Why do I fart when I do abs exercises?

Hello Andy,

Well first of all I have just had a chuckle to myself, so thank you for this light hearted and jestful question! :-)

But on a serious note, this will simply be a case of increased abdominal pressure forcing your flatus out. My advice is as follows:

Make sure you have opened you bowels before you train.

Make sure your diet is high in fibre from vegetables, and low in gluten containing products.

I have a funny story to tell. I used to train a lady who when doing her abdominal training, and Yoga in fact, would almost always pass flatus once or twice. I used to ignore it, as did she hoping I hadn't heard. As soon as she left my studio, I used to spend about 5 minutes laughing! I know, very childish, but it did make me laugh!
