Having been very fit & active my entire life, I let myself go in my late 30's. 2-1/2 years ago I started exercising and sensible eating. I lost 60 lbs. and am within 2-3 lbs. of my ideal bmi. I exercise intensely 1-1/2 hours most days. I am now 45 years old and pretty fit. My question is: I still have a small amount of loose skin in my abdominal area. Will this disappear with continued work - or am I stuck with this "scar" of my fat period?
