The skin sag is real.

Question: I have lost 60 lbs. I work out 3 days a week with weights but the skin sag is bad in my arms. I know if I put weight back on it would go away but is my only options 1. gain weight 2. deal with it ! thin and healthy or fat and not saggie or surgery which is not an option for me. Just curious, I love how I feel and look just would love to know if anyone has any ideas or has experienced this.
