A small, short-term 2026 study suggests that people who schedule their exercise to align with their chronotype—the body’s natural sleep and wake cycle—may lower their heart risk factors more than those who exercise at times that don’t align with their chronotype.

Beyond familiar kettlebell exercises such as kettlebell swings, many lesser-known kettlebell moves can create a full-body workout. Examples include around-the-world passes, bottoms-up kettlebell carries, and kettlebell deadlifts.

Men tend to lose as much as 3% to 5% of their muscle mass per decade after age 30, and the muscle-building hormone testosterone gradually declines after age 40. This makes it harder for men to build and maintain muscle as they age. One solution is a well-designed weight training program. Workouts should focus on all major muscles, but men should pay extra attention to leg muscles, which they rely on more for everyday movements as they age.

Achilles tendons can be injured in several ways. Overuse can irritate and inflame the tendon (tendinitis). Abrupt movements that stretch the tendon in the wrong way can tear the tendon (rupture). Nonsurgical treatment often is effective. Some cases may require surgery.

After an ablation procedure for atrial fibrillation, getting at least 90 minutes of moderate exercise per week may reduce a person's risk of an afib recurrence, according to a 2026 study.

Virtual cardiac rehabilitation offers heart-related education and supervised exercise classes that people can access at home using a computer, tablet, or smartphone. This growing trend may help make cardiac rehab more convenient and accessible.

It's easy to blame running when a person who runs regularly develops arthritis. But that blame may be misguided. Here's a look at the latest research on the topic.

A large 2026 study estimated that adding just five minutes a day of moderate to vigorous activity might prevent up to 10% of deaths during an eight-year period. Sitting for 30 minutes or less might prevent up to 7% of deaths.

An analysis of 217 trials found that lower-impact aerobic exercise (walking, cycling, and swimming) is most effective for easing knee osteoarthritis pain and improving function. Other exercise types, such as flexibility, mind-body, neuromotor, and strengthening, also offer benefits.

Among 12 physical therapy approaches for knee osteoarthritis compared in a 2025 study, three stood out. Knee braces, followed by hydrotherapy (exercise in water) and exercise (strength training and aerobics), were best for reducing pain and stiffness and improving physical function.
