We're not entirely sure what Reese Witherspoon finds so damn funny about running, but we have a few guesses!
Okay, really we only have one guess — and that would be that she's actually wearing clown shoes that honk every time they pound the cement!
It's not realistic, but hey, some people need to do what they gotta just to get through their workout! If Reese needs to run in clown shoes, we can't judge! She's staying healthy!
Ha! She's lookin' fab, though! It's working!
