Exercise does not tighten skin

While I do recommend regular exercise for general health, it is important to have the right expectations. It does not tighten skin. The degree to which skin shrinks with weight loss is determined by its natural elastic tone, which isn't as good for someone in their 50's as someone in ther 20's for example.

There are some non-surgical technologies which can tighten skin such as Thermage but the effects are not usually dramatic especially after weight loss; again, a matter of appropriate expectations. So do continue with your exercise regimen but don't expect to see the skin tighten as a result.
