Forget what you think you know about brain health! While cardio has long been hailed as king, a longevity expert is now saying that resistance training might actually be the best exercise for your brain, potentially even slowing down age-related cognitive decline.
We’ve all been told that our brains, just like our bodies, need regular exercise to stay sharp. For years, aerobic exercise – think running, cycling, or brisk walking – has been considered the ‘gold standard’ for staving off cognitive decline. The reasoning was simple: cardio boosts heart function and increases blood flow to the brain.
But here’s where it gets controversial… Recent research suggests that while aerobic exercise is undoubtedly beneficial, it might not be the most effective way to keep your brain firing on all cylinders. So, what’s the real magic bullet for cognitive health?
The answer, increasingly, appears to be resistance training. A growing body of evidence is highlighting resistance training – whether through weightlifting, using resistance bands, or other strength-building activities – as a powerful boost for brain health and memory. Dr. Austin Perlmutter, a leading longevity expert, is at the forefront of this shift in thinking.
For decades, we’ve been encouraged to focus on cardio for brain health. Walking, running, cycling – these activities were thought to be the key because they improve heart function and, crucially, increase blood flow to the brain.
Lately, however, research is shining a spotlight on another type of exercise. Resistance training, encompassing activities like lifting dumbbells or using resistance bands, seems to have an even stronger and more profound effect on memory and cognition. This is particularly true for older adults and individuals showing early signs of cognitive decline. And this is the part most people miss: the way you move your body profoundly impacts the health of your brain.
Recognizing this shift in understanding gives us a valuable opportunity to proactively protect our brains as we age. It’s about more than just physical strength; it’s about building a resilient and sharp mind.

So, how exactly does resistance training benefit the brain? Multiple investigations, including a notable study highlighted by Alzheimer Europe, have demonstrated that resistance training enhances memory, attention, and decision-making abilities. The key takeaway is that it does so effectively, either more so than, or at least on par with, regular aerobic exercise.
In a landmark randomized controlled trial, older women who participated in just one or two resistance training sessions per week showed significant improvements in selective attention and conflict resolution – both crucial components of executive cognitive function.
A separate study involving adults with cognitive impairment, published in Frontiers in Neuroscience, revealed that resistance training helped preserve brain volume in memory-critical regions, such as the hippocampus. This, in turn, slowed down the pace of cognitive decline. To illustrate, imagine the hippocampus as the brain’s filing cabinet for memories. Resistance training appears to act like a protective coating, preventing the cabinet from deteriorating and ensuring that memories are properly stored and retrieved.
These effects are particularly important because cognitive impairment often responds poorly to traditional medical treatments, making preventative measures like resistance training all the more crucial.
Why Hitting the Weights Could Be Your Brain’s Best Friend
Weightlifting triggers the release of vital chemicals in the brain, including brain-derived neurotrophic factor (BDNF) and insulin-like growth factor-1 (IGF-1). Think of these as fertilizer for your brain cells; they nurture the growth and repair of neurons, the building blocks of the brain.
At the same time, resistance training helps to reduce inflammation throughout the body and brain. It also aids in clearing away the toxic protein clumps that are associated with Alzheimer’s disease. Imagine it as a cleaning crew, sweeping away debris that can clog up and impair brain function.
By building muscle, resistance workouts also increase blood flow to the brain, which further protects brain tissue and helps prevent the shrinkage of memory-related regions.
In short, strengthening your muscles seems to send the right signals to the brain, making resistance training a powerful form of brain protection. It’s like giving your brain a regular tune-up!
Even Helpful in Those Already Diagnosed
Resistance training isn’t just a preventive measure; it can actually sharpen memory even in individuals already exhibiting signs of cognitive decline. This is a crucial point to understand.
Studies involving older adults with cognitive impairment have shown that just a few months of resistance training can lead to noticeable gains in both memory and verbal fluency. The exercise appears to shield brain regions from further degeneration, offering a drug-free way to slow down the progression of dementia.
For patients and their caregivers, this represents an incredibly hopeful discovery, offering a tangible way to improve quality of life and maintain cognitive function.
Mixing Up with Cardio
Even though resistance training is finally gaining the recognition it deserves, combining it with cardio work appears to be the ideal brain-boosting combination. Think of it as a synergistic effect – the whole is greater than the sum of its parts.
Several studies have reported that people who incorporate both weightlifting and cardio into their routines experience improved memory and clearer thinking compared to those who stick to cardio alone. Cardio revs up the heart and lungs, improving overall cardiovascular health, while strength work builds muscle and stimulates the brain’s repair mechanisms. A balanced routine that blends both seems to be the perfect recipe for keeping the brain in top shape as we age.
How to Start Strength Training
Starting a resistance training routine can be surprisingly straightforward and safe for most adults. You don’t need expensive equipment or a gym membership.
Simple exercises can be done at home using your own body weight (think squats, push-ups, and planks), a set of resistance bands, or a few light dumbbells. Focus on working the core muscle groups – legs, arms, back, and core. Aim to fit in two moderate-intensity resistance training sessions each week, gradually increasing the weight or resistance as your strength improves.
Important note: If you have any underlying health conditions, it’s always wise to consult with a qualified trainer or healthcare professional before beginning any new exercise program. They can help you create a safe and effective routine tailored to your individual needs.
Remember, consistency is absolutely essential for reaping all the cognitive benefits of resistance training. It’s not about occasional bursts of effort; it’s about making it a regular part of your lifestyle.
