top 5 best conditioned boxers today

[Southpawology]

Alvarado. Angulos conditioning looked top notch vs lara

[Dr Rumack]

Mares, Bradley, Wlad, Sergio (before the knee problem at least), Peterson, Matthysse all worthy of mention.

Floyd is obviously extremely well conditioned too, but he's such a model of energy efficiency it's hard to know how he compares with these guys who work like savages for 12 rounds.

[Sugar Adam Ali]

no order but gotta say

floyd, rigo, jmm, santa cruz, and for being damn near 50 you gotta have hopkins

also manny, bradley, froch, all go hard for 12 rounds

[thuggery]

Santa Cruz, Mares, JMM, Wlad, Froch, GGG

[Russian Crushin]

David Haye has one of the best physiques in the sport:

Good physique doesnt always mean best conditioned. Haye has a very low output at HW

[Rahat]

floyd mayweather,manny pacquiao,bradley,and wladmir.

i was going to say amir khan but he fades in the last half of the fight.

[Russian Crushin]

Devon is pretty well conditioned

Leo Santa Cruz has ridiculous conditioning

[Sam Donald]

never heard of santa cruz hahah

[alb829]

How has Bernard Hopkins name not been mentioned? He's dam near 50 and can go 12 rounds with 20 year olds... although I will say that both he and Floyd Mayweather are 2 of the most relaxed fighters with low volume punch outputs....

[PACnPBFsuck]

Donaire, Rigo, Pacquiao, Devon, Bradley
