These are three main physical elements which affects the power of the punch:
1. Leg Power (power turns into speed) - 39%
2. Rotation Power (power turns into speed) - 36%
3. Arm Power (power turns into speed) - 25%
As you can see, the power of your arms aren't that important in the power of throwing a punch. That's why you can still throw a hard punch with "not-that-much" ripped arms. Plus the size of your arms doesn't rely to the strength of them. Strength comes from the amount of muscle strings and not the size of the muscle strings. That's why a bodybuilder is much weaker than a powerlifter, but has bigger arms. The arm of the bodybuilder has less muscle strings than the arm of the powerlifter, but his muscle strings contain more protein and water storage, while the muscles of the powerlifter contain more smaller muscle fibres(strings), but much more of them.
Here are some examples of the bicpes size of famous boxers(in their prime) who didn't have had big arms, but still huge punching power:
George Foreman: 14 3/4 inches (that's little for a 6ft 3 in guy)
Rocky Marciano: 14 inches
Joe Louis: 14 inches (that's little for a 6ft 2in guy)
Bob Fitzsimmons: 13 inches (at a height of 5ft 11.5 in)
Sonny Liston: 15 1/4 inches
Max Baer: 14 3/4 inches (at a height of 6ft 3 in)
Well stud, the size of someone's arms has really very little to do with how hard someone cracks.
Lotta times, power comes from technique, how the punch is thrown. You say you pivot into your shot, you are correct; you're using your whole body. That one little motion of energy is a difference-maker.
In karate, one is taught to throw a punch with the whole body, and that rotating the hips with the back foot planted on the ground that generate more power than an arm punch.
Ever notice in a hockey fight: they can't knock each other out? Why?
It's because they can't plant their back foot, because it slips on the ice.
Punching power is not always about size and its not the size of your arms
the power comes from the legs and torque through the body.
Muscle is timing & maybe the size of the fists, lots of punchers have thin arms & bigger fists. Bob Foster, Tommy Hearns, Diego Corrales
Ali Raymi is one of the hardest punchers pound for pound today knocking out all his opponents in one round and look at his arms, they look very thin. However his fists look somewhat bigger
Bruce Lee for example wasn't very big he was lean and ripped but had amazing power.
Your not on Steriods
My muscles aren't super huge but they're big. Not as big as I want them to be. My punching power is extremely hard yet I don't have huge muscles. I use my whole body when I punch, punch with a twisting motion and a foot pivot in an orthodox stance. I still don't see why my punches are as hard as they are when my muscles aren't super huge. I feel like I kind of answered my own question lol.
