Want to see my real belly fitness routine? These are the crunches that I do to keep my tiny belly so tight and firm. Watch me go through my routine of 40 crunches and hear me count out each one in each position. See the movements that my belly goes through as each position targets a different muscle group, and you can almost see my stomach muscles growing under the strain. *BELLY FETISH, BELLY BUTTON FETISH, PIERCED BELLY BUTTON, CRUNCHES, EXERCISE, SPORTS BRA, FITNESS, BELLY FITNESS, SKINNY GIRL, WORKOUT*
