Strengthening the muscles in your midsection may help you stay active and pain-free.

Whether you refer to it as a spare tire, a muffin top, or love handles, having a roll of fat around your waist is pretty common. But even if you're not overweight, a bulging midriff may raise your risk of heart disease.

Despite the many ads that tout "one simple trick" to lose belly fat, there's no getting around it: whittling down your waistline takes a bit of effort. One important step is strengthening your core, which includes the muscles in your abdomen, back, sides, pelvis, and buttocks. However, a strong core is only part of the picture.

Research we're watching

Sitting is sometimes called "the new smoking" because of its detrimental effects on heart health. But some types of sitting may be worse than others, according to a study in the July 2 Journal of the American Heart Association.

Researchers interviewed 3,592 African American adults about their daily activities and followed them for roughly eight years. About one-third watched fewer than two hours of TV a day. Another third watched two to four hours daily, while the remaining third watched more than four hours. People in the latter group had a 49% higher risk of heart attack, stroke, and death than those in the first group. However, there was no difference in heart-related events between people who spent most or all of their day sitting at work and those who rarely or ever sat at work.

Big, round, and soft, exercise balls can put some bounce back into your workouts.

They go by many names: Swiss balls, physio balls, stability balls, or simply exercise balls. No matter what you call them, one of these large, lightweight inflatable balls is one of the most versatile and supportive pieces of equipment you can own.

"Exercise balls are so simple in design and function, yet they can be used for all kinds of home and gym exercises," says Dr. Rachel Lampros, a sports physical therapist with Harvard-affiliated Massachusetts General Hospital. "They can add more benefits to standard exercises like dumbbell curls and sit-ups, and they're one of the best ways to help people with specific limitations. There's a good reason why they are so popular with trainers and physical therapists."

People who track their daily steps generally become more active and are less likely to develop certain health problems, suggests a study published online June 25, 2019, by PLOS Medicine. Researchers examined information on about 1,300 adults (41% men), ages 45 to 75, from two trials. Most were nonsmokers in good health and without cardiovascular disease. The people took an average of 7,500 steps a day and did about 90 minutes a week of moderate-to-vigorous physical activity.

For the trials, half the participants tracked their steps with a pedometer for 12 weeks while the others did not. The pedometer group also received handbooks on walking programs and regular interactions with nurses who offered support and helped them set fitness goals. Some continued to track their daily steps after the trials ended, while others said the experience helped them better gauge how many steps they take each day.

Leg pain when walking that eases with rest may be a sign of peripheral artery disease, which raises risk for other cardiovascular problems. Lifestyle changes — keep walking! — and treatment help.

Protect your independence with gadgets for your home or car.

The simple act of standing up from a sitting position is one of the most important for independence, especially in the bathroom. But the ability to get up sometimes goes south as we age. It could be because of a medical problem or just too much sitting. "When you sit and bend your knee, the gluteal muscles in the buttocks and the quadriceps in the thighs are lengthened. If you sit all the time, the muscles become overstretched and weak," says Clare Safran-Norton, clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women's Hospital.

Exercise can help

If you're able to exercise, try strengthening the "glutes" and quadriceps regularly with exercises you can do around the house.

Adding short bursts of ramped-up exercise to your workout may be good for your waistline as well as your heart health.

For decades, competitive athletes have added brief bouts of strenuous exercise to their workouts to boost their performance. Known as interval training, this practice is now moving into the mainstream, bolstered by emerging evidence of its health benefits for all sorts of people, including those with heart disease.

"There's a growing consensus that interval training helps people lose weight and may have cardiovascular benefits," says cardiologist Dr. Stephen Wiviott, associate professor of medicine at Harvard Medical School. Also known as high-intensity interval training (HIIT), these workouts alternate between periods of high-intensity and lower-intensity activity. You can do intervals during any type of exercise — walking, running, cycling, swimming, or even while doing calisthenics, such as jumping jacks, push-ups, or squats. A longtime distance runner, Dr. Wiviott started doing HIIT workouts at his local CrossFit gym about a year ago. "Even though I was exercising for shorter periods of time, I lost body fat and felt better," he says. His positive experience spurred him to explore the evidence supporting HIIT.

The plank pose is perfect for strengthening your core.

Almost every move you make revolves around your core — from picking up items on the floor, to twisting to see if the coast is clear when driving, to playing with your grandkids.

Your core is made up of several muscle groups (see "To the core"), so keeping each one equally strong and healthy can be a challenge.

The right athletic footwear can protect against injuries.

When one's feet hurt, one hurts all over. That saying, often attributed to the Greek philosopher Socrates, is as true now as it was more than 2,000 years ago.

One of the best ways to prevent age-old foot pain and the soreness that can come with it, like in the knees, hips, and back, is to invest in quality athletic footwear.
