Belly fat can creep up on us as we get older....but it's not inevitable. A bulge is avoidable. Most of the fat around our bellies isn't gained--it's weight that's shifted due to weakening bones, hormone changes, or possibly childbirth. We can slow the shift with strength training. A study from the National Institutes of Health showed that overweight and obese women who lifted weights just twice a week saw a smaller increase in intra-abdominal fat (7 percent over two years) than those who didn't exercise (their intra-abdominal fat went up 21 percent in two years). So the take home lesson here is: start lifting weights and we'll keep that belly fat at bay...and we might even get Michelle Obama arms as a perk!
