there are a million articles detailing the fact of low intensity cardio burning a higher percentage of fat for energy, and of high intensity training burning fat, glycogen and muscle tissue when on a calorie restricted diet.
HIIT will burn more calories, and reduce weight faster, but at the expense of a little more muscle.
SOME sprinters are very large, i agree… but you are saying that they are large and low fat but they train HIIT right? Right! Imagine how much muscle they would have if their primary concern was muscle and not speed? They are not concerned if their training results in muscle loss… hell if that increases their speed, they would celebrate it.
You cannot compare…
Google high/low intensity aerobic exercise and fat loss (or something along those lines) if you are so uncertain sherlock.
ALSO - It isnt about “eating like a man, lifting like a man.”
Jesus, is that why you train (i will refrain from say bodybuild at this point i think) to make you feel more like a man?
Is counting calories and watching fat intake manly? Is measuring your waist and arms masculine? conventional society would say no.
Remember where you are sparky, this IS a bodybuilding forum.
