A 2024 study suggested that even five minutes of additional vigorous daily exercise could lower blood pressure.

Wearing a weighted vest can make exercises more challenging and place extra pressure on the bones, which may help maintain bone mass by stimulating the growth of new bone cells. They can be worn while walking, running, or doing body-weight or free-weight exercises.

Chair exercises are a great way to supplement a person's regular workout, or as a replacement when they can't do their usual routine. They also can be used for people returning to exercise after an injury or surgery, or for those with physical limitations. Chair exercises can offer a full-body workout and especially help address two areas people need assistance with as they get older: strength and flexibility. Most chair exercises can be modified to make the movements more or less challenging.

We can learn much from people who continue to live productive lives into their 80s and 90s. Doctors in this demographic have a unique perspective as they have the lessons from their decades of medical practice and their personal experiences dealing with Father Time. Here, two Harvard physicians - Dr. Marshall Wolf, 87, and Dr. Mitchell Rabkin, 94 - share lessons they've learned over the decades from their practice and personal life about how they keep their body and mind strong, healthy, and thriving.

Muscles that support the knee-primarily in the legs and hips-need a certain amount of elasticity to work properly. That "give" allows the joints to move through their range of motion easily. If the muscles are tight, they might cause chronic knee pain. Stretching leg muscles can improve flexibility and reduce knee discomfort. Experts recommend doing dynamic stretching before workouts and static stretching afterward. One should consult a doctor if pain persists after a few weeks.

A 2024 study suggests that reallocating as little as five minutes per day from time spent sitting, standing, or walking to vigorous exercise may help lower blood pressure. Switching out a bigger block of sedentary time for exercise may offer even greater benefit.

Exercising outdoors in winter can offer different health benefits from summer. Cold weather may improve endurance, and the lower temperatures may help transform some white fat, including belly fat, into calorie-burning brown fat. Winter is also an opportunity to take up seasonal sports and activities like fat biking, cross-country skiing, and running or hiking new trails. For safety, exercisers should bundle up, protect their extremities, use sunscreen, and drink enough water.
