Losing ONE POUND can never in a million years weaken an adult male.

At what point do they get weakened? It's not like Cotto walks around at 147. He already has to cut 30 lbs. or so to get to 147lbs. The reality is that Cotto is already draining himself to get to the WW limit. Requiring him to cut an extra two lbs. is not doing him any favors. Cotto is the only one who knows how much, if it all, the extra weight loss affected him. Everyone's body is different and reacts to weight loss differently.

 

so he can set the target to 144 then next fight 143 then next fight 142 so on and so on theres nothing left to shred its very very hard

 

You're looking at in the wrong way. His punch output and overall endurance looked so much better in the Foreman fight, then in the Clottey and Pacquiao fights. He didn't look right at all fighting those two, he looked weak down the stretch.

 

Roy Jones also said he's back to his old self in the Calzaghe fight.

 

Doesn't matter as you get older, your metabolism starts to slow down. He's at the age where it starts to do that and that will affect how he makes weight. Like BigReg said, he already has to cut a bunch of weight already.

 

but you see its a new procces each camp he goes up in weight between camps so he may weigh 158-160 going in so he shreds the weight but then has to find one more pound from somewere hes already dehydrated like most fighters making weight , very low body fat percentage so weres the one pound coming from

 

This person doesn't know anything about cutting weight or perhaps boxing... Of course Cotto or any fighter is going to say they feel great... What moron is going to admit heading into the fight saying they feel weak and drain trying to make weight. The sport of boxing not only deals with the physical aspect, but mentally as well. Tyson even said he beat most of his opponents with intimination. Cotto was struggling with both and Manny and his coach simply took advantage for the right moment to face him. Anyone who doesn't see this is just a being naive.
