I'm not overweight but I've never weighed this much!

I've always been a petite figure and when I was about 26 I started gaining and I developed a bit of belly flab. Now I'm 29 and I weigh 140 and I'm 5'3. I used to weigh 115! I know I need to get to the gym a lot more and I really don't eat that unhealthy. I'm just being lazy lol but I'm really not insecure. I have curves that I really never had before and I like the little bit of "junk" I've developed! But I definitely could use a bit of toning! Does any one relate to what I'm talking about???
