Most of us are well-aware of the benefits training and regular exercise have on our body, but we often overlook the connection between regular physical activity and our brain.
Dr. Kim Johnson Hatchett, a neurologist, explains that the lack of physical activity, especially strength training, affects the brain negatively and the damage caused can be lasting.
Dr. Hatchett, who is also a public speaker and has nearly 9,000 TikTok followers, took to the social media to remind people to stay active for the sake of their brains. In a recent post, she explained, “The scariest thing I see as a neurologist is the gradual weakening of America. Not moving your muscles . . . has an effect on every aspect of your life and most importantly your brain.”

In an interview with Self, Dr. Hatchett said that not many people are aware of the strong link between physical activity and their brain.
“Every time you exercise, you secrete nerve growth factor, a peptide involved in regulating neurons in the brain,” she explained. “It can also support myelin, the neuroprotective sheath that helps nerve fibers shuttle electrical impulses quickly and efficiently and can degenerate with age.
“So many of my patients are frustrated by their lack of mobility. I ask them about their activity level, and they often admit they aren’t really exercising at all.
“They truly don’t make the connection that their weakness is due to their lack of muscle movement, and they definitely are unaware of the impact that it might be having on their brain.”
She pinpoints that even slightest daily movement may reduce the risks of dementia.
During exercise, particularly cardio and strength training, the blood flow to the brain increases, leading to better cognitive functions.
“If you want to maintain your mobility and cognitive abilities, one investment you can make is exercising and using your muscles on a daily basis.
“That pop of [nerve growth factor] will just help your brain function better.”
Dr. Hatchett concluded that we are all the sailors of our own ship.
“Ultimately, what I wish people knew is that you have more control in the aging process than you realise!
“Getting weaker as you age is not inevitable and regular exercise and strength training will pay off in dividends in the end.”
