Obviously at not even 200lb, I'm no where near fat enough to not be able to lie on my belly. But on the weekends when I've been a busy little piggy, calorie consuming, I can't even sit up by Sunday night, I have to lie on my back, propped up massaging my big ol' gut in bed. On these days, front sleeping is out of the question! I've even taken to putting a cushion under my belly to support me in bed, just like a pregnant woman. But I have noticed that my belly fat is now big enough to splurge side ways when I lie on my side, (just like the group logo) even when empty!!
