If you're using sex as your only viable form of exercise, you might want to come up with plan B.

A new study out of Canada has solved the age old question of whether or not sex can be considered exercise. The answer is, not really. At best, it can be considered a very minor form, like laughing or signing karaoke.

The study coming out of the University of Montreal recently ran the numbers on the calories burned during sex.

What they found is the typical man burns 4.2 calories per minute during sex, a woman around 3.1. That by the way is the same amount as you'd burn walking or ballroom dancing.

So, let's say you have the staying power of two minutes, (hopefully not, but for the sake of discussion let's say you do) that means a man would burn 8.4 calories and a woman would burn 6.2. If that is indeed the case, congratulations, if you're a man you have just burned off about two-and-a-half M&M's. And ladies, you've melted off two.

Even if you have the kind of stamina that only a professional porn star seems to posses, and have the ability to last for an hour, a man would only end up burning 252 calories, while a woman would burn just 186.

So if you need to drop a little weight, don't just rely on sex. You should probably get to know a piece of gym equipment too.

I wonder how many calories a person can burn having sex while using a treadmill? Hmmm? Sounds like it might be time for a new study!
