Myth: For any real benefits, you need to hit the gym for at least an hour or sweat it out several times a week in a fitness class.

Truth: For better health and a reduced risk of death from all causes, any kind of movement is better than little or none.

That means that any effort that gets you moving and breathing - whether it's a twice-weekly heart-pounding kickboxing class or a 30-minute walk - to work has measurable benefits for your brain and body.

That's according to new research published this month in the Journal of the American Heart Association. To arrive at their findings, researchers used data on physical activity and death rates from national surveys of more than 4,800 adults and found that so long as people moved around for at least 30 minutes per day — whether it was through a combination of brisk walking and stair-climbing or a spin class — they enjoyed significant benefits compared against those who didn't exercise at all.

"The key message based on the results," the authors wrote, "is that total physical activity (i.e., of any bout duration) provides important health benefits."
