Comes from the legs, is transfered by the torso, and unleashed through whichever arm you are throwing it with. Usually fighters who are able to get extremely good instantaneous leverage have good punching power
How do guys like Haye, Hagler and Pavlik generate such power when it appears they have legs lacking in strength? Is it just their lanky builds that hide how strong their legs are?
A lot of it is technique. They say punchers are born but a lot of that is to do with how people naturally get their bodies into their punches. There are other things though. I spar with some guys and you think they are gonna be huge punchers..but then they aren't. Other guys can hurt you with their jab so I'd have to say a certain part is born and a certain part is technique. As for technique..it all comes from balance. You need balance to deliver the maximum momentum you can as you generate it from yor legs and through your body and to your shoulders.
I think it's all about technique and timing but of course it helps if you can put some weight behind it!
accuracy and timing or so i was told when i was a kid, the explaination always made sence to me and it stuck, it was explained something like this accuracy - a punch has its maximum power for only a small window, hit the target to soon in the action and the punch hasnt developed its maximum power, to late and your body is pulling the punch back. timing - something along the lines of firing the muscle groups in the correct order and at the right time producing a fluid development of power, cant be taught ie. 'a natural puncher'
Starts at the balls of the feet, up through the legs. As BSLICE said a lot of it comes from leverage (ala Mike Tyson the short ****er). Also remaining relaxed throughout the punch is extremely important. Beeing all tensed up and musclebound is a hinderence. Speed comes into factor as speed + strength = POWER. Finally brute aggression seems to work quite well (Ray Robinson, Max Bear, Tyson, Pavlik, Katsidis, Marciano, Lamotta etc.)
Well, it doesnt all come from the legs, but remember, those are big guys u mentioned, but still, just make sure u are looking at their thighs rather than calps. But it's really a lot about how u know ur body, and the technic u use, take for example Kermit Cintron, very solid power, yet not that strong legs, but his power comes from the levarege he gets with his height, reach, wide back, and strong shoulders. Thats why i think he should move up to 154lbs, i think he could really use some leg power, and be more energized in there, but thats just what i see, not many people seem to agree with me on this.
It goes through the legs, the torso plays it's part as do numerous other unseen supporting muscles and through the shoulders then the explosive whip in the arm, it's a real compound movement. correct stance is pivotal.But the single most important thing is muscle fibers, a persons genetics. You will not hugely improve someones power if they are not explosive. Remember size means nothing, you are born with the same ammount of fibres that you die with. Training just enlarges them like a balloon.
