Excerise programs

Hi  I'm looking for excersie programs that are made just for people who have had wls surgery. I did find one called  Weight 2win  its for bariatric  surgery people.  before and after.  I just wanted to know if any one heard of this or any other programs like this one.  being large and have to loose a lot of weight the skin gets real flabby.  I'm just trying to  get rid most of it.  I don't want to think about another surgery  to remove the loos skin.  It's very expensive. so give me a shout if any one knows of any programs.  Thanks
