Some good posts here.

also factor in the more muscle put on, even if they are fast twitch - will kill your reflex time as more fibers are being engaged and in turn make your punches telegraphed. As fatigue sets in it gets even worse. I think this is the sole reason Mayweather dominated Canelo and avoided every blow (he saw them coming so easily).

when you are at your natural weight, everything works better.

you will hit your hardest when your body has matured and your weight is as low as possible (with proper training, not starving). You will be both strong and fast, and able to get the most leverage out of your body when you are limber.

Also when a fighter moves up in weight, he has to adjust his timing and style to a bigger slower fighter. He may be able to land easier at the higher weights, and will be able to sit down on punches better - where as a smaller quicker opponent can only be hit by shorter quicker punches. Bigger fighters however in general can take a better shot for the most part, and will be able to push a smaller fighter around - knocking them off balance. And the end of the day the quality of the fighter overall is the most important factor, not a few lbs or height.

this is why you see Joe Louis obliterate a 6 ft 7 250 lb buddy Baer while only weighing 200 lbs. you give a guy like Joe room to land by nature of having such a huge body, he can actually hit you harder than he could say, a guy like Billy Conn.

the Jimmy Ellis situation, Ellis naturally gained weight. This thread is about bulking up and moving up a weight class. Jimmy Ellis never looked blown up in his entire career.

if we look at Holyfield at 205 and compare him at 220. Holyfield at 205 is a much better fighter and puncher at 205. Faster, better technique and more snap. A harder puncher. You look at Ken Norton, at 205 heâs hitting much better than at 235, where he looks like a sluggish body builder lobbing his arms. Failing to stop anyone, even smaller fighters. These are 2 prime examples of fighters who bulked and lost a lot.

Queenie is "complicated" alas it is true. Some would call it the Galileo effect: If you Slugfester, or I, had been church clergy and encountered Galileo, there is a high probability we would have thought him a lunatic. Even when he got it right (predicting the moons appearance for Jupiter) he got it wrong a whole lot... Who could have known how complex Gravity was? Yet now we know that Galileo was a genius. I put him up in the top 5 genus list: Next to Newton... compared to Darwin and Einstein were practically in the toilet lol.

In truth Queenie comes up with some great stuff, I mean that no irony intended. I consider him one of my favorite posters. Within that 5% are some real gems!
