An arm lift or brachioplasty is a surgical procedure that removes loose and hanging excess skin from the upper arm. The procedure can tighten and contour the upper arm.
Massive weight loss, excessive sun exposure, genetics and the natural aging process can all contribute to the loss of skin elasticity. This can manifest itself as upper arm skin laxity. Exercise will not correct the appearance of sagging skin but this does not mean you should stop your work-out routine.
