I had pretty severe diastasis recti (abdominal separation) with my second pregnancy and knew that I wanted to try a corset to help my recovery.
I started using my Bellefit several days after delivery, and within two weeks I could go down a corset size!
I wore the corset all day long. even for a daily 3-4 mile walk.
My diastasis has significantly improved from a gap the size of about 5 fingers down to only about 1 finger wide.
