How to train your brain like your muscles, according to a neurologist

"It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity, and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles."

"Think about walking the same loop through a local park every day. At first, your senses are alert. You notice the hills, the trees, the changing light. But after a few loops, your brain checks out. You start planning dinner, replaying emails, or running through your to-do list. The walk still feels good, but your brain is no longer being challenged. Routine feels comfortable, but comfort and familiarity alone do not build new brain connections."

The brain strengthens cognitive abilities through progressively increasing mental challenge in the same way muscles grow with progressive resistance. Clear thinking, focus, creativity, and judgment improve when the brain is asked to stretch beyond routine rather than run on autopilot. Repeating the same familiar actions reduces sensory engagement and stops building new neural connections. Slight mental discomfort signals productive cognitive training. Regular routines feel comfortable but do not by themselves create new brain pathways. Electroencephalogram recordings show dynamic rhythms that become more organized and coordinated when someone learns a new skill, reflecting strengthening of pathways needed for that skill.
