I've recently lost 135lbs. in the past year, from 400 down to 265. I'm ashamed to admit it, but I've just been doing some hardcore dieting and very little exercise. I'm still losing, but I'm worried about having excess skin hanging if I lose much more. I'm lifting weights, but what do I need to do to tighten those loose skin areas such as the belly, the chest, the lovehandles and the arms? I'll post a current pic so you guys can see where I'm at.
