Power punching...just like Marciano

I was just watching Rocky Marciano KO Jersey Joe Walcott with a perfect right cross on youTube...to see it:(http://www.youtube.com/sto9joe):on my youTube channel, click on "Playlists", click on "two and a half men" & go to page 5 (whew)! To crack like Marciano did, you need to master 3 things: range/ moving body weight/ structure of punch. (A) Range : you have to know (from endless practice) the exact distance you are from your opponent where you will hit with maximum power (taking into account the length of your arms,the depth of your stride when you shift weight). Too far away: you will reach with your punch,lose structure & bleed off power from your weight shift! Too close: your punch becomes a PUSH (now a push can be GREAT on the street: if you pin his foot with yours to anchor his base while you push his COG outside of that base: he falls down much easier! This would be a FOUL in the boxing ring,however). (B) moving your body weight: you have to get your body weight moving into the blow (Rocky stepped toward Walcott with his left foot as he brought over the right cross). You deliver the shot AS your weight moves forward; NOT step forward,then punch after your weight has already shifted! To accelerate power while punching: rotate hips counter-clockwise with a right cross (clockwise with a left hook) as you pivot on your right foot (pivot on left foot with a left hook): the action is like grinding out a cigarette on the floor! This adds even more body weight & momentum behind your KO blow. (C) Structure of the punch: you have to KNOW how to punch so the bones are aligned properly,the muscles & ligaments can drive the skeleton & absorb the impact of the punch so you hurt him without getting hurt yourself! Example: range & momentum are perfect; but your fist is only half-closed, or your wrist is bent upon impact: you don't get optimal power transfer into your opponent AND your risk of breaking your hand /wrist increases! THEORY is great; however this MUST be practiced countless times on the bag, on focus mitts, in sparring. Stepping into range is key the way I see it: your opponent is going to be in constant motion & you have to "know" (in a muscle-memory way, not merely an academic way) how to move in & punch him out: just like Marciano did to Jersey Joe! I welcome any information I might have missed; you may teach me a thing or two! Peace...Respect...Blessings to all--------joe (Practice with care!...read the disclaimer, posted on 9/11/07)
