Health officials recommend at least 150 minutes of aerobic exercise per week and 2 sessions of resistance training, targeting each major muscle group.

Official recommendations state that healthy adults should perform progressive resistance training that increases weight and repetitions over time.

Adults need 2 days of muscle-strengthening activity weekly—yet most of us aren't doing that.

Resistance training is linked to better memory and cognitive function in older adults.

One minute of exercise correlates to five extra minutes of life (on average).

Recent global health estimates suggest that inactivity is a leading risk factor for death, contributing to 6% of deaths worldwide.

Discover how strength training may help your brain and what happens inside your cells when you work out with this original '1440 Explores' podcast.

Strength training appears to make for a healthier, youthful-looking brain.

Moving your body every day is key to longevity

In an era of biohacking, where millionaires subject themselves to draconian routines and tests to de-age themselves, one study suggests a super simple key predictor of mortality: more than any other trait, how much subjects moved determined how long they'd live. Movement mattered even more than age in predicting overall life longevity. Researchers suggest this means we should all simply get outside a bit more. Read more about the study here.

How endurance athletes can build resilience

Long-distance runners and other endurance athletes can improve their performances using tips explored in this article. Findings from two recent studies show that strength training, high-altitude training, and intense interval sessions are all potential methods for ameliorating long-term athletic capabilities.

Resistance training can help fight osteoporosis, especially in menopausal women.

The eight habits that could add up to 24 years to your life

A study presented at the American Society for Nutrition's annual meeting revealed that adopting eight healthy lifestyle habits in middle age can significantly increase life expectancy. The habits include being physically active, avoiding opioid...

Exercise can lead to muscle microtears, but the body's repair systems cause those fibers to grow back larger.

Astronauts exercise on the International Space Station

Astronauts maintain bone, muscle, and cardiovascular health with physical activity. It's crucial that they make time to exercise for approximately two hours per day. This resource offers a behind-the-scenes look at how high-intensity workouts help prevent muscle atrophy, bone density loss, and aerobic decline during monthslong space missions.

Health span: The number of years one is active and disease-free

As scientific advances continue to extend the average human lifespan, many are now turning their attention toward extending "health span." The ultimate goal would be to extend one's health span to match one's lifespan, which would necessitate a shift in focus toward the pursuit of healthy aging. (Some users may experience a paywall.)

Can fasting help you live longer?

Animal studies into the health benefits of calorie restrictions of 20%-40% suggest it extends life spans and reduces incidents of age-related diseases, including cancer. This article explores the research into fasting, calorie restriction, and longevity.

Strength training doesn't require fancy equipment—cans, water bottles, and shopping bags work well.

Doctors shift focus from extending lifespan to lengthening health span

As scientific advances extend the average human lifespan, many are turning their attention toward extending "health span." Health span refers to the number of years one is active and disease-free. The ultimate goal is to extend one’s health span to match one’s lifespan.

Explore how to safely start 'strengthmaxxing' with body weight—not actual weights.

Optimal human functioning requires movement

There is now ample evidence to back the centuries-old hypothesis that exercise is critical to human health. This review article explores the latest discoveries in exercise science, including how exercise is intrinsic to maintaining our organ systems throughout life.

Brain training game creates long-lasting changes in the brain that may help protect against dementia.

Overwork contributes to thousands of worker deaths

Can work really kill you? The World Health Organization and the International Labor Organization have estimated that long work hours contribute to thousands of death from strokes and heart attacks each year. This BBC article argues that the culture of overwork and burnout is leading to a public health crisis in desperate need of solutions.

Exercise improves brain blood flow, stimulates neural growth, and more.

Adults may lose roughly 3% of their muscle mass each decade after 30.

Exercise can change your genes without changing your DNA.

Grip strength, how firmly and securely you can hold onto things, predicts death better than blood pressure

Even brief physical activity can trigger the release of neurotransmitters that provide mental health boosts

A couple of minutes of light walking or stretching can increase feelings of energy and reduce fatigue, not just through the release of endorphins. Exercise can also provide self-regulation and improve task engagement and focus in those with certain mental health disorders, like ADHD.

Exercise causes diet-independent changes in the gut microbiome.

Just a 10-minute mental health break can yield benefits

The US CDC offers recommendations for alleviating stress in daily life. Short 10-minute breaks can significantly improve mental health, especially when used for activities like deep breathing, dancing, or writing down things you are grateful for. Building meaningful relationships, termed "social connectedness," can also alleviate stress and promote resilience.

Heat-related complications are of greater concern for distance runners than cardiac threats

Analysis of more than 130,000 runners in Tel Aviv events during a seven-year period indicated that the runners were 10 times more likely to experience heatstroke than serious cardiac problems. Scientists suggest that runners should take 10 to 14 days to acclimate to a hot climate before tackling a serious run.

Doctors are prescribing social activities—and seeing good results

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.

World records are often broken later in the day—and scientists wonder if muscle clocks explain the difference.

Extending the worldwide lifespan by one healthy year is worth $38T

This econometric study attempts to estimate the economic value of increasing the global healthy lifespan by one year—and to answer the question of whether it is better to extend lifespans or slow the rate of healthy aging.

Staying on standard time permanently would slightly reduce obesity and stroke risk

A 2025 study that examined time changes found that permanently changing to standard time would slightly reduce obesity and stroke risk more than switching to permanent daylight saving time.
