Am I doomed to being chubby the rest of my life?

So I have to admit...I have been chubby my entire life. Before you protest let me explain....as a baby, think rolls, cheeks that I still remember little old ladies coming up to me and squeezing. Must have made an impression since I remember is 25 years later. As I grew I may have gotten taller, but muscles have never pierced through my ever so thick layers. In H.S. there was a girl in my church and school that had guns(arms). Natural beautiful muscle tone. Her name was Michele Weaver. I don't think she even lifted, there was something on her genome GNCA that stood for "BUFF" I admit, that by my Sr. year of HS I was still chubby. My chubby peaked at 20, interestingly enough the peak of my "finding my eternal partner, really need a high self esteem-time of life" No luck with that-dang it. Couldn't put down the Twinkie. Got married-starved myself for 3 days straight before the wedding. Count them 1-2-3. Not even a carrot till the day of the wedding. My disclaimer- don't' try this at home girls. My honeymoon, I ate and ate and ate, plus flying makes me bloated...thus I had a F.U.P.A. (Fat upper pee-pee area) You know what I'm talking about girls. Oh, speaking of girls. That's the ONLY good thing about being chubby. The "girls like it" I liked it. Yes, I once had a nice large rack...but I was chubby. Then the most interesting thing happened. Pregnancy. Gained a fair amount of weight 35-40 poundaroos and then out comes this 7 pound baby. You read in magazines that the baby plus water and placenta equals about 15-20 pounds...they LIE!!! Post delivery I get on the scale and I had lost 10 pounds tops! But don't start to feel too sorry for me. I started nursing and nursing some more. Ryan was 20 pounds at 9 months old. So you can imagine what I looked like. I was now skinny FAT. You know the term. You are a shrunken version of your once flabby self only smaller. It may look like this.....

No real muscle tone, still have the skin and puffiness. I do appreciate that I can cover this up in cloths mostly and I like the skinny fat vs. the chubby fat version of myself. So this leads me to my quest..or question...could I ever be BUFF? Like athletic and muscly. Could muscles exists under my layer or layers of facist tissue and fat?

Could I look like this
No! I'm offended, ok maybe not too much, this is a picture of the reigning Ms. Fitness. So I'm not going to go crazy, but I have started this new class that makes me feel like rubber when I'm done. (That's good right?) And I am going to try to let my muscles shine, well at least SHOW. Am I going to show you a pre & post picture of myself in a bikini holding a newspaper...ummmm what ARE YOU CRAZY??? Just now that if I never talk about it again. I look more like the girl in the above picture and less of Ms. Fitness. Alas, I am grateful to have a healthy body that functions fueled mostly by flour tortillas and ghiradelli brownies, SORRY!!!
