Nearly every day, you can find Juan Bohorquez circling the track.

Walking is his main source of exercise.“I walk and I run one lap which is about 1.6 miles...doctor says I'm okay, 57 years old!”

It's the type of moderate physical activity new research suggests may lower a man's risk of developing heart failure.

“That is the take home message that we want to come away with,” SAYS Dr. Steven J. Keteyian at Henry Ford Hospital in Detroit. “Whether it's for diabetes management, hypertension, preventing heart disease, certain cancers, this is another indication for exercise at a moderate level.”

Heart failure is when the heart is unable to  pump as much blood as the body needs.

Researchers followed more than 30,000 Swedish men for nearly 15 years and found walking and biking 20 minutes each day reduced heart failure risk the most.

It's estimated nearly 6 million Americans suffer from heart failure. The study found both low and very high levels of physical activity could increase heart failure risk. .

Dr. Keteyian says there was a slight uptick in risk for those people that were highly active, heavy exercisers, and did an awful lot of activity throughout the day.

“I think the caution would be is if you engage in that level of exertion make sure your doctor is aware.”

Juan encourages other men to get active

“Definitely get off the couch and run or walk a half hour a day, everyday.”

The study also suggests recent physical activity plays a more important role in lowering heart failure risk than past physical activity.
