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.

Complete recovery from total knee replacement surgery can take six to 12 months. Working with a physical therapist to regain strength and mobility, most people can return to normal daily function within three months. It's important to remain active once physical therapy concludes. Lower-impact activities, such as walking, hiking, biking, swimming, golfing, strength training, and aerobic activities, are recommended. High-impact activities, such as running, may shorten the life span of the implant.

An exercise routine that targets muscles in the legs and buttocks can help build the strength and stability that are essential for daily functioning. Lunges are an excellent exercise for this. Older adults can do them safely if they have sufficient leg strength to do the exercise correctly. For those who lack the necessary strength, modified versions can be done until it's possible to gradually work up to doing the full lunge. Once that is mastered, more advanced versions include the side lunge and walking lunge. Holding weights can increase the challenge.
