Lift weights. Not only is strengthening your working memory similar to strengthening your physical muscles, but strengthening your physical muscles can actually strengthen your brain!
Teresa Liu-Ambrose has spent her career researching the connection between physical strength and mental strength, particularly in older individuals. Her research suggests that resistance-training programs can improve cognitive functions more than aerobic exercise. In one study, she found that elderly individuals who took part in regular resistance training improved more in attention and working memory than individuals who took part in regular aerobic training.
While it isn’t yet clear why resistance training benefits working memory, other studies have found the same connection. So start hoisting some barbells and dumbbells, and you’ll be improving both your brain and your brawn.
