Dad bods: We kinda love this trend

At a time when we are presented with pictures of David Beckham's impossible-to-achieve physique, the dad bod comes as a welcome change.

So what's a dad bod you ask?

Not this for one:

For one, it does not always belong to an actual dad. (Move over, David).

According to Mackenzie Pearson, who is credited with coining the expression, dad bods are 'a nice balance between a beer gut and working out'.

Which is to say that if you're a young man who isn't overweight but has a healthy body, you're probably what Pearson is talking about.

You know, like this chap you remember from How I Met Your Mother:

Or.. oh oh... Leonardo Di Caprio (see what they mean by not having to be a dad to have a dad bod?)

Remember he managed to land Gisele Bundchen with that bod so don't lose faith :-p
