This video of Konow working out with a friend has been viewed over a million times on Facebook, because Konow is literally working out with her friend, doing squats with her friend draped across her shoulders like a dang feather boa.

This is a really nice workout. First, it's great for building a beautiful butt. Second, it instills trust between friends, unless someone gets dropped, in which case it only builds resentment. But hey, no pain, no gain, right?

Working out is always more fun with a friend.
