It’s no secret that staying active benefits the body. What often goes unnoticed, however, is how essential movement is for the brain. Far too often, this connection is overlooked. According to neurologist Dr. Kim Johnson Hatchett, the most unsettling trend she encounters is the growing tendency to neglect physical activity, particularly strength training. The consequences of this seemingly small oversight are more profound than many realize.
Muscle Weakness and the Brain: An Unseen Link
A common complaint in doctor’s offices involves physical weakness or mobility challenges. But few patients suspect that these issues could be affecting their brain health as well. Through social media platforms like TikTok, Dr. Hatchett has been vocal about this connection. The absence of regular movement, especially exercises that challenge the muscles, reduces the body’s production of nerve growth factor (NGF). NGF plays a pivotal role in supporting neurons and the protective sheath called myelin, both of which are critical for maintaining sharp cognitive function. Without it, the brain becomes more vulnerable to decline.
The Modern-Day Inactivity Trap
In today’s world, convenience and comfort often take priority. Long work hours, endless screen time, and sedentary leisure activities dominate many lives. Exercise becomes an afterthought, frequently sacrificed for tight schedules or perceived lack of time. This pattern, seen most commonly in people during their 30s and 40s, paves the way for health concerns down the road. Dr. Hatchett emphasizes that even brief daily movement can significantly lower the risk of dementia and other cognitive challenges.

What Happens Inside the Brain When You Move
Each time the body engages in exercise, whether through cardio or resistance training, the brain responds in remarkable ways. Increased blood flow delivers oxygen and vital nutrients, enhancing mental clarity and focus. Learning a new physical skill, like a sport or dance routine, forces the brain to forge new neural pathways. Repetition of these activities strengthens those connections, enhancing memory, coordination, and resilience.
Why Strength Training Matters More Than Ever
Aging naturally leads to a reduction in muscle mass. This decline becomes more noticeable after age 50. Without regular strength training, muscle atrophy accelerates, making everyday tasks feel more demanding. Simple actions like lifting groceries, climbing stairs, or walking longer distances can become burdensome. Dr. Hatchett consistently highlights the importance of incorporating strength-based exercises into daily routines. This practice not only supports mobility but also plays a crucial role in preserving mental sharpness as the years go by.
Muscle Mass and Longevity
Studies show that higher muscle mass correlates with increased lifespan and a lower risk of chronic diseases. When muscle deteriorates, it impacts metabolism, balance, and even mental well-being. Maintaining strength isn’t about vanity; it’s about creating a stable foundation for a long and healthy life.
Exercise as a Preventive Medicine
Just as medications are prescribed to prevent illness, physical activity can serve as preventive medicine. Building strength safeguards the brain from cognitive decline. Cardiovascular exercises support heart health and improve mood, while resistance training keeps the brain engaged and strong. The body’s systems thrive when movement becomes part of daily life.
The Emotional Benefits of Movement
Exercise is not only beneficial for the body and brain but also crucial for emotional health. Physical activity triggers the release of endorphins and other feel-good chemicals, reducing stress, anxiety, and symptoms of depression. Regular movement fosters a more positive outlook, better sleep patterns, and heightened resilience against life’s daily challenges.
Starting Small: The Key to Long-Term Success
There’s no need to commit to extreme workouts. Small steps, taken consistently, are what matter. Bodyweight exercises, gentle yoga, resistance bands, and light dumbbells are excellent starting points. Consistency builds confidence and leads to gradual progress, with long-term benefits for both the brain and body.
Aging Doesn’t Have to Mean Decline
Dr. Hatchett’s core message is simple: getting older does not have to mean becoming weaker. Physical decline is not an unavoidable part of aging. By taking proactive measures today, individuals can safeguard their independence and cognitive abilities for years to come.
The Role of Routine in Brain Health
Building habits around movement makes it easier to maintain momentum. Scheduling exercise, setting achievable goals, and celebrating small victories all contribute to a healthier routine. Movement becomes a part of life, rather than a chore.

The Science Behind It All
Research has consistently confirmed the link between physical activity and cognitive health. Aerobic exercises have been found to increase the size of the hippocampus, the area of the brain associated with memory. Resistance training has been shown to enhance executive functions, including problem-solving, multitasking, and decision-making.
Strength Training Recommendations
Experts suggest engaging in strength-building exercises at least twice a week. Focused sessions targeting major muscle groups help maintain balance and coordination. Compound exercises like squats, lunges, and push-ups are especially effective. Rest and recovery are equally important to avoid strain and injury.
Common Excuses and How to Overcome Them
Time constraints, lack of motivation, and fear of injury often prevent people from exercising. However, short, focused workouts can fit into even the busiest schedules. Motivation can be bolstered by finding enjoyable activities and exercising with friends or groups. Starting slow and listening to the body helps prevent injuries and builds confidence.
Exercise at Every Age
It’s never too late to start. Seniors benefit from strength and balance training just as much as younger individuals. Adaptations can be made to accommodate physical limitations, ensuring safety and effectiveness.

The Financial Benefits of Staying Active
Medical expenses related to cognitive decline and mobility issues are significant. Investing time in exercise now can save substantial costs in the future. Fewer doctor visits, reduced need for medications, and a higher quality of life all stem from staying active.
Conclusion: Investing in the Future
Neglecting physical activity, particularly strength training, has been identified as one of the most harmful habits affecting brain health. Muscle weakness does not only lead to physical limitations but also poses risks to cognitive function. The good news is that this can be prevented. Regular movement strengthens both body and mind, creating a solid foundation for aging gracefully. As Dr. Hatchett wisely points out, getting weaker is not inevitable. The best time to take action is today.
