BOGOTÁ, Colombia — Are you too busy to exercise during the week? Scientists have good news: weekend workouts may be just as effective at protecting your brain health as regular exercise Monday through Friday.
The study, which tracked over 10,000 adults for 16 years, found that “weekend warriors” who exercised just once or twice per week had a 25% lower risk of developing mild dementia compared to those who didn’t exercise at all. This reduction in risk was similar to – and even slightly better than – the 11% lower risk seen in people who exercised three or more times per week.
This discovery could be particularly meaningful for busy working adults who struggle to find time for regular exercise. The research suggests that cramming your weekly physical activity into the weekend could still provide significant protection for your brain as you age.
“To the best of our knowledge, the present study is the first prospective cohort study to show that the weekend warrior physical activity pattern and the regularly active physical activity pattern are associated with similar reductions in the risk of mild dementia,” the study authors, led by Dr. Gary O’Donovan from the University of the Andes, in a media release.
The study, published in the British Journal of Sports Medicine, is the first of its kind in Latin America to examine how exercise patterns affect dementia risk. While previous research has shown that physical activity can help prevent cognitive decline, most studies have been conducted in wealthy nations in Europe and North America.
The researchers followed 10,033 adults in Mexico City with an average age of 51. At the start of the study, participants were asked about their exercise habits and divided into three groups: those who didn’t exercise, “weekend warriors” who exercised once or twice weekly, and regularly active people who exercised three or more times weekly.


After 16 years, participants took a standard cognitive test called the Mini Mental State Examination (MMSE) to assess their mental function. The results showed that both weekend warriors and regular exercisers performed better on the cognitive tests compared to non-exercisers.
Perhaps most striking was the finding that if all middle-aged adults exercised at least once or twice per week, about 13% of mild dementia cases might be prevented. In Mexico alone, where dementia costs nearly $3.8 billion annually, this could translate to savings of about $378 million per year.
The findings are particularly relevant given that dementia cases are expected to surge from 57 million globally in 2019 to 153 million by 2050. In Latin America, the number of people living with dementia is predicted to triple by 2050.
Paper Summary
Methodology
The researchers recruited participants through door-to-door interviews in two districts of Mexico City. They collected detailed information about exercise habits, education, income, blood pressure, smoking, body mass index, sleep patterns, diet, and alcohol consumption. Sixteen years later, they assessed cognitive function using the Mini Mental State Examination, which tests various aspects of mental ability, including memory, attention, and language skills.
Key Results
The average cognitive test score was 24.5 for non-exercisers, compared to 25.8 for weekend warriors and 25.6 for regular exercisers. When defining mild dementia as a score of 22 or lower, 26% of non-exercisers met this criterion, compared to only 14% of weekend warriors and 18.5% of regular exercisers. These benefits were similar for both men and women.
Study Limitations
Exercise habits were self-reported rather than measured objectively with devices like fitness trackers. Additionally, the cognitive test used can screen for dementia but isn’t a clinical diagnosis. The study also couldn’t account for physical activity from daily tasks like walking for transportation, which is common in Latin American cities.
Discussion & Takeaways
The study suggests that exercise’s brain-protective effects might work through several mechanisms, including increasing brain-derived neurotrophic factor (a protein that supports brain cell growth) and improving brain plasticity. The findings are particularly relevant for cities like Mexico City, which closes 50 kilometers of roads to vehicles every Sunday for their “Ciclovía Recreativa” program, allowing around 80,000 people to walk, run, or cycle safely.
Funding & Disclosures
The study was approved by the Mexican Ministry of Health, the Mexican National Council of Science and Technology, and the Central Oxford Research Ethics Committee. The data came from the Mexico City Prospective Study, which makes its data available for open-access requests through Oxford University’s Clinical Trial Service Unit.

