The study, led by New York University Langone Health researchers who looked at data from more than 6,000 Fitbit users who were part of the All of Us Research Program, found that an extra hour a week of increased activity reduced risk of developing the irregular heartbeat by 11%.

Engaging in moderate-to-vigorous exercise, which can range from taking a brisk walk or cleaning the house to swimming or jogging, at least for 2.5 hours per week may keep your heart healthy, and help reduce the risk of irregular heartbeat (arrhythmia ...

Study participants who averaged between 2.5 and 5 hours of physical activity a week—which is the minimum amount recommended by the American Heart Association—had a 60 percent lower risk of developing atrial fibrillation. Those who averaged more than 5 hours a week of activity had a 65 percent reduction.

New research indicates that 1 hour of moderate exercise per week can help prevent atrial fibrillation (AFib). While a small amount of exercise reduced AFib risk, study participants who exercised more reaped even greater benefits.
