exercise

Building muscle doesn’t have to mean exhausting workouts or soreness. Researchers found that slow, controlled “lowering” movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like chair squats or wall push-ups can make a real difference. It’s a smarter, easier way to get stronger—no gym required.

The brain is more mechanically connected to the body than previously appreciated, scientists reported in Nature Neuroscience, noting the connection could be a potential biological mechanism underlying why exercise is thought to benefit brain health.

New research suggests that sustained exercise may quietly reshape the biology of stress. In a first-of-its-kind clinical trial published in the Journal of Sport and Health Science, researchers explored how a year of aerobic exercise affects the biology of stress and emotion. The randomized study focused on long-term physiological changes linked to regular physical activity. [...]

By tracking healthy adults over 12 months, researchers found that regular cardiovascular workouts lead to a drop in systemic cortisol. This reduction suggests physical activity provides a biological buffer against chronic stress.

In exercise and workout for the purpose of losing weight. Isn't it that the glycogen in the liver takes 20 hours to deplete. Must one deplete glycogen storage first before fat burning in cells would be utilized? But I read conflicting reports that even without depleting glycogen storage, fats... Read more

Nature, Published online: 17 April 2026; doi:10.1038/d41586-026-01245-w Study in mice suggests that B cells help regulate muscle performance.

Many people underestimate the importance of sleep, thinking it is simply a time when the body shuts down. In reality, sleep is a highly active process that keeps the body healthy. A new study from the University of California, Berkeley, published in Cell, reveals how the brain controls growth hormone during sleep and why this […] The post Deep sleep could help build muscle, burn fat, and boost br…

Musculature, strength, size, and endurance are maintained only so long as they are demanded. The moment that demand disappears, the physiological mechanisms that once built muscle now work towards energy conservation, initiating a gradual, though measurable, decline

Scientific study has extensively corroborated the advantageous impacts of exercise on mood, cognitive function, and stress resilience. Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the “Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Functi…

Researchers have identified a molecular mechanism that helps explain why exercise remains so effective in maintaining muscle health with age. Scientists have identified a molecular switch that may help explain one of the biggest benefits of exercise as people grow older: the ability to keep muscles repairing themselves. A research team at Duke-NUS Medical School, [...]

Scientists are investigating how exercise-triggered stress reshapes the cell’s energy systems, and whether those same mechanisms could eventually help counter metabolic disease. Don’t like the gym? Exercise scientist Ryan Montalvo gets it. He still goes anyway, because the physical strain of exercise often leads to lasting health benefits. Although workouts can feel intimidating, exercise trigger…

Endurance improvements from exercise depend on sustained activation of specific brain neurons after workouts. Exercise does more than build stronger muscles. It also reshapes activity in the brain. In a study published in the Cell Press journal Neuron, scientists report that the long-term boost in endurance from repeated workouts, such as being able to run [...]

Feeding mice with hyperglycemia a high-fat, low-carbohydrate diet lowered their blood sugar and improved their bodies’ response to exercise.

A new study suggests that when blood sugar is elevated, exercise alone may not be enough. Most of us hear the same advice: move more, eat less fat. Exercise can trim body fat, build muscle, and strengthen the heart. It also raises cardiorespiratory fitness, which is often tracked by how well the body can deliver [...]

From skating to curling, the thrilling sports of the Winter Olympics have plenty of science behind them. Follow our coverage here to learn more. When ski mountaineering, or skimo, debuts at the 2026 Winter Olympic Games Milano Cortina in Italy on Thursday, athletes will face off in a brutal test of aerobic capacity. They will schlep their skis up a snowy mountainside that is twice as steep as a t…

In a new study, researchers found even a single workout session could change how the brain works and make it more efficient. The findings suggest exercise could boost brain functions and health. The research was conducted by researchers from the University of Iowa. It is known that exercise like running can improve people’s physical fitness. Scientists have suggested that workouts also bring cogn…

In a new study, researchers found that endurance exercise, such as running, swimming, cross-country skiing, and cycling, could help people age better than resistance exercise, which involves strength training with weights. The researchers at Leipzig University looked at the effects of three types of exercise—endurance training, high-intensity interval training, and resistance training—on the way …

Vicky Stiles, Brad Metcalf, Karen Knapp and Alex Rowlands We don’t yet know whether it’s best to do it all at once, or little and often, but what we do know is that if a woman’s day-to-day activity contains 1–2 minutes of weight-bearing, high-intensity activity, similar to a medium-paced run for pre-menopausal women or a … Continue reading It only takes a minute, girl: women who run for just 1 mi…
