2 min read SCIENTISTS HAVE JUST given you one more reason not to skip your workout . Regular exercise could be turning back the age of your brain—by almost a year. It didn’t take a lot of exercise, either. When people exercised for 150 minutes a week , their brains stayed younger. (If the number sounds familiar, it’s what multiple health organizations, including the CDC recommends for physical activity.) All they did was break their workouts into two 60-minute cardio sessions in the researchers’ lab, followed by a half-hour home workout . When scientists reviewed the MRI brain scans before and after the year-long trial, they saw that the brains of the regular exercisers were 0.6 years younger than when they first started out. Researchers also looked at the brains of people who didn’t work out at all. Their brains were 0.35 years older . Put together, the difference in brain aging between both groups was nearly a year.…
