Getting in a workout can seem like a daunting task. But what if we told you to live a long life, exercise is more impotant than your cholesterol and blood pressure? That’s the finding from a new comprehensive study that followed 800 men for nearly 50 years.

The only risk factor more likely to lead to an early death among these men was smoking. While the researchers admit they can’t definitively say cigarettes or a lack of exercise caused men to have a shorter lifespan (there are too many variables at play), this study is reason enough to find time to get your sweat on today.
