Captain America has issued the challenge. The 22 Push-Up Challenge, that is.

Chris Evans, along with fellow Hollywood heavyweights Dwayne "The Rock" Johnson and Chris Pratt are taking part in the latest viral challenge.Launched by 22Kill, a military veteran organization, the 22 Push-Up Challenge tasks people to record themselves doing the push-ups, and why they're doing them. The purpose of the challenge? To raise awareness of the high number of veteran suicides committed per day, in the United States. Twenty-Two veterans a day, to be exact. The organization's ultimate goal? To record a total number 22 million push-ups, raising awareness along the way.

Evans, who gets a little interference from his dog, Dodger, posted his video challenge nominating fellow "Avengers" co-stars Jeremy "Renner" (Hawkeye) and Anthony "Mackie" (Falcon) to participate, as well. Kevin Hart, Scott Eastwood (Suicide Squad) and John Krasinski (The Office) have already answered the call of the challenge.
