We’ve all been there: upset and caught in a loop of despair. You feel like this photo of Bette Davis. You drop on the bed and obsess. Or worse, go on a binge—eating, drinking. The best thing to clear your head? Go work out. Now, it won’t be easy at first. The law of physics, after all, says things at rest stay at rest. You gotta get up the will power to get moving. But once you do, it gets easier. Things in motion stay in motion! After the work out, you won’t feel like Bette looks.
