I am 25 year old male and For the last 2 years I have gone on a new health and fitness lifestyle I was not really over weight but would be considered as fat. Now I'm am much fitter and have little fat on my body and I have gained a lot of muscle mass but I now have creases under my butt cheek and I can pinch the skin and it's about an inch of extra skin. I do all the normal exercises such as squats and lunges. I would prefer not to go the surgical road but will if I have to suck as fat injection
