Researchers at the have found that walkers tend to be in better shape than their gym-going counterparts. In the study of 50,000 people over the age of 13, people who walked briskly for at least 30 minutes a day were more likely to have smaller waistlines and lower BMIs than those who engaged in moderate-intensity activities at the gym. The results were particularly pronounced in women and people over 50.
While it's important to keep in mind that the study is correlational (meaning, people who reported walking tended to also be thinner—so researchers don't know if the walking was the sole reason for the outcome), the results are still great news for anyone who is gym averse (read: most of us). Plus, it's free, you can do it basically anywhere, and it's been proven to reduce the risk for heart disease and diabetes, among other health problems.
So what are you waiting for? Head outside and get your walk on!
