Can Strength Training Protect Your Brain?

What if one of the most effective ways to protect your brain was hiding in the weight room? Recent research reveals that it might be true — regular resistance training could be key to maintaining cognitive health and potentially delaying or reducing the onset of cognitive decline.

In a new study, scientists explored how different types of training, including brain exercises and resistance workouts, impact adults over 55. The results were clear: weight training serves as a powerful shield for the hippocampus, the brain’s memory and learning hub. Preserving the health of this area is crucial for resisting cognitive decline and warding off conditions like dementia.

How does resistance training achieve this? It appears to enhance "hippocampal plasticity" — the brain’s ability to adapt and form new connections, which is essential for sustained cognitive health. Moreover, additional studies suggest that strength training can reduce amyloid plaques, which are linked to Alzheimer’s disease.

So, how much time do you need to invest in strength training for brain benefits? The participants in the study gained cognitive protection from just 90 minutes of resistance training per week, spread over two to three sessions.

Adding regular strength training to your routine can benefit both your body and your brain, helping you stay sharp as you age.
