My lower belly (the navel area and below it) sticks out a bit. I am not fat. I am really slim; in fact my chest is just thin and normal, but the lower belly sticks out a bit.
Please suggest to me some solution for this.
Update : Thanks all of you for your answers. I examined myself, and it seems my problem is neither loose connective tissues, nor anterior pelvic tilt. As far as being slim is concerned it is kind of that I am not really really slim, but just a normal kind of guy, not skinny and not fat at all. I am a programmer, so I sit at my computer all day programming, less physical activities, so I also think that I might have a fat belly due to lots of food and no exercise.
Please suggest me a good exercise for a fat belly, specially the area around the navel.
