Who has/had the best cardio of all time in boxing history?

Marciano did have a very good gas tank.

 

Rocky Marciano. His whole career was built on his work rate, hard punching, and bulldog determination to win.

 

Must be you started watching boxing in the past ten years. Roberto Duran in the lower weights makes these two look like Tommy Morrison stamina wise.

 

I don't see what Muhammad Ali's stamina lacks during his "first career".
It is more than enough for the heavy category.
That footwork...

 

that ****ing kick boxer kid
ahh i forget
short blonde hair trained in the woods
seconds off winning the British title at short iirc

 

Hagler, Usyk, Duran, Spence

 

Some great calls, could add Greb to the list, from what I've read.

 

whitaker

 

You're pick is the most obvious. You could've easily regurgitated what you heard since you started learning boxing last year.

 

Yeah moron, I never seen him live. Learn ****ing English you idiot. Take it you are an alt of miniq. Very sad.

 

Ray Mancini

 

How has nobody mentioned Smokin’ Joe Frazier? He was nicknamed Smokin’ because he had the work rate of a freight train.

 

I thought it was cause he smoked a pack a day?

 

Nah, you’re thinking about Smokin’ Bert Cooper.

 

People who say Calslappy should also say Paulie Malignaggi. They can both box all night because they put nothing into their shots. Not the same as other fighters in this thread.
