Some of us have beer bellys, and . . .
don't drink beer, sometimes it's genes, or just lack of "core" muscle strength. And, sometimes it's just a fact of life if you are at or past mid-thirties and your motabilism just "ain't what it used to be"
The thing that I have found to work the best is to strengthen the "core" muscles and working on the supporting muscle groups. I think that if you don't have spine damage or disc problems, ab workouts help the most, and your posture will be better.
So, that's a good thing right.
