How many calories you burn while having sex

If hitting the gym for an hour or so isn't exactly your idea of a pleasant way to spend your time, there are a fair few alternatives. 

One of those alternatives happens to be a bit of good ol' coitus. 

 But how good for the figure is the horizontal mumbo anyway?

It turns out that men burn around 101 calories each 25 minutes of sex and woman burn about 69.

It averages to about half of what you'd burn while running a kilometre. 

The paper, which was published by the University of Montreal concluded with:

"Sexual activity may potentially be considered, at times, as a significant exercise."

So go and get some well deserved exercise this evening!
