Incorporating brief spurts of high-intensity physical activity throughout your day can help you move to the next fitness level.

If you're not very active but looking to move more, a new strategy might help you get going. Called high-intensity incidental physical activity, or HIIPA for short, it's a new take on high-intensity interval training (HIIT) — only you might find yourself vigorously pushing a vacuum instead of going for a run.

HIIPA (not to be confused with the HIPAA health care privacy rule) is a term coined in an editorial published online Sept. 3 by the British Journal of Sports Medicine. It borrows from the idea behind HIIT, which is a workout that alternates between high-intensity and low-intensity activity. But instead of performing these high-intensity intervals during exercise, HIIPA encourages otherwise sedentary people to add a few moderately strenuous physical activities during the course of their regular day. Anything that raises your heart rate counts — walking up a flight of stairs instead of taking the elevator, carrying in a load of groceries, or doing some heavy cleaning around the house. The editorial's authors, a team of international experts, say the goal is to perform an activity that gets you a little out of breath.

One in three people ages 65 or older will suffer a fall. It's time to assess your balance and improve it.

Many older adults focus on exercise and diet to stay healthy. But one of the worst offenders to health—poor balance—is often an afterthought. "I see a lot of older adults who are nonchalant about balance," says Liz Moritz, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.

Unfortunately, imbalance is a common cause of falls, which send millions of people in the United States to emergency departments each year with broken hips and head injuries. But there are many things you can do to improve your balance. The strategies below are some of the most effective.

Stroke survivors are typically discharged with a program of exercises meant to help them regain independence. But researchers found that an aerobic training in a stroke rehabilitation program similar to that offered to some heart attack patients helped stroke patients improve their aerobic capacity.

Your core muscles are your body’s foundation, and the plank pose is a great exercise to do to help build core strength—it’s challenging but not complicated. Here’s everything you need to know to plank correctly.

Q. Your article about interval training in the September issue suggests a target heart rate of at least 80% of your maximum heart rate during the high-intensity intervals. But what about people like me who take drugs such as metoprolol, which lowers the heart rate? Should I adjust my target heart rate for exercise?

A. Metoprolol (Lopressor, Toprol) belongs to a class of drugs known as beta blockers. As you mentioned, these drugs reduce your heart rate; they also lower blood pressure. They work by blocking the effects of the hormone epinephrine (also known as adrenaline), causing your heart to beat more slowly and with less force. These drugs are often prescribed for people who have had a heart attack, as well as those with heart failure, atrial fibrillation, or angina.

Cardio not your exercise of choice? Weight training for an hour per week might appeal to you.

Cardio (aerobic) exercise is often touted as the exercise of choice for improving heart health. After all, a body of research supports how it can help lower blood pressure and cholesterol levels, reduce plaque buildup to improve blood flow, and help maintain a healthy weight.

Guidelines recommend that older adults get at least 150 minutes of moderate-intensity aerobic activity per week. But what if you can't do regular cardio because of health reasons or limitations — or you simply don't like cardio exercise?

Even if obesity runs in your family, certain activities may help you lose the weight and keep it off, according to a study published online Aug. 1, 2019, by PLOS Genetics.

Researchers recruited more than 18,000 adults ages 30 to 70 and examined their individual genes and exercise routines. Genetic profiles were created from blood samples that looked for certain gene variants related to obesity. Exercise was defined as at least 30 minutes of activity performed three times a week.

A new study says you might not have to walk far to see benefits.

If you've invested in a fitness tracker, chances are you've heard that you should take 10,000 steps a day for better health. If that sounds daunting, there's good news: a study published online May 29 by JAMA Internal Medicine found that you may able to reap health benefits by taking half that number of steps each day.

Researchers found that in older women, taking as few as 4,400 steps per day was associated with a 41% lower risk of dying during the study period when compared with women who walked 2,500 steps a day or fewer. In addition, it didn't seem to matter if the women took those steps power walking or just moving around the house.

Q. My doctor recently told me I have prediabetes. Is this condition reversible?

A. Yes, it is possible to reverse prediabetes. Prediabetes is a condition that affects millions of Americans. The CDC estimates that as many as one in every three American adults has the condition, which is defined as having blood sugar that is elevated, but not high enough to meet the threshold for diabetes. Left untreated, prediabetes can progress to diabetes, a condition in which your body is not able to absorb glucose for energy properly, causing blood sugar to rise. If it's not managed properly, diabetes can lead to a number of health problems, from heart attack and stroke to blindness, kidney problems, and infections, among others. But making some lifestyle changes can reduce the risk that your prediabetes will develop into diabetes.

Put the focus on friends, family, and fun, instead of food.

It's November, time for Thanksgiving and the start of the holiday season, which is also known as the time of year when healthy habits slide off track and waistbands get tighter.

"The truth is, people do tend to abandon healthy habits during the winter," says Dr. Beth Frates, clinical assistant professor of physical medicine and rehabilitation at Harvard Medical School. Blame the cold weather that keeps you inside and makes you feel sluggish, or the parade of holiday parties. Who wants to stick to a diet or trudge to the gym?
