Most people know that brisk walking and other movement that gets your heart beating faster is great for your cardiovascular health. But even health-conscious folks often overlook another key fitness recommendation: doing muscle-strengthening exercises at least twice a week.

Not crazy about the idea of going to a gym and hoisting heavy weights? There's no need to do so. You can work your muscles with stretchy bands (called resistance or exercise bands) at home. In fact, if you're out of shape or overweight, a simple resistance band workout can be a good way to ease into exercise, says Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School.

These strategies keep you healthy and safe through your 60s, 70, and 80s.

After age 60, men tend to get thrown together — the so-called 60-and-older group — even though most are quite different in terms of their health.

"While many men are still very fit well into their 60s, 70s, and 80s, others face health challenges and chronic diseases that make daily living difficult," says Dr. Howard LeWine, assistant professor of medicine at Harvard Medical School.

You can still receive benefits from doing less than this recommended amount of aerobic exercise.

Federal guidelines advocate 150 minutes of moderate-intensity aerobic activity per week for optimal health, which breaks down to 30 minutes, five days a week.

Yet the ongoing challenge is how to incorporate these minutes into your daily life. What if you can't find the time? And what happens to your health if you can't hit that number every week?

Even if you've been sedentary for many years, a slow and steady incremental approach can help you reach your workout goals.

Some people count the time since their last workout in hours or days. But you may count yours in years, maybe even decades. You know you need to start exercising to improve or maintain your health. But it's been so long, where do you even start?

The first thing you should know is it's not too late, says Dr. Beth Frates, an assistant professor of physical medicine and rehabilitation at Harvard Medical School and director of wellness programming for the Stroke Research and Recovery Institute at Spaulding Rehabilitation Hospital. Exercise can benefit almost everyone, regardless of age or health status. Provided you get your doctor's okay, you can start now.

What's the secret to living longer? A Harvard study published online April 30, 2018, by Circulation suggests that it may come down to five healthy habits: eating a healthy diet, exercising daily, keeping a healthy body weight, drinking alcohol only in moderation, and not smoking. Researchers combed through information from two large studies that tracked more than 123,000 men and women for about three decades. Scientists estimated that life expectancy for study participants (at age 50) was 79 for women and 75 for men, if they didn't maintain healthy habits. But if they adopted all five habits, life expectancy at age 50 jumped to 93 for women and 87 for men. And following even one healthy habit was associated with a lower risk for dying young. The study is only observational and doesn't prove that healthy habits extend your life. But the findings build on similar research. "It's never too late to make positive lifestyle changes. Even for those who are 70 or older, following a healthy lifestyle such as eating a healthy diet and being physically active can add more years to life," says Dr. Frank Hu, senior author of the study and chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Exercising regularly throughout life is the best way to keep your heart healthy. But starting to exercise even in late middle age may lessen the risk of heart failure, according to a report in the May 15 issue of Circulation. Heart failure, a gradual decline in the heart's ability to pump enough blood to meet the body's needs, affects about 6.5 million people in the United States.

The study involved more than 11,000 people who were part of a long-running project begun in the late 1980s, the Atherosclerosis Risk in Communities Study. Every six years, participants got medical testing and filled out questionnaires about their physical activity.

Aerobic exercise has been linked with reducing symptoms of depression, but resistance training, such as weight lifting and bodyweight exercises like push-ups, can have the same effect.

A meta-analysis published in the June 2018 JAMA Psychiatry examined the effects of resistance training on depression symptoms in 33 clinical trials involving 1,877 people. The researchers found that people who did this type of exercise reported a significant reduction in such symptoms as low mood, loss of interest in activities, and feelings of worthlessness, compared with those who did not exercise.

Do you sometimes feel like the Energizer Bunny with a weak battery? You start out strong, but by midafternoon you're starting to flag.

We all get tired from time to time, but fatigue tends to become more common as we get older. Assuming your doctor has ruled out medical causes for persistent fatigue, there are a few basic steps you can take to feel more energetic day to day.

It might be surprising to learn that parents can help fight childhood obesity by taking good care of themselves. A new study found that when mothers follow five healthy lifestyle habits, their kids are much less likely to become obese.

There's an old saying: "If you want to stay moving, you have to get moving." But for a lot of us, that's easier said than done.

The Department of Health and Human Services (HHS) says we've become a nation of sitters, and our increasingly sedentary lifestyle has become America's primary health crisis, especially for older adults.
