From Quora re: Marciano's power "He had a special made heavy bag. An average heavy bag is 60–100 pounds. Marciano’s was 300 pounds! His theory was if he could punch hard enough to move a 300 pound bag, he could hit hard enough to hurt any fighter." “I had a website on Marciano from the late 1990’s till Geocities closed. Then someone put all the old Geocities sites on line again and my site is back up, though I can’t edit it any longer. http://www.oocities.org/colosseu... During the time I maintained it, several years, I was e-mailed and had discussions with Peter Marciano, Rocky Marciano Jr., Archie Moore’s daughter J’ Marie, Charlie Goldman’s nephew Andy, and Ben Bentley’s daughter Iris, as well as a phone interview I did with Mr. Bentley. (He was Rocky’s PR man and also a well known boxing personality of the 1950’s) I still discuss Rocky and Charlie with Andy Goldman now and then. Rocky’s training was harsh by any athletic standards. He was probably the best conditioned fighter to ever live. Ben Bentley said Rocky ran 5 miles a day, every day including Christmas morning, and upwards of 15 miles a day when preparing for a fight. He trained so hard that his trainer, Charlie Goldman, would have to make him stop. His conditioning was so good that he literally couldn’t get tired in a fight, which meant his punches were always hard. Archie Moore said he kept waiting for Marciano to punch himself out, but he never did. Rocky’s brother asked him what it was like to be in such shape, and Rocky said, “It’s a wonderful feeling to know that you’re never going to get tired in a fight.” He had a special made heavy bag. An average heavy bag is 60–100 pounds. Marciano’s was 300 pounds! His theory was if he could punch hard enough to move a 300 pound bag, he could hit hard enough to hurt any fighter. He sometimes went to the YMCA and would stand in the pool at shoulder depth and throw punches till he was exhausted. Jersey Joe Walcott said, “Marciano threw every punch like you throw a baseball, as hard as he could.” Also, his short arms were a major asset where power was concerned. The further a hurled object travels, be it a baseball or a fist, the more energy it loses. A pitcher throws from a mound 60′6″ from home plate. But if he moved up to 50′, his velocity would increase significantly. Rocky had short arms, so his punches traveled a shorter distance to impact. This is from my site. Marciano’s incredible power began in his feet as they pushed off the mat. The energy was fed by his thick, muscular legs, the swivel of his hips, and the twist he’d put into his upper body as he snapped forward his arm and fist. Where the power came from might be best illustrated in a letter I received from a doctor who works with internal medical problems and trauma. He told me this: "Now what determines the power of a punch? I mean the formula… The effect of a punch is calculated by the energy applied at the site of the hit. So the kinetic energy of Marciano's punch, that is the degree of damage the punch would generate, is equal to 1/2 mass x velocity x velocity (1/2mv2). Rocky's was equal to the mass of the arm plus the weight he shoved forward with body weight. Next, he hit in close. As your arm moves forward the time from beginning to end increases as you increase the distance of the thrown punch. Since velocity = feet per sec, that means the longer the range the less velocity. Now the energy generated is, remember, mass times vel x vel. Well if your punches are so much shorter, traveling only a few inches, your velocity is incredible! And the transmitted energy at impact is enormous! That calculation of energy is the destructive force (damage) to the body. Basically he broke his opponents up inside. Had George Foreman been a swarmer, he would have been a better fighter. He was a slugger. But as strong as he was he hit from too far away. Frazier was not as powerful as Marciano. He had a similar style, but didn't hit as hard (didn't use shifting weight, etc)." By nature, Rocky’s body was perfect for generating the power he did and his almost fanatical training allowed him to deliver that power from round 1 to round 15. Dan Culp, Owner of boxrank.org and aspiring pro judge: He had innate power that is not something that can really be taught or trained for to any great extent, but he had a tendency to apply that power late in fights, despite throwing a ridiculous number of punches for his weight class. He was like a heavyweight Leo Santa Cruz, but with an eraser that Santa Cruz lacks. One thing that his trainer, Charley Goldman, noticeably improved in his fighter was Marciano’s balance and footwork, which would naturally help him deliver his power more efficiently than when he was a more crude version of himself early in his career. Aside from the sheer dedication he showed in getting himself in such fantastic shape so consistently, Goldman's remedy for this problem was probably the most notable aspect of Rocky’s training that was different from the average boxer of his time. Seeing that his fighter’s footwork was so all over the place and that it hampered his effectiveness to some extent, Goldman was known to tie a string around Rocky’s ankles during heavy bag sessions. The fighter would be given enough slack to move his feet as he should, but no more. The idea being that if he got too undisciplined with his footwork, the string would cause him to trip and fall. Obviously that would be pretty good incentive to keep your feet under control. This benefit naturally isn't only relevant to power, but it does mean that his feet were more often in position to throw balanced shots that maximized his natural force. It also increase the efficiency of his combination punching, which cannot be overlooked as a key factor in his knockout record. He overwhelmed his opponents with his stamina and volume as often as he did with his raw power. The usual, heavy bag, cardio, and abs. He was just naturally gifted with power and the relentless punching ability that got him to defeat Archie Moore, Jersey Joe, and Ezzard Charles by Knockout. His best punch was a right hand called the Suzie Q."
