2. Sex Burns Calories
Okay, we can’t claim that sexercise burns as many calories as running or an aerobics class, but getting between the sheets for an hour will burn about 275 calories (for a 150-pound person). Now, don’t expect it to affect the scale that much—you need to burn 3,500 calories to lose a pound. But every little bit helps; and it’s a heck of a lot more fun that sit-ups.
Additionally, when you’re physically active during sex, says Milhausen, your cells, muscles and organs are getting fresh oxygen, which is good for your body.
