exercise or surgery to loose excess?

My legs, hips are all mushy. I have lost 105lbs since my wls 8/2006. I have been maintaining my weight and maybe would like to loose 5 -10 more. My spouse thinks I can firm up and not need surgery. I think I could some but not enough to get the excess mushyness gone. I have exercised since 9/06 present. Not really hard excercise. I was thinking of having a personal trainer before I consider any surgery to firm up. Anyone out there tried the excercise route and did it help much?

Exercise will build muscle, which will give you definition under the loose skin and residual fat. It will not tighten skin. However, the skin will tighten some over the next year or so if you maintain your weight. You may want to see how much better it gets on its own. It may be enough, or you may still need surgery. A personal trainer is a great idea, though. It'll help you build muscle for that definition.
