My boobs are OK at the mo but my stomach is quite loose, but to be honest that doesn't bother me cos I don't care about wearing a bikini anymore! I would rather have a little saggy skin on my stomach than the great big fat gut I had there before.
Some people do go down the surgery route after big losses but to be honest cos of the money it's not really an option for me and also I am so happy with my body now compared to what it was anyway! My arms are a lot more toned now though and I'm losing fat from my thighs too. Toning exercises will really help, they have helped me a lot!