I don't know about the 15 miles...don't know if I believe it...but he may well have taken the rest of the day off
"When the esteemed Charley Goldman, who would become Marciano's trainer, first saw Rocky, he told Angelo Dundee, his assistant, "I gotta a guy who's short, stoop-shouldered, balding, got two left feet and, God, how he can punch." With his instinct for the attack and the power of his right hand, Marciano knocked out his first 16 opponents, nine in the first round. By now he was under the tutelage of Goldman, who trained fighters for New York manager and promoter Al Weill. Goldman instructed Marciano to fight out of a crouch. "Charley taught the technique that if you are short, you make yourself smaller," Dundee said. "Charley let him bend his knees to a deep knee squat. He was able to punch from that position, come straight up from the bag and hit a heck of a shot ... It was just bang-bang-bang-bang-BANG and get him outta there." more here: https://www.espn.com/sportscentury/features/00016159.html
Yes, Marciano was probably the hardest trainer ever, with almost unlimited endurance. And yes, the further a hurled object travels, the more kinetic energy it looses - so, the same pitcher will obviously throw a faster (at the time it reaches the catcher) ball from 50' away, than from 60'6". We don't have to look into the physics to determine this - common sense tells us, that this is the way it is. But does this mean, that a shorter punch carries more kinetic energy at the moment of impact, than a longer punch... thus giving Marciano an edge in punching power, because of his short arms? No, of course not! As your arm moves forward the time from beginning to end increases as you increase the distance of the thrown punch. Since velocity = feet per sec, that means the longer the range the less velocity. Now the energy generated is, remember, mass times vel x vel. Well if your punches are so much shorter, traveling only a few inches, your velocity is incredible! And the transmitted energy at impact is enormous! Surely I can't be the only one, who finds the above a bit (to put it mildly) strange?
That is the reason I posted the "info" up.....knowing my compadres would see the errors in Mr. Quora's thinking.
There are quite a few things here that are stated as facts that I would view as "problematical." As regards power many of the greatest punchers ever have been long lanky guys with huge wingspan and spindly legs. Dempsey was top heavy ,Bob Foster? Sandy Saddler? The hardest one punch guy around today is probably Deontay Wilder,he has chicken legs Muhammad Ali had a 300lbs bag which is considered to be responsible for his bad hands later in his career. Balance ? Marciano was on the floor several times from missing punches,that is not indicative of good balance.
Nice to see all the old Bunyanesque Marciano fables are getting a walk in the fresh air.... lest they get musty and stale. Oh, but Peter Marciano said so? Great objective source.
Interesting point, he certainly did have those moments when he looked like he was back in their 4 rounders. On the other hand Marciano had about 50 fights and was only really knocked down twice. You would think that a guy who is always punching, leaving himself open would see the canvas alot more if his balance wasnt solid. That is a bit of a mystery.
Marciano did a lot of cardio not sure if it was 15 miles a day but he blew up between fights and sitting next to Floyd Patterson he was double the with in shoulders neck and arms. Joe Louis was heavy when he KO'd Nino in an exhibit, I heard he was near 230lbs but got back down under 210 for a defense. The thinking was be ready for 15 rounds back then, Marciano also punched in water and threw rocks and hit a 300lb heavybag. Not sure if this all helped but it certainly helped his mind because he never felt anyone could beat him.
Always great to go back and read some of the Sport & Sports Illust. mags of the 1950's. Boxing champs were treated differently by the media back then.
Marciano overswung from odd angles but his balance was good when he shifted his weight into a power shot. He sits down on the right hand that blasted Walcott and if you watch Charles2 the final KO, he misses the left but quickly loads up the right with all his weight and that one dropped Charles very hard. there is the balance of a ballarina (which Marciano was far from) but look at his punching balance and how he used his legs and shifted his weight & power, his punching balance was fine.
