I had a bbl 7 weeks ago. Very happy with results and now I am thinking long term Can I do butt exercises now to increase the size of the muscle to prevent future sagging or will the butt exercises cause shrinkage to the fat cells that have been newly injected into the gut muscles. I noticed I had a little more reabsorption in on cheekthan the other. Can butt exercise help build volume to compensate for the reabsorption disparity?
