or perhaps a few decades) down at the gym and wait for a puncher to walk in the door. With no prior training he will be able to hit the heavybag harder than anybody in the gym. What training accomplishes is learning how to deliver the firepower, not developing firepower. If you lack firepower no amount of training will give it to you.
Yeah, every few DECADES a "born" puncher comes along. For the rest of them - there's training. There IS a limit to how much of a puncher you can be...but to say that punchers are ONLY born is simply false.
the idea is, if your shoulders are used as a lever, powered by the rotation of your core, then the longer the lever(broader the shoulders) the greater the multiplication of the torque from your core, transferred to your fist
Natural strength, although Shavers (who hit harder than Foreman) said that he hit harder after chopping wood. Strength is natural, you just have to train it to its fullest.
Great punchers are born, but they are still babies in the begining that need care and proper supervision to grow up to be the best.
