Ok. This is my question. Yea, I've been reading BFL - Just for some inspiration here. People say 30 minutes cardio is barely enough to burn a considerable amount of fat, yet I lost 70 lbs on it!
Now what do you all think about the 20 minutes, breakneck interval training? Some of you will say no cardio at all, but it's hard for SOME of us to drop a considerable amount (15 lbs.) of bodyfat without it, or a 20 week diet.
IMHO: 20 minutes bust ass > 30 minutes jerking around.
