We all know that exercising keeps our muscles from shrinking, but scientists at the University of British Columbia examined how weight training impacts our brains.
A preliminary experiment specifically examining the relationship between resistance training and brain health discovered that regular weigh lifting sessions could slow age-related shrinking of white matter, a material that connects different regions of the brain and allows them to communicate.
In the study, 54 women between 65 and 75 years old strength trained either once or twice a week. The rest followed a routine of stretching and balance exercises twice a week. After a year, scan results showed less damage to white matter in the brains of those who hit the iron two times a week compared to those who lifted once a week, or not at all.
