Sex counts as cardio! A romp can burn anywhere from 85 to 250 calories, depending on the length of the session (obviously a quickie will be less strenuous than an all-night pleasurefest), says Meston. In fact, cardiologists consider sexual activity comparable to a modest workout on a treadmill, according to a study published in The American Journal of Cardiology.

Not only will your ticker get a workout, but you'll also squeeze in some sculpting: "Your abs and the muscles in your back, butt, and thighs get a good workout as you thrust during sex," says Hutcherson. Looks like you have a pretty good reason to skip spin class on Sunday morning and work up a sweat in bed.
