‘Sons Of Anarchy’ Star Charlie Hunnam Says He Stays In Shape By Having Sex

Like Hunnam, we’re all about having a varied workout routine. Get your sweat on in the gym, the yoga studio, the park—the bedroom. You do you. And Hunnam is on to something by counting the time he spends between the sheets towards his active lifestyle goals: Sex has been shown to have all kinds of brain and body benefits, like burning a few cals and even making you happier at work.

Check out these 14 amazing facts about your orgasm.

Unfortunately, sex isn’t exactly a substitute for your normal gym routine. While you do burn extra cals getting down, sex doesn’t burn enough to replace boot camp. Instead, sex is an awesome supplement to your already kick-ass workout plan. And Hunnam certainly keeps up with his fitness schedule outside the bedroom: “Sweating is how I change my oil every day. I just feel happier, more positive, energized, and disciplined if I work out,” he says. “There’s no reason you can’t be active at 70. I want to run up mountains at that age.” (The Slim, Sexy, Strong Workout DVD is the fast, flexible workout you’ve been waiting for!)
