Resistance TrainingResistance training is a type of strength and endurance exercise that works muscles against an external force, helping preserve muscle mass and bone density. It includes exercises like squats, push-ups, shoulder presses, and more, to boost the brain and body—whether we're lifting body weight, dumbbells, barbells, or using resistance bands. Exercise physiologists suggest starting the practice early, noting it particularly benefits women in menopause because estrogen reductions can lead to bone density loss, which increases the risk of osteoporosis and bone breaks. Resistance training complements aerobic exercises like swimming or running, which typically keep your heart rate elevated over extended periods, improving cardiovascular health. Adult fitness recommendations include resistance training twice weekly and performing 150 minutes of moderate aerobic exercise—though about 80% of us don't achieve this. When done consistently, resistance training is linked with reduced depression and anxiety and elevated cognition. It improves glucose control, reduces fall risks, and supports grip strength—the amount of force someone can generate with their hand and forearm muscles—a strong predictor of broader health risks, including falling and early death.Explore Resistance Training

Healthy adults should perform 'progressive resistance training'That's the recommendation in March 2026 from the American College of Sports Medicine. They reviewed existing studies on the topic and concluded that resistance training with progressively more weight and repetitions improves muscle strength, size, power, endurance, gait speed, balance, and more. National Library of Medicine Resistance training is linked to better memory and cognitive function in older adultsRandomized control trials looking at structural neuroimaging and exercise suggest that resistance training in older adults induces structural brain changes that could reduce the risk of Alzheimer's Disease or mitigate its progression. The benefits have been documented when performed at least twice per week for at least six months. National Library of Medicine Resistance training can help fight osteoporosis, especially in menopausal womenWeight-bearing training that pulls on bones, joints, and muscles can strengthen bone health. Movements like squats, rows, shoulder and chest presses, and push-ups can be started at any age (if you don't already have advanced bone loss), though ideally they should be started earlier—in one's teens or young adulthood—to stave off bone density losses that begin in your 30s. FoundMyFitness Microbial research suggests shifts in diverse populations may help an invasive species establish itselfIn 1958, English ecologist Charles Elton suggested that diverse ecosystems should be more resistant to invasive species because gaining a foothold would be more challenging when resources are more thinly spread. However, in lab-grown microbial ecosystems with greater biodiversity, population volatility opened more ecological roles that invasive species could easily fill. Quanta Magazine The exercise sweet spot is shorter than you'd think—and longer workouts aren't generally betterA meta-analysis concluded that resistance training for about 60 minutes per week provided the best health benefit—decreasing the likelihood of death for individuals within a specific timeframe around 27%. National Library of Medicine Adults need two days of muscle strengthening activity weekly—yet most of us aren't doing thatThat recommendation—muscle-strengthening activities on two or more days a week working all major muscle groups—is in addition to 150 minutes weekly of moderate-intensity physical activity. Those resistance and aerobic training numbers from the US government are echoed by other medical groups. But nearly 80% of adults aren't checking the box on those goals. This failure is linked to about $117B in annual health costs and some 10% of premature mortality. US Department of Health and Human Services - Office of Disease Prevention and Health Promotion Adults may lose roughly 3% of their muscle mass each decade after 30That muscle loss, formally referred to as sarcopenia [saar-ko-pee-nee-uh], averages 3% to 5%, depending on physical activity. These losses can progress with age, but resistance training helps combat some of this natural degradation. US Department of Health and Humans Services - Office on Women's Health 'Menobelly' is real, with more fat stored around the abdomen as estrogen levels dropThe way fat is carried in the body shifts with menopause, with those pounds increasingly settling around the abdomen instead of the hips and thighs. Exacerbating this phenomenon, muscle mass also begins to decline, so calories stick around longer than usual. Resistance training, including push-ups and planks, alongside a heavier protein diet can help. Harvard Medical School People with schizophrenia have triple the risk of developing diabetesIt remains contentious if something inherent about the disease or antipsychotics' side effects (weight gain) are mostly to blame. Some newly diagnosed schizophrenia patients already have insulin resistance, raising questions about if patients' brains are getting enough energy from glucose, and if dietary changes—like a high-fat, low-carbohydrate, moderate-protein diet—may help alleviate symptoms. Psychology Today The Stamp Act's real purpose was protecting colonists from Native AmericansThe troops the act funded weren't left in America to guard against France, but to manage the aftermath of Pontiac's Rebellion and keep the peace between colonists and Indigenous nations. Some historians argue this means Native American resistance to British expansion indirectly triggered the tax that sparked the Revolution. National Endowment for the Humanities What do people do once GLP-1 medications succeed at weight loss?The drugs have been adopted by 1 in 8 Americans, with many achieving their prescribed weight loss. They now face the question of how to keep the weight off, the key issue with any weight loss program that researchers have known about for decades. Each case is unique. Some folks continue to use GLP-1s like Ozempic in minuscule doses, while others taper them off over time. The Conversation Review an historical exploration of Charles Darwin's expeditionsDarwin spent more than half of the Beagle expedition in Patagonia, discovering large mammal fossils, including extinct sloths. He journaled about the Argentine genocide of Indigenous peoples in the regions while making findings that would contribute to his theory of evolution. The Guardian The fintech industry was worth roughly $340B as of 2025Venture capitalists have been bullish on the industry’s future in recent years, too. Some estimate that global investment in fintech increased by 12,000% between 2008 and 2020. Going VC The Navier-Stokes equations include the fluid version of Newton's second lawThe first equation is the fluid version of the conservation of mass, which prevents incompressible fluids from gaining or losing matter. The second equation replaces acceleration and inertia, which is resistance to acceleration, with fluid pressure and viscosity. Medium The world rapidly decolonized after World War II After WWII, weakened European powers faced mounting resistance from colonized peoples. Between 1945 and 1980, dozens of nations across Africa, Asia, and the Middle East gained independence. CFR Education from the Council on Foreign Relations Optimal human functioning requires movementThere 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. Frontiers Nearly every major automaker now offers a hands-free driving systemThe capabilities of these systems range from automatic lane changes via eye-tracking to an assistant that reminds you to check your blind spot before changing lanes yourself. Most systems still require the driver to remain alert and be prepared to take over. Car and Driver Pros and cons of minimum wageThe federal minimum wage hasn’t been raised since 2009. Over the past decade or so, proponents of significantly raising the minimum wage have argued that doing so could reduce reliance on government financial assistance programs and increase consumer spending. But opponents say higher labor costs could lead to job cuts. SoFi
