Long Duration Cardio & High Calories

Has anyone here ever tried a high calorie diet with lots of cardio?

One of my friends eats 3300 calories and does 1.5 hours of cardio 4 days a week, while lifting the other 3. He gets ripped (under 4% bodyfat).

I’ve tried this and it never works 400 grams protein, 250 carbs, 70 grams fat.
Has anyone else ever tried anything like this?

I’d rather do tons of cardio if I could eat, but I always end up eating 1750 calories or less with under 100 grams of carbs or less. It really sucks!

if i recall correctly, under 4% bodyfat and you are on the brink of death…
