Keep Zombie Lesions from Eating Your Brain

We know cardio exercise is good for the brain. A new experiment suggests strength training might be, too.
 
By late middle age, most of us start developing lesions in the brain’s white matter, which connects and passes messages between brain regions. These lesions affect cognition.
 
The experiment tested healthy women, aged 65-75. One group did light strength training once a week, another twice weekly, and the control group did stretch and balance work twice a week.
 
After a year, lesions had progressed in the control group and those who lifted once a week. But those who had lifted twice a week had significantly less white matter shrinkage.
 
Here's yet another great reason to do strength training:  prevent zombie lesions eating at your brain’s white matter.
