I've noticed as I get older my posture starts to get worse. (It doesn't help when I have to sit in a chair during the day, either.) Looking from the side, it almost looks like my lower back bends in a little bit (causing my lower mid-section to naturally--or unnaturally--jut out a little). I've been doing some ab-strengthening exercises (picked 'em up here) like the bug series, and that seems to help a bit with lifting issues (rows, etc.). And I try to be conscious of my posture as well. Still, might be easier if I had specific things I could do to work on it.
Anyone have any tips, exercises, or other for posture that might help me or others with similar issues?