Foundation Friday: Building bright futures & mental health through fitness
InnerCity Weightlifting volunteers find a sense of fulfillment by helping clients improve their fitness.
When people think about treating or managing their mental health, therapy, journaling and reading are often among the first solutions that come to mind. While those are all valuable tools, one of the most effective outlets is often overlooked: physical fitness.
At the Lift US Foundation, based in Oakland, leaders emphasize the mental benefits of exercise for adolescents through a strength-training-focused approach. Through its partnership with the NBA Foundation, the organization has expanded its efforts to empower young people and, as founder Mike Jenkins describes it, “create superheroes.”
“The need in the community is very foundational about strength and health in general, physical and mental,” Jenkins said. “I locked in on a term I like to call generational health, and what that means is the young people in our program become the healthiest in their families, and they take those values going forward in their own.”
As for InnerCity Weightlifting, which is based in Boston and Chicago, the organization uses personal training to help people affected by systemic barriers and past challenges build a new path forward. The nonprofit helps individuals with histories of gang involvement earn personal training certifications before connecting them with paying clients.
Though some people may not want to pursue personal training full-time, ICW still provides them with fitness tools they can carry throughout life while also helping guide their next steps into the workforce.
“Learn how to work out safely, learn how to give your friends a workout and then tell us what you need, what kind of jobs you’re interested in, what’s holding you back from some stability,” said ICW’s head of development Ian Kilpatrick.
Fitness to opportunity
From the ground up, Lift US focuses on teaching young people how to understand their bodies through fitness, nutrition education, counseling, mentorship and mental health support, all while helping them develop a future-focused mindset beyond the program.
Seeing a program participant progress through each phase and ultimately succeed is Lift US’s ultimate goal.
Rucker Johnson Jr. joined the organization at age 10 with a passion for science, art and drawing. Over time, he developed a love for weightlifting as well, eventually earning a spot on Team USA and setting his sights on representing the country at the 2028 Olympic Games.
“A complete human. A complete person, physically strong, mentally strong, academically strong, and not relying on getting a football or baseball scholarship. They are just doing it to empower themselves,” Jenkins said.
Johnson Jr. also branched out to the Hidden Genius Project, an Oakland-based nonprofit that trains and mentors young Black men in technology, entrepreneurship, and leadership. The organization has partnered with the NBA Foundation for several years.
Job pathways beyond fitness
As mentioned before, ICW ultimately helps place participants into jobs even outside the fitness industry, with their interactions with clients playing a key role.
The organization has seen numerous trainers transition into different industries simply by networking and performing well with the people they train. “We had guys get jobs at Toyota because a training client was a manager at Toyota, we’ve had a client start a dog grooming business and hire her trainer as one of the first employees,” said Kilpatrick.
The organization also builds partnerships with corporations such as UPS and Home Depot to streamline job pathways for participants.
Looking ahead, ICW is also focusing on creating more in-house managerial roles for participants who may not want to become full-fledged trainers. Either way, the organization provides volunteers with a sense of belonging and direction that helps them rebuild stability in their lives.
At their core, both organizations aim to build belonging and long-term success through fitness, which is a great place to start.

Alexandra Daddario, 40, Relies on This Underrated Crunch Upgrade for Strong Abs – Here’s How to Do It Properly
From enduring some serious physical prep for Baywatch to working consistently with elite trainer Patrick Murphy, Alexandra Daddario’s dedication to fitness is well-documented. She often shares insights on social media, and in a recent Instagram post, the White Lotus star gave an insight into how she trains her core with one powerhouse movement: the reverse crunch into shoulder stand.
Why is it so good? Most traditional ab exercises require repetitive spinal flexion—the process of pulling your chest down toward your knees, like in a standard crunch. This isolates only the upper section of your abs, and for women who spend hours sitting at a desk, it can reinforce a slouched, rounded posture.
Daddario’s movement flips the mechanics entirely since you actively curl your pelvis up toward your chest. In doing so, you target not only your upper abs, but the lower portion and your obliques (the sides) simultaneously, all while keeping your chest open and your neck unstrained. This translates into a much stronger core, better posture and crucial lower back protection. Research also shows that a controlled posterior tilt – the lower-body curl that initiates Daddario’s move – recruits a significantly higher percentage of deep core muscle fibers than traditional crunches.
Daddario then drives her hips directly up into a vertical shoulder stand. This completely removes momentum from the equation (meaning you can’t “cheat”) and forces your abs—particularly your obliques—to balance your body and prevent you from tipping sideways.
She then takes it one step further into a Pilates plow position with her legs overhead, before reversing the movement and, again, using her abs to control the lowering of her entire lower body as she slowly unrolls her spine down onto the mat. The plow portion is optional (and super advanced); the slow, controlled, lowering phase, which happens whether you move into plow or not, is where the magic happens, challenging your core through both lifting and resisting gravity. Inspired? Here’s exactly how to do the move with good form, and how many reps and sets to aim for.
How to do a reverse crunch into shoulder stand
- Lie on your back (either on a mat, or on a reformer Pilates machine, like Daddario, with your arms anchored tightly to the floor.
- Engage your core to curl your knees toward your chest, then fluidly press your feet straight up toward the ceiling, lifting your hips and lower back off the floor.
- Slowly lower down, one vertebra at a time. Aim for 3 sets of 6-8 controlled reps.
Optional progression:
- As you reach shoulder stand with your legs extended to the ceiling, slowly start to lower your toes toward the floor over your head. Your weight should rest entirely on your shoulders and upper back – not your neck.
- Keeping your legs straight, use your core to extend them straight back up to the ceiling, then control the descent by rolling your spine down one vertebra at a time, with your legs remaining straight.
