Wouldn’t it be great if instead of spending 30 minutes on the treadmill or in the swimming pool, you could simply copulate with your partner and shed pounds?
That’s a premise that researchers at the University of Quebec in Montreal decided to check. They gathered 21 couples to volunteer for a month of testing running and sex. The volunteers were hooked to activity monitors as they engaged in their activities.
Alas, sex did not produce the same amount of calorie burn. Men burned 9 calories per minute of running, but only 4 calories per minute of sex. Women burn 7 calories running, and only 3 calories during sex.
Of course some calorie burn is better than none…
