When you're a comedic actor and you're used to just getting laughs, it's kind of scary to go serious, even for a second.

I started out doing triathlons because they terrified me! I'm a good swimmer, I learned to ride a bike in college, and I hate running. It seemed like something I could never do, so I decided, 'I'm gonna do it.'

Sitcoms are designed for normal people who just want to turn on their TV and get a laugh. It's not high-brow, you don't have to work so hard, and it's meant to be a relatable genre. That's why I love it so much - my fans are from 8 years old to 80 years old, because everybody can relate to what's funny.

Our society is so obsessed with working out to be skinny, and none of that has a purpose. I love that my daughter sees me running because she knows I have a race and that I want to be faster. It becomes much less of a grind when it's that way.
