Well it smore to do with the shoulder and the leverage of the arm swinging round. I would say that 'Power comes from the legs' but thats where the technique comes from the twist of the foot, turn of hip etc... it is more to do witht the technique of the puncher than the strength
Punching is like a chain - legs/hips/abbs/lower back/upper back/shoulders and you're only as strong/powerful as the weakest link of that chain. Try tearing a muscle in any of those areas and see how hard you hit. (I missed off fist/forearm they're important too on the weight of the punch)
i used to pull the elbow in my right arm before i shortened the punch.good point with the chain bit.:good
wrong. the effect of the legs on the uppercut is neglible. the upper body is the main thing about this punch.
Well i agree :good I was just stating that upper body strength plays a good part of it,but i totally agree with how you put that. Bottom line its a little bit of everything. But more technique
Power comes partially from the legs, Frazier,Marciano,Lamotta,Tyson,Quawi, were strong stocky fighters and gained a lot of leveredge from there legs. Julian Jackson was more of a slim fighter and locked his arms and shoulders but also used his legs well. Joe Louis used his Legs and percise short punches and balanced combinations to perfection, his body was in unison.
:-( The upper body has next to nothing to do with an uppercut besides the snap of your shoulder. Your arm is held at a 90 degree angle and kept locked in that position, you drop your elbow down, bend your knees and come up with the punch and snap it at the top. Bending your legs and coming up with the punch gives you far more leverage behind it.
not true, legs come into play regardless of height, youre not springing upwards when you punch. you rotate your back foot to generate power from you legs and torso
