Sex burns a ton of calories – or so says a multitude of women’s magazines that shall not be named. But while getting hot and sweaty in the press-up position can seem like real exertion, how does it compare to fully-clothed workouts?
Unless you go at it like it’s a CrossFit session, not well. A study by the Université du Québec à Montréal found that the average session burns just over 100 calories for men – a modest amount, especially when a light run for half an hour burns around 276.
However, we do at least burn more than women – providing you’re not just laying back and thinking of England, that is. “Men weigh more than women, and because of this, the energy expenditure will be higher,” says study researcher, Antony Karelis. Plus, it turns out we’re usually more physically active during sex.
If you’re keen to burn more naked calories (and you’re morally unscrupulous), take note of another study in the European Heart Journal that found sex with an extramarital partner burns far more calories than regular coupled-up sex. Or, y’know, just get a different kind of training partner and actually go to the gym.
