Want to lose weight and have fun doing it? According to comedian Jason Sudeikis, it's easy. All you have to do is be in a relationship with Olivia Wilde, spend a bunch of time sexing her up, and the pounds will just melt away.

How's that for an infomercial?

Sudeikis, who's engaged to Wilde, told ELLE's August issue, "The truth is, I’m not getting up an hour earlier and walking on a treadmill. I have the greatest workout partner in the world. And you don’t need a gym membership for that kind of workout."

This backs up something Olivia said late last year, by the way, when she told a crowd she and Jason have sex like "Kenyan marathon runners." (When ELLE asked if that description was apt, Jason replied, "I would say it’s accurate.")

Kinda makes you wonder how they have time to be adorable onstage together. Or plan their wedding. Or go to strip clubs.

Or pretty much do anything at all besides, you know, get bizzy.
