If the treadmill in your bedroom looks more like a coat rack than a piece of workout equipment, you're not alone. Many women struggle to commit to and keep up with a regular exercise program.

Often, they've got legitimate reasons for skipping those workouts.

Some women squeeze in exercise by using active workstations, which enable them to move more during the workday. But you may wonder: will this type of multitasking make you less productive on the job?

A study in the May issue of Medicine & Science in Sports & Exercise says it doesn't appear to. The study authors tested the cognitive performance of 58 workers 鈥� 32 young and 26 middle-aged 鈥� who were asked to walk for 50 minutes at a time on an active workstation treadmill. The study authors concluded the walking didn't hinder the workers' ability to effectively complete mental tasks, aside from a slight dip in planning skills during the workout. And they were able to log an average of 4,500 more steps per day during their sessions.

Dog is a woman's best 鈥� workout buddy? Maybe, says a study published online June 9 by BMC Public Health, which found that having a dog appeared to increase physical activity in older adults.

Researchers asked 43 pairs of dog owners and non-owners to wear an activity monitor for a week to track their physical movements. Subjects wore the device three times over the course of one year. They also kept an activity log that included information about themselves and their dog, as well as their daily schedule. As it turns out, the dog owners spent more time walking than those without a dog, and they also took about 2,670 more steps each day. So, if you've been thinking about getting a dog this might give you one more reason to consider a furry friend.

Q. I was an active runner before my hip replacement. Is it okay to return to jogging several times a week?

A. Hip replacements help relieve pain and improve function for people with worn-out hip joints. However, replacement joints also can wear out over time and require what's called a revision surgery. Therefore, activities that may increase stress or wear on the joint are often discouraged.

A canine companion may help older people stay active 鈥� and provide other heartfelt benefits.

If you're among the many millions of dog owners in the United States, you're probably more active than most people without a canine companion at home. But that's just one of the potentially heart-protecting benefits dog owners enjoy, says Dr. Elizabeth Frates, director of wellness programming at Harvard-affiliated Spaulding Rehabilitation Hospital.

"A dog provides love, companionship, and a sense of purpose that propels you to get outside walking every day," says Dr. Frates. Daily exercise is probably the most tangible benefit of dog ownership, she notes. And a new study suggests that the added activity counts toward recommended physical activity goals.

A study of over 60,000 people who were followed for as long as two decades found that people鈥檚 perceptions about their level of activity have a more significant effect on their longevity than their actual fitness.

Physical therapy may be an effective alternative to surgery in relieving joint and back pain.

Exercising may be the last thing you want to do when you have a sore knee or aching back, but it might be the first thing you should do. Physical therapy has long been recommended following surgery. But for some, trying physical therapy before opting for surgery may be the better choice.

"You may be able to spare yourself the expense, pain, and recovery time of surgery," says physical therapist Karen Weber, clinical supervisor at Harvard-affiliated Spaulding Rehabilitation Outpatient Centers in Braintree and Quincy, Mass.

Are you exercising enough to prevent heart disease?

It can help you lose weight; decrease your blood pressure, cholesterol, and blood sugar; and reduce your stress. But wait, there's more: it also lowers your odds of a heart attack or other cardiovascular event and may even extend your life.

This wonder drug isn't a drug at all, of course 鈥� it's exercise. Yet only about half of all American adults do enough physical activity to benefit their health. And exercise is especially vital for people who are at risk for heart disease or already have it.

About 8.5 million Americans have peripheral artery disease, or PAD, in which fatty plaque clogs arteries outside of the heart, most commonly in the legs. The hallmark symptom is calf or thigh pain while walking that goes away when you rest.

The safest, most effective treatment for PAD is supervised exercise training, in which you're monitored while walking on a treadmill. Few people participate, however, partly because of the expense of the regimen. It involves up to 36 sessions of 30 to 60 minutes each over a period of three months.

Studies have linked long periods of sitting with an increase in heart disease and early death.

Odds are you are sitting while you read this. In fact, more than half of an average person's waking hours are spent sitting, according to a study in the Jan. 19, 2015, Annals of Internal Medicine.

All that sitting can cause great damage to your health. "The health risks tied to sitting may not be completely related to the act of sitting itself, but rather that sitting keeps you from doing healthier activity," says Dr. I-Min Lee of Harvard's T.H. Chan School of Public Health.
