Link between size and breathing difficulty???

[x11]

Does breathing become more difficult for big mass guys and why? Can't be cardio that high intensity weight training must promote good cardio to get oxygen to muscles etc.

Dam got spooked watching a vid of a massive young pro BB working for the same guys that sponsored Dallas M.

Guy was struggling for air to finish a sentence, that would turn anyone off BB. Have sort of heard other anecdotes about breathing difficulties and mass monsters.

Wut the science?

The heart is having to work harder to pump blood to all that mass. More work more energy. Same reason obese people have a hard time breathing.

Definitely tougher for me at 240 vs 200 and I'm no where NEAR those guys
