The #1 Activity to Boost Your Memory, According to Doctors

You walk into a room and forget why you’re there. Names evaporate right after introductions. We’ve all been there before. It’s frustrating, yes, but it doesn’t mean inevitable decline—especially if you make an effort to train your brain. 

Two clinicians who specialize in cognitive health point to a single, evidence-based habit that boosts memory without pricey pills or complex routines: structured cognitive training, also called “brain training.”

“Brain health isn’t something you buy; it’s something you build,” says D. Ivan Young, Ph.D., MCC, NBC-HWC. “It’s often the smallest, most consistent changes that deliver the biggest results.” Cognitive training focuses on active strategies—like self-quizzing and regular practice—to strengthen your memory over time. Keep reading to learn the science behind cognitive training and how to get started today.

Why Cognitive Training Is the Best Activity for Better Memory

“What gives me hope and what I see in both research and my coaching practice is how adaptable the brain truly is,” says Young. “Cognitive training remains one of the most effective tools for strengthening memory. Thankfully, it doesn’t require flashy tech or long hours. It’s simply about being intentional.”

Cognitive training is not a passive process—like rereading or highlighting notes—but instead involves deliberate, structured practice, Young explains. It involves active retrieval of information (like quizzing yourself), spacing out learning (reviewing material over time) and interleaving (mixing topics). Together, these methods strengthen the brain’s pathways for storing and retrieving information. Here’s why it works.

It Helps Your Brain Retrieve Information More Efficiently

Every day, we rely on our brain to recall information—whether it’s a name, a fact or the storyline of a favorite movie. Cognitive training helps the brain retrieve stored memory more efficiently, but it only works with consistent challenges over time.

Young compares it to training at the gym: watching someone lift doesn’t build muscle—resistance does. Retrieval practice provides that “resistance” for your brain. This can include activities like quizzing yourself on new facts or vocabulary, explaining a concept to someone else from memory, mentally recalling events from your day or practicing mental math instead of using a calculator. 

The key is to train your brain regularly over the long term. Research in older adults shows that spacing out learning beats cramming, leading to a stronger recall even a month later. To retain information, it’s best to learn and review gradually over time.

It Strengthens Your Brain Through Gradual, Targeted Practice

Gediminas Gliebus, M.D., says the key is to challenge your brain regularly, track your progress and notice how these activities make everyday memory tasks easier.

Done right, cognitive training uses “just-hard-enough” difficulty with measurable progression. You should challenge yourself so that the task isn’t easy, but still achievable with some effort. As you improve, continue to increase the difficulty. Young recommends 15- to 30-minute sessions a few times per week as a sustainable and effective routine. For example, you may play strategy or puzzle games that gradually become harder as you advance through levels.

For an added challenge, combine mental exercises with light physical movement—like walking while mentally rehearsing a list—which can further support memory in older adults. “As I often remind my clients, the brain and body are in constant communication,” says Young. “When you take care of one, you support the other.”

It Provides Lasting Results

“Training can have lasting benefits, not just quick fixes,” says Gliebus. If you put in the work, you can see lasting results that apply to various areas of your life.

For instance, a five-year study in older adults found that those who trained their memory regularly maintained stronger thinking skills compared to those who didn’t. This suggests that cognitive training can deliver long-term, meaningful results for your memory.

How to Incorporate It into Daily Life

• Pick a Focus. To start, identify an area you would like to improve on, such as remembering names, retaining new information or recalling information quickly. Then, choose a form of training that supports it. For example, face-name associations using flashcards, quizzing yourself after learning a new topic, or “spot the difference” puzzles.
• Use Retrieval, Not Review. When learning something new, take a moment to retrieve the information you just learned. For example, close the book you’re reading and quiz yourself, or try teaching the material to someone else out loud. Young likens retrieval to the “resistance” that strengthens memory traces.
• Spread It Out. Start with 15 to 30 minutes, three times per week. “Aim for short sessions three times a week, ideally when you feel most alert,” says Gliebus.
• Continue to Challenge Yourself. When recall feels easy—high accuracy with little effort—it’s time to increase the difficulty. This may include recalling longer lists, choosing harder puzzles or learning more complicated topics. 
• Leverage Simple Strategies. “Practicing memory tricks like visualization or storytelling works because you’re actively recalling, not just rereading,” says Gliebus. “For example, if you’re trying to remember a grocery list, picture the items in your kitchen or make up a story that links them together. Consider puzzles, learning a new skill like a language or instrument, or playing strategy games like chess, too.”
• Include Other Healthy Habits. Combining brain exercises with other healthy lifestyle habits—such as exercise, healthy eating and quality sleep—has been shown to further support memory, attention and cognitive function in older adults.
• Set Reasonable Expectations. Remember that results take time—cognitive training improves the skills you practice most, and broader day-to-day benefits may take several weeks or months to appear.

When to See a Health Care Provider

Forgetting where you put your keys, having trouble recalling someone’s name or briefly losing track of why you walked into a room are all normal parts of aging. “These kinds of lapses typically don’t interfere with daily life, and most people experience them from time to time,” says Gliebus. “What’s more concerning is when memory problems happen often, keep getting worse or interfere with everyday routines.”

Gliebus says red flags include forgetting meaningful conversations, missing bills or medications, or struggling to manage daily tasks. “If memory issues are affecting independence or are paired with problems in reasoning, judgment or language, it’s a good idea to get checked by a health care provider.”

Our Expert Take

Improving memory takes deliberate effort, and cognitive training is one of the most effective ways to do it. By challenging your brain in a structured, progressive way, you strengthen everyday memory skills. Start small, stay consistent and gradually increase the challenge. Mixing different exercises can keep your training engaging and help target multiple aspects of memory. Over time, you’ll notice improvements in real-life tasks—like remembering names, appointments and details from conversations. It’s not a quick fix, but with patience and practice, cognitive training delivers lasting results—no pills, gadgets or expensive programs needed. Your brain is capable of growth, and consistent effort lets you unlock its full potential.
