We are no longer exercising solely for physical fitness; our brains are now a significant focus of our workouts. The concept of “brain workouts” has gained immense popularity, amassing thousands of likes, saves, and comments across social media platforms. However, one question remains: Are these brain-boosting exercises scientifically sound, or are they merely another wellness trend designed to capture attention?
Recent studies have delved into this topic, revealing that exercise is crucial for maintaining brain health as we age. But does the type of exercise matter? Are some forms of physical activity more beneficial for cognitive function than others? We consulted three experts to uncover the truth.
Exercise: A Key to Brain Health
According to Dr. Tiana S. Woolridge, a sports medicine physician at the Hospital for Special Surgery in New York City, exercise offers remarkable benefits for both short- and long-term brain health. She explains that consistent physical activity can enhance memory, focus, decision-making, and processing speed within just a few months.
A 2025 metareview published in the British Journal of Sports Medicine supports this claim, having examined 258,000 individuals. The study found that even low- to moderate-intensity exercise performed for less than 30 minutes twice a week improved general cognition, memory, and executive function within one to three months.
“Even a single workout can improve your cognition,” Dr. Woolridge notes. “A quick workout before an important meeting or presentation can actually sharpen your performance.”
Long-term, regular exercise can significantly reduce the risk of developing brain diseases such as dementia. A 2025 study in the Journal of the American Medical Directors Association, which tracked nearly 90,000 adults over 4.5 years, found that as little as 35 minutes of moderate-to-vigorous exercise each week lowered the risk of dementia by 41 percent.
The Science Behind Exercise and Brain Chemistry
Physical activity directly alters the brain’s chemistry and structure. Dr. Woolridge explains that exercise stimulates the release of brain-derived neurotrophic factor, which promotes the growth of new blood vessels and neurons. It also triggers molecules that reduce inflammation and protect brain cells while boosting neurotransmitters like dopamine and serotonin.
Dr. Woolridge adds, “Brain scans show that people who exercise regularly can have stronger, healthier brain tissue and better brain function.”
Notably, physical activity in early life is linked to better cognitive function in later years. However, starting exercise later in life still offers significant brain benefits, with older adults often experiencing the most dramatic cognitive improvements.
Different Exercises, Different Benefits
While all forms of exercise benefit the brain, different types target specific cognitive skills. Dr. Emerlee Timmerman, an assistant professor of clinical neurology at the University of Cincinnati College of Medicine, highlights aerobic exercise as particularly effective for boosting cognition and memory.
“Overall, we typically recommend aerobic exercise like walking, running, or cycling for enhancing cognition and memory,” says Dr. Timmerman.
Resistance training, on the other hand, is essential for mental control. It has been shown to improve global cognitive function and the ability to suppress impulsive behaviors.
Mind-muscle exercises like yoga are ideal for learning and focus. Dr. Patrick Fratellone, a cardiologist and integrative medicine doctor in New York City, notes that yoga increases gray matter in the brain, enhancing neuron communication, boosting blood flow, and expanding the hippocampus, which is crucial for learning and memory.
Maximizing the Brain Benefits of Exercise
Even if brain health is not your primary motivation for working out, incorporating certain qualities into your routine ensures benefits for both body and mind. Dr. Woolridge emphasizes that even modest amounts of exercise can provide significant cognitive benefits.
“The relationship between exercise dose and brain health is more nuanced than ‘more is better,’” she says.
To maintain memory long-term, regular exercise is more beneficial than sporadic activity. Dr. Fratellone and Dr. Timmerman recommend at least moderate-intensity exercise on as many days as feasible, aligning with guidelines from organizations like the World Health Organization and the American Heart Association.
Moreover, achieving around 10,000 steps per day offers the most protection from dementia, but even 4,000 steps daily provide substantial benefits. Purposeful, brisk walking is more protective than casual strolling.
Exercise should be part of a comprehensive lifestyle approach to protect brain health, including healthy eating, brain training, and heart health monitoring. A study in Finland involving 1,200 older adults showed that combining these factors improved cognitive skills by 25 percent over two years.
“Exercise is one of the most powerful tools we have for maintaining brain health across the lifespan,” Dr. Woolridge concludes. “But think of it as one essential component of a comprehensive brain health strategy.”
