Taking on a new health regimen can be daunting. Accomplishing smaller tasks that contribute to health may be easier to achieve.

You know what you're supposed to do: exercise daily, ditch junk food, get more sleep, and stay vigilant about every aspect of your health. It's a nonstop commitment that seems like a major undertaking if you've fallen behind. But putting off a healthy lifestyle increases the risk for developing chronic disease and jeopardizes your independence.

Rather than identifying big ways to improve your health, and then procrastinating, focus on small tasks that won't overwhelm you. Try a quick fix once in a while — or all the time if it applies. The more you do, the better you'll feel.

Just a few minutes of rolling can help make your muscles more receptive to stretching and relieve muscle soreness, too.

Working out regularly will help you hold on to your flexibility, mobility, and independence. And using a simple tool may improve this grip on fitness by priming the muscles and making your workouts more effective.

The tool is called a foam roller. It looks like a fat tube or a bolster pillow for a bed. To use it, you slowly roll an area of your body — like your upper back, hips, or calves — back and forth across the top of the roller.

Exercising is one of the best ways to ward off falls. But which type of exercise helps most? A small randomized controlled trial — the gold standard in research — found that tai chi is the winner. The study was published online Sept. 10, 2018, by JAMA Internal Medicine. Researchers took 670 older adults (average age 78) with a self-reported history of falls or mobility problems and divided them randomly into three groups. One group did tai chi only; one group did stretching exercises only; and one group did aerobics, strength training, and balance and flexibility exercises. All of the participants took part in their assigned activities twice a week, for an hour each time. After six months, people in the tai chi group had experienced 58% fewer falls compared with people in the stretching group, and 31% fewer falls compared with people in the group doing several types of exercises. The type of tai chi in the trial was tailored to older adults at risk for falling. But lots of evidence has shown tai chi in general is effective for improving balance. It uses a series of slow, flowing motions and deep breathing. The gradual shifting of weight boosts your strength, flexibility, range of motion, and reflexes.

A French study published Aug. 21, 2018, in The Journal of the American Medical Association suggests that the more steps you take to boost your heart health, the lower your risk for developing dementia. Researchers evaluated health and lifestyle data for more than 6,000 men free of dementia and heart disease men in their 70s to see how they were doing when it came to following seven steps recommended by the American Heart Association: not smoking; controlling weight; getting regular physical activity; eating a healthy diet (that included fish twice a week or more, and fruits and vegetables at least three times per day); and maintaining healthy blood pressure, cholesterol, and blood sugar levels. Researchers also conducted psychological testing on participants at various times. After eight years, it appeared that men who followed five to seven of the healthy habits had the least risk (8%) for developing dementia during the study, compared with men who followed two or fewer habits (they had a 13% risk). The study was observational and doesn't prove that following heart-healthy habits will lower your dementia risk. But many other studies have made similar connections. The takeaway: It's not too late to try to prevent dementia.

Swimming or doing water aerobics can be a good way to keep your heart in good shape.

Looking for an activity to boost your heart health that's easy on your joints and doesn't leave you all sweaty? Swimming might be just the ticket. If you have access to an indoor pool, you can swim or do water aerobics year-round — and throughout much of your life.

"If you were to envision an exercise you could start during childhood and continue well into your later years, swimming has to be near the top of the list," says Dr. Meagan Wasfy, a cardiologist at the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. Swimming also works many different muscles in the arms, legs, and torso. The buoyancy of the water takes the stress off your joints. That can make exercising a little easier if you have arthritis, are overweight, or are recovering from an injury.

The more a middle-aged or older woman walks or does other exercise, the lower her risk of developing heart failure, a new study suggests. Heart failure — which means the heart is too weak or too stiff to pump enough blood through the body — affects some 5.7 million Americans.

Researchers tracked the exercise habits and heart health of more than 137,000 women who were ages 50 to 79 when the study began. After an average follow-up of 14 years, women who got at least some physical activity were 11% less likely to develop heart failure than those who didn't exercise at all — and those with the highest levels of physical activity were 35% less likely to develop heart failure.

Skipping warm-ups and lifting too much can lead to injury.

Exercising is one of the best things you can do for your health, and you deserve an enthusiastic pat on the back for any amount of physical activity you're doing. But if you're performing your exercises the wrong way, you could be hurting, not helping your body.

One of the biggest exercise errors is using improper technique. You risk back injury if you arch your back while doing planks or push-ups, and knee injury if you bend too deeply in a lunge or squat (see "Move of the month").

Are you putting off exercise because you think you need to jump into a rigorous routine? An observational study published Aug. 8, 2018, in the Journal of the American Heart Association suggests that even light physical activity, combined with less time sitting, is associated with signs of better heart and blood vessel health among older adults. Researchers analyzed health information for more than 1,600 people ages 60 to 64 who underwent clinical assessments and wore heart and physical activity monitors for five days. Participants' activity ranged from light intensity — like stretching and golfing — to moderate-to-vigorous activity, like brisk walking, dancing, and lawn mowing. Scientists also looked at participants' blood markers for heart and blood vessel disease, including the inflammation markers C-reactive protein and interleukin-6. The results: compared with being sedentary, people with light to moderate activity levels had more favorable biomarker profiles. The takeaway: lots of research has shown that replacing sedentary time with any amount of physical activity is linked to better health, so don't let high activity goals keep you from getting off the couch.

After heart surgery, patients often enroll in cardiac rehabilitation, a multiweek program of structured exercise paired with lifestyle and nutrition education. A new review suggests that a similar program done prior to surgery, known as "prehabilitation," may help older, frail people to recover better from heart surgery.

The prehab approach goes by the acronym NEW, which stands for nutritional status, exercise capacity, and worry reduction. Targeting those three factors seems to improve people's physical and psychological readiness for undergoing surgery, according to the article, published in the July Canadian Journal of Cardiology.

You have many alternatives for treating and controlling pain.

The opioid epidemic continues to rise in America, and a 2017 report from the National Initiative for the Care of the Elderly suggests the crisis now affects more older adults.

A main reason for the growing addiction to pain medicine is the ease with which it is often prescribed, according to Dr. Robert Jamison, a professor of anesthesia and psychiatry with Harvard-affiliated Brigham and Women's Hospital.
