I think for MOST people, when they gain weight (which we spend 90% of our time trying to do), they gain it in their bellies first and then other body parts... I've heard this from friends, family, and different articles. My hubby also does some personal training and said that that is normal for everyone.... especially as we age.
I do think we have skinnier arms and legs than most though, which I too find strange. I mean, eventually, one would think it would HAVE to start going to other body parts, eh?!?! I mean, I've put on 20 lbs in the last 2 years, and NONE of it seems to have gone to my arms... I can still fit my fingers around my arm!
Anyway, weight training REALLY helps A LOT! I have been lifting, and find my legs have really filled out... and, I've only done it a few weeks and only do light weights. I just do lots of reps. I also do cardio on the elliptical, which is a great leg workout. Now, arms are a complete different story... I've tried to start working them, but it is slow going.
I also think the tummy appearance has alot to do with the barrel chest. I am EXTREMELY self-conscious of that... even though my hubby says he doens't know what i'm talking about... I think he's just saying that to be nice. Anyway, I think if I can find a way to even out and "fill out" my boobs, arms, AND legs, my tummy won't stick out so much, and neither will the barrel chest. I've also started to do sit-ups everyday, but I've had little luck with that in the past, so we'll see.
Anyway, just know that its normal for the "middle section" to be more plump than the rest of your body (CF or not). And, like most things, we just seem to have to work harder to live more like others. Urgh!
