Finding motivation to hit the gym can be tough, but here's another incentive: a bigger paycheck.
A study in the June issue of the Journal of Labor Research shows that employees who exercise regularly earn 9 percent more than employees who don't.
Researcher Vasilios Kosteas of Cleveland State University scored subjects on how they compared to a regular exerciser. The study defined "regular exercise" as working out at least three hours a week.
Kosteas compared similar individuals and found that the ones who worked out earned more money at work.
So, think about that next time you're having trouble going on that run.
