11 fitness-themed mannequin challenges you have to see

Teams, studios, and celebs have used the viral hashtag to show off some serious athleticism.

Search #MannequinChallenge on social media and you'll land on hundreds of videos of folks posing stock-still in the middle of a staged action scene—like the clip of Michelle Obama and the Cleveland Cavaliers frozen mid-conversation at the White House, and the one of Rob Kardashian and Blac Chyna "on pause" in the delivery room. While we're impressed that anyone can remain still so stoically (the challenge is technically one long isometric hold, right?), we're seriously in awe of those who have nailed the viral craze in poses that require impressive strength and balance. Below, some of the most gravity-defying, core-blasting, and stability-testing mannequin challenges we've come across (so far).

Team USA gymnastics

These athletes all deserve gold medals for not falling (let alone blinking) while holding these bendy poses.
