The biggest risk factor for loose skin is fast weight loss; those people on the Biggest Loser? You'll notice they don't wear skin-tight stuff.
There's not a whole lot you can do, other than aim for slow, healthy weight loss (1-2 lbs per week, 1 or less when you're closer to your goal), stay hydrated, and strength train.
It's also about genetics and age. Working out is generally not a risk factor.
