A new report in the Journal of the American College of Cardiology reportedly suggests that running too much is very bad for you.

Scientists that studied more than 1,000 healthy joggers and non-joggers over a 12-year period reportedly found that those who jogged at a steady pace for less than two and a half hours a week were least likely to die in this time while those who ran more than four hours a week or did no exercise had the highest death rates, according to BBC News.

This information reportedly remained the same even after researchers accounted for potential confounding factors, such as age, sex, whether the participants had a history of heart disease or diabetes, or whether they smoked and drank alcohol.

“This study shows that you don’t have to run marathons to keep your heart healthy,” stated Maureen Talbot, senior cardiac nurse at the British Heart Foundation.

She added, “Light and moderate jogging was found to be more beneficial than being inactive or undertaking strenuous jogging, possibly adding years to your life. National guidelines recommend we do 150 minutes of moderate-intensity activity a week. It may sound like a lot, but even brisk walking is good exercise. And if you’re bit of a couch potato, this is a good place to start.”

The shocking fact that came from the study was that the most intense runners reportedly ended up with a risk of dying that was similar to that of those who stayed inactive, according to TIME.

The recent study has reportedly suggested that workouts with high intensity that remain brief may be better for the body than long and continuous workouts.

“If you want to do something good for yourself, you don’t have to be extreme. Jogging one to four hours a week for no more than three days a week at a slow to moderate pace is actually achievable. And that’s a positive take-home message,” stated Jacob Marrott, a researcher at the Copenhagen City Heart Study at Frederiskberg Hospital and of the study’s co-authors.
