Any of you done this before?? I just did, today in fact. being the idiot that I was I decided to workout on an empty stomach, all was good until I was 3/4 of the way done, then my stomach started burning. It felt hollow, I knew my muscles werent sore, but I couldnt go any further. It was a bad feeling.
Don't be an idiot, eat an hour or so before a workout XD
