Resistance Training

Resistance training can help fight osteoporosis, especially in menopausal women

Weight-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.

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

That 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.

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

A study from 2025 links having higher amounts of muscle with a more youthful-looking brain age. Scientists analyzed data from more than 1,100 healthy adults around their mid-50s after they underwent full-body MRIs, comparing muscle, fat, and brain age appearances from the scans.Their findings link strength training and controlling visceral fat with improved brain health. The research didn't tease apart why this benefit occurs.

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

That 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.

The exercise sweet spot is shorter than you'd think—and longer workouts aren't generally better

A 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%.

Grip strength predicts death better than blood pressure

In a study covering about 140,000 people across 17 countries, scientists found that for every 5 kilogram drop in adults' grip strength, it raised the risk of death by 16%. Grip strength, the research found, was a stronger predictor of cardiovascular death than systolic blood pressure.

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

Randomized 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.

Watch this how-to video series on how to start strength training

Mayo Clinic put together a collection of videos demonstrating how to get started with strength training, including with exercises like step-ups, abdominal crunches, and more. The Mayo Clinic advises people to try to engage in these exercises working all the major muscles at least twice a week. It also encourages people to inhale and exhale fully between each repetition—inhaling during the less strenuous part of the exercise.

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

The goal with strength training is to stimulate your muscles by straining them a bit, so using any everyday items at home that you can barely lift easily will help you meet that goal. Over time, users can increase the weight they're lifting and their repetitions to provide a greater workout.

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.
