I m 22.I got loose skin in my triceps like bat wings due to weight loss. Will working out the tricep muscles with weights in gym tone the loose skin??

Bat wings in. the arms from weight loss can tone up to a degree by working out, perhaps w/a personal traineer. Beyond that you MAY need surgery. Please work out and consider meeting w/your doc to discuss plastic surgery or work at living peacefully w/the situation. Peace and good health.
