This easy, stress-relieving exercise may help heal your heart.

If you have a heart attack or undergo stenting, improving your cardiovascular health should be a top priority. A great way to move toward that goal is to enroll in cardiac rehabilitation, a multiweek program of structured exercise paired with lifestyle and nutrition education.

Unfortunately, not all doctors refer their patients to such a program, which is recommended for a number of conditions, including most heart surgeries. Also, for a range of reasons, more than 60% of eligible people choose not to attend cardiac rehab. Sometimes travel and cost issues are barriers. But others worry that the exercise component of the program will be too difficult or tiring. For them, the ancient Chinese practice of tai chi may be a good alternative, according to a small study in the Oct. 11, 2017, Journal of the American Heart Association.

Even if you get enough exercise, you are still at risk for blood clots from too much sitting in front of the TV, according to research presented at the American Heart Association's Scientific Sessions in November 2017.

Prolonged TV viewing has already been associated with heart disease involving blocked arteries, but this is the first study in a Western population to look at blood clots in the veins of the legs, arms, pelvis, and lungs known as venous thromboembolism.

Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline.

Exercise

Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise "dose" of exercise isn't known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.

You needn't spend a cent on fancy equipment to get a good core workout. Many core exercises rely on your body weight alone. But with the help of some simple equipment, you can diversify and ramp up your workouts.

The following items can help you put a new twist on your core exercises. Most of them can already be found around your house or are available at low cost from a sporting goods store.

You might be surprised to learn that what you eat affects your ability to move.

• The nutrients in the food you eat help your body build bone, power muscle, repair and replace tissues, and keep your brain active and your heart pumping.
• Your diet also influences your chances of developing chronic diseases such as type 2 diabetes, heart disease, and osteoporosis — all of which can compromise your well-being and hinder your ability to live an active and independent life.
• Eating the right foods is important, but so are how much you eat and how well you balance the calories you take in with those you burn off. Simply being overweight can make it more difficult to move easily in your day-to-day activities.

Keys to healthy eating

There is no shortage of diet books and healthy eating plans that claim to help you slim down and live a longer and healthier life. But healthy eating is surprisingly simple.

New Year’s resolutions aren’t just for grownups. Taking small steps toward a healthier, more connected life as a family can be fun and help lay the foundation for a lifetime of wellness.

If you believe that regular walking, jogging, or running provides enormous health benefits — as you know we do — there are two good reasons to consider a home treadmill, according to Dr. Aaron Baggish, associate director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. First, exercise outdoors can be challenging and even dangerous in bad weather. Second, if the inconvenience and time required to go to a mall or indoor track keeps you from exercising, being able to do it at home makes it much easier. If you have any balance, heart, or lung problems, make sure your doctor clears you for a home treadmill.

Treadmill shopping

Dr. Baggish recommends avoiding nonmotorized treadmills and opting for a motorized model. "You can get a good starter model for about $1,000, but it's easy to exceed that if you want all the bells and whistles," Dr. Baggish says. Before you make the investment, do a little homework first.

Health guidelines advise all of us to spend at least two-and-a-half hours per week in moderate-intensity activity. For many people, that means walking, which requires no special equipment or training. But even if you can't rack up those 150 minutes, establishing a regular walking routine might extend your life, suggests a study published online Oct. 19, 2017, by the American Journal of Preventive Medicine.

Researchers looked at data on nearly 140,000 adults (average age about 70) who answered questionnaires about their exercise habits over 13 years. People who were inactive were 26% more likely to die during the study period compared with people who did some walking (up to two hours per week) as their only form of activity. And people who walked more — at least two hours per week — lowered their risk even more. The study is observational and doesn't prove that walking kept people alive longer during the study. However, we know that walking is associated with a lower risk for developing high blood pressure, high cholesterol, heart disease, cancer, and diabetes. If you don't want to walk in cold weather, try walking at a mall or an indoor track at a YMCA, or use a home treadmill.

Careful preparation — including a consultation with your doctor — can help you stay safe.

Whether you're a lifelong fitness enthusiast or returning to exercise after a hiatus, training for a triathlon could be a welcome way to focus your workout. These competitions, which combine swimming, bicycling, and running, have grown in popularity in recent years, including among older adults. According to USA Triathlon, the sport's governing body, more than 40% of all members are in the 40-to-59 age group — and some are in their 80s.

However, a recent study documenting the odds of dying during these events may have given pause to some would-be triathletes (see "Death and cardiac arrest in triathletes"). That's unfortunate, because the risk is really, really low, says Dr. Aaron L. Baggish, director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. "These findings shouldn't scare people away from doing triathlons. But the study does identify some issues about these events that are worth understanding," he says.

Friendly competition and other aspects of "gamification" may help people become more active.

If you're one of those people who meet their goal of 10,000 steps on most days, good for you. If you're not — and if exercising feels like a chore — maybe you just need to get your game on.

People who turned their step counts into a competition boosted their daily walking distance by almost a mile, according to a new study. The six-month-long study included 94 families who tracked their daily step counts with a wearable device or a smartphone. Half were randomly chosen for the "gamification" arm of the study, which was designed to encourage collaboration, accountability, and team spirit. These families received small prizes tied to achieving daily and weekly step goals. Just over half of the participants were women, and their average age was 55.
