The #22PushupChallenge raises awareness for the 22 veterans a day who commit suicide. It's a serious issue, but the celebrities who have taken up the challenge have had a lot of fun spreading the word.

The challenge is continuing, and you can head here for more information on how to support the cause. Then start doing your own 22 pushups a day and challenge others to follow suit.
