I'm wondering where the concept of "I'm bigger than him, I must THEREFORE punch harder" comes from. I find that technique generates more power than just muscle alone. My company held a mini carnival, and one of the items was the "Test your punching power" machines. I'm a fairly small guy, 5'9" about 150lbs. I waited in line and, when it was my turn, I got a full score. The guys behind me thought, "If this skinny kid can get a full score, so can I!" and then started to punch. None of them even came close, and they were getting really pissed off. Never mind they have no concept of form, planting the foot, or generation of power from the legs and hips, after about 4 tries each, they walk away red-faced and gave me some "you must of cheated" comment. I'm sick and tired of this crap. I have no idea why people think just because they are bigger, that they then naturally have the ability to punch hard.
