I started doing crunches last night because my belly is very flabby. I got through two sets of 25 but my belly started to hurt a little. Almost like I had a tummy ache. I just wondered if that was normal.
Next question: I did them on my bed. Does it matter where you do crunches?
Final question. I read somewhere that you have to breathe a certain way when doing crunches so that the muscles don't bulge out. Is this true?
