Who has/had the best cardio in the boxing history?

Duran had Unreal stamina. In 49 fights I've never seen Floyd tired. They stand out to me. That's because he has a conservative style.

Salvador Sanchez and SRL springs to mind. Right now, probably Lomachenko.

Aaron Pryor comes to mind but that thing with the black bottle, is suspect and his trainer was shady probably put some drugs to give him stamina in there. Prime Pacquiao I never seen a fighter throw with that much stamina, and relentless he was not dropping weak **** either, he was throwing fast straight punch power punches down the middle non stop at 122-130 pounds. He would do that for 12 rounds, moving his head, remember when Pac used to fight like Ippo with that head movement firing off the straight left down the middle. of the old school guys of course Henry Armstrong.

Mayweather never looks tired

Mayweather. Behind all the glitz he's a workhorse, never misses a day at the gym and looked in top shape in every fight he's been in.

Listen I hate the guy but credit where credit is due -- Kenny Rainford had some really stellar stamina. Sutherland woulda beat that ass but he started to gas after the first 20 seconds.

Henry Armstrong

Duran had Unreal stamina. In 49 fights I've never seen Floyd tired. They stand out to me.

Phillip Holiday

This. Can't forget about Hank Armstrong either. Perpetual motion. Also Paul Williams was a machine too as far as recent. This is true. Williams had a ton of energy for someone fighting below his natural weight. If anything you'd expect him to move more not throw loads and loads.

Aaron Pryor. This. Can't forget about Hank Armstrong either. Perpetual motion. Also Paul Williams was a machine too as far as recent.

Is Antonio Margarito a person belonging in that list? I would say no. It had less to do with his cardio and more to do with the fact that his opponent's broke down quicker due to being hit with bricks. Of course you're gonna overwhelm people when there's cement in your gloves. Once they were removed, we saw the results, all of a sudden he looked like a sloppy featherfisted bum in the Pacquiao and Cotto 2 fights. They showed he was a fraud. Michael Carbajal definitely belongs on this list, he came from behind a few times... First fight with Humberto Gonzalez and the fight with Jorge Arce (Both are amazing, especially Arce he was on his very last legs at that point).

Is Antonio Margarito a person belonging in that list?

Tito Trinidad. Dude was a straight up machine.

Aaron Pryor. Agreed. He threw a lot of punches and hardly looked winded. This, the dude was like a windmill with his punches. It's crazy when you watch the Arguello fight's how fast he was and how it continued even as we got into the later rounds (oh wait, that black bottle was there :nonono:, the one that got mixed SMH). Still, Pryor was awesome. Shame on Ray for not taking him on he was a legend. 2 of the 3 "Sugar's" deserve mentions too. Leonard and Robinson.

Calzaghe just torqued his wrists, I can masturbate for half an hour and exert the same energy. That's because your using your finger.

Aaron Pryor. Agreed. He threw a lot of punches and hardly looked winded.

Aaron Pryor.

salvador sanchez(vs Azuma Nelson), sugar ray leonard(brawl in montreal), margarito,duran -all had exceptional cardio.
