Sitting has been described as the “new smoking.” While that may sound discouraging if you’re always driving long distances or sitting in an office chair for hours on end, there is something you can do about it. Moderate exercising like walking the dog or riding a bike for just an hour a day could alleviate or even eliminate the dangers caused by sitting all day. And if you’re worried about a full hour, benefits still come from spreading those 60 minutes out throughout the day.

Depression isn’t confined to adulthood. One recent survey showed that nearly 11% of adolescents ages 12-17 were depressed. But one treatment commonly used to combat depression in adults may also be beneficial for adolescents who suffer from depression. According to a recent meta-analysis collected from rigorously evaluated studies, adolescents may experience improvement in their depression symptoms if they incorporate exercise into their treatment.

For people suffering from knee osteoarthritis, one long-standing solution to knee pain was the use of “unloading” shoes. These shoes use stiffer soles and slightly tilted insoles that help to reposition the foot and ‘unload,’ or decrease, the pain on the knee. But a new study revealed that these shoes might not be any better than good walking shoes at relieving pain from knee osteoarthritis.

How many times your heart beats per minute when you’re resting — also known as your resting heart rate (RHR) — can provide important clues to your current overall health and even predict possible future health problems.

Exercise: It does so much more than burn calories

Elizabeth Pegg Frates, MD

You’ve probably heard that if you want to lose weight, it’s as simple as “eat less, exercise more.” A recent study suggests that a lot of exercise doesn’t always translate into a lot of extra calories burned. But even if you never lose a single pound with exercise, it has so many other benefits for your body and mind that it’s always worth it to be active. Give it a try today!

The health benefits of dancing are as beneficial as other forms of exercise, and are accessible to almost everyone regardless of age or range of mobility. Moreover, by incorporating music, dance may have benefits beyond those of exercise alone. Music stimulates the brain’s reward centers, while dance activates its sensory and motor circuits. Dancing has improved balance, gait, and quality of life in people with Parkinson’s disease and related movement disorders.

The benefits of regular exercise are well understood, but some forms of exercise carry a higher risk of injury than others. A new study of female runners suggests that an individual’s running style may play a role in susceptibility to injury, but it also raises questions about technique that warrant further study.

The connection between your brain and your body is a two-way street. This means that how you feel affects how you move — and that the opposite is true, too. Here, we’ve assembled plenty of evidence that movement — whether it’s aerobic exercise in a gym or a simple meditative walk — is incredibly effective not only for boosting your mood, but for reducing symptoms of many common mental disorders, too.

People who exercise more also tend to drink more (alcohol)

A recent study that tracked healthy volunteers’ exercise and drinking habits found that they tended to drink more on days when they exercised more. But this study might have had drastically different results if conducted with different groups. For example, what results might we see if the volunteers were sedentary people looking to exercise more — or people with unhealthy drinking patterns who were working to cut back?
