So, in January I was 170lbs (12st2) and today I am 127lbs (9st1). Yay! 
However I have had one child, and my stomach does have stretch marks and is soft. I'd also like to tone up around my under arms and upper arms.
I think I kind of thought if I got down to a good weight, I'd magically look like a bikini model! Alas, no....time to hit the gym, as although I'm pretty slim-ish now, I'd still not be that comfortable in a bikini.
Any advice, success stories, general discussion much appreciated......I'm 5ft 2 if that makes any difference....
