Here's what I started out to say ... Before you go another 1/10th of an inch in altering your own size .. see if your size-queen chick can walk around the house with a pair of Luna Beads staying inside her.
If you hear "shploort .. blam blam" on the floor, the issue is not your size. Chicks can do exercises .. too.
