Does exercise sharpen your memory? How long do the benefits last? New research
Most of us have forgotten where we put our phones or car keys or what we ate for dinner last night. We’ve walked into a room and wondered why we even walked in there in the first place. A sharper memory helps us retain the information we’ve learned and remember what’s important. We’re always hearing about this superfood or this special drink or supplement that can boost memory, and we wonder if there’s any merit to many of these claims.
With all the benefits of exercise, from lowering blood pressure to perking up your mood, researchers wanted to explore if exercise could boost memory and how long these benefits last. If working out is effective, how many hours or days do those short-term cognitive benefits last? Does working out the day before improve your memory the following day? Let’s look at the new research.
The study
In a small study published in the International Journal of Behavioral Nutrition and Physical Activity, researchers analyzed data from 76 adults. Participants were aged 50 to 83. Over eight days, participants took daily cognitive tests and wore activity trackers.
The results
Researchers revealed that participants who engaged in more moderate to vigorous physical activity performed better in memory tests the following day. The adults who had better scores on the memory tests:
Moderate activity can include brisk walking, cycling, or jogging. Participants who spent more time being sedentary performed worse on the tests.
Previous research
This isn’t the first study to associate exercise with a better memory, and it certainly won’t be the last. Research has shown that moving your muscles enhances your neuronal activity, which refers to the chemical and electrical signals generated and transmitted by neurons in your brain. Previous studies found that people had better results on memory tests in the hours following exercise, but researchers weren’t sure how long these positive effects stick around.
Interestingly, researchers in one study determined that high-intensity interval training or HIIT and cycling were the types of exercise most likely to enhance memory, executive function, attention, and information processing.
Why does exercise improve recollection and cognition?
Researchers and experts believe exercise can improve memory and cognition by increasing blood flow and stimulation of neurotransmitters. Neurotransmitters help transmit messages between nerve cells to assist memory and thinking. Exercise can also prompt the hippocampus to form new neurons. The hippocampus in your brain plays a big role in your learning and recollection.
Neuroplasticity of the brain
Research highlights that exercise promotes neuroplasticity in the brain. Neuroplasticity refers to your brain’s ability to adapt and form synaptic connections, particularly in response to learning, experience, or after an injury.
The takeaway
Spending less time sitting and getting a minimum of 6 hours of sleep every night is beneficial for your mental faculties and overall health. If you get a good workout in the day before, your mind and memory could be sharper the following day. It turns out that working out really could enhance your memory, at least for the next 24 hours, which is worth keeping in mind if you have a big presentation or test coming up. The research is mounting.

Fitness coach says ‘just cardio isn’t enough’; shares 1 exercise women over 35 must do to stay strong and healthy
As we age, our bodies naturally start losing muscle mass and bone density, which can affect strength, metabolism, and overall health. Many women over 35 notice changes in energy levels, weight distribution, and endurance, making it essential to adopt exercises that not only tone but also strengthen the body.
Tara LaFerrara, fitness coach and personal trainer, shares in her September 22 Instagram post why women over 35 should start incorporating strength training into their routines and how it can transform both body and health.

Why does muscle loss matter after 35
If you are a woman over 35 and not doing any sort of strength training, Tara warns you’re in for a rude awakening. “I’m talking the moment that your body starts to slow down, get weaker, and feel like you hurt more,” she shares.
“It is not just ageing, it is muscle loss, and it starts way earlier than you think. After the age of 35, we start losing muscle every single year. And that muscle is so important because it is your metabolism, your bone density, your energy, and just the ability to bounce back when life throws things at you,” says Tara.
Can cardio and pilates alone keep you strong
She emphasises that cardio and Pilates alone aren’t enough. “You need to lift, squat, push, pull, and press. It’s not about getting bulky and muscular, it’s about getting strong enough to handle ageing on your own terms.”
Her advice is simple: “So if you’re tired of feeling like your body is working against you, start working with it. Pick up some weights. Your future self will thank you.”
Strength training after 35 isn’t just about aesthetics; it’s about maintaining health, mobility, and resilience. As Tara highlights, incorporating resistance exercises into your routine is one of the best ways to support your body through the natural changes that come with age.

New Year’s Fitness Resolutions Start with Healthy Sleep | Newswise
Newswise — As the New Year approaches, many Americans are setting fresh intentions to eat better and move more — and new data show those habits may deliver an unexpected bonus: better sleep. According to a new survey from the American Academy of Sleep Medicine, 59% of adults say eating a well-balanced diet helps them sleep slightly or significantly better. Staying active throughout the day may also help improve sleep. According to the survey, adults say exercising in the morning (42%) or evening (46%) helps them sleep slightly or significantly better.
“Sleep is one of three pillars of a healthy lifestyle, including eating a well-balanced diet and incorporating regular physical activity,” said AASM spokesperson Dr. Kin Yuen. “When people make New Year’s resolutions or select their ‘nudge word’ for the year, they often prioritize diet and exercise. These changes don’t just support physical health—they also improve sleep.”
The findings suggest that New Year’s resolutions don’t need to be isolated goals. Improving one aspect of health, whether diet, exercise, or sleep, can create positive ripple effects across all three areas of wellness. This is especially true for younger adults, with those 25-34 being the most likely age group to say a well-balanced diet (64%) or exercise in the evening (60%) helps them sleep better.
“Sufficient sleep significantly reduces the risk of chronic illnesses, such as obesity, heart disease, and even depression and anxiety,” said Yuen. “Whether you’re improving your diet, increasing your activity level, or managing stress, prioritizing sleep gives you the energy and mental clarity needed to start the year strong.”
Here are some tips from the AASM on how to develop healthy sleep habits and reap all the benefits of your New Year’s resolutions:
- Create a consistent bedtime routine — Make sure you are giving yourself enough time to get the recommended seven or more hours of sleep per night.
- Make time in your daily routine for physical activity — Pick physical activities that you enjoy and that match your abilities.
- Eat a well-balanced diet — Try to meet the recommended daily servings of fruits and vegetables, grains, and protein.
- Disconnect from devices at night — Turn off all electronics at least 30 minutes to an hour before your bedtime to help prepare for sleep.

About the Survey
The American Academy of Sleep Medicine commissioned an online survey of 2,007 adults in the U.S. The overall margin of error fell within +/- 2 percentage points with a confidence interval of 95 percent. Fieldwork took place between June 5-13, 2025, by Atomik Research, an independent market research agency.
