Chris Pratt, John Krasinski Honor Fallen Soldiers

Actors Chris Pratt and John Krasinski marked Memorial Day on Monday by taking the "Murph Challenge," then sharing their experience in two online videos.

"We just knocked out a Memorial Day Murph workout," an out-of-breath Pratt said in an Instagram video.

The annual challenge helps raise awareness of the Lt. Michael P. Murphy Memorial Scholarship Foundation. Murphy was as Navy SEAL who is "one of the many in uniform who gave his life for our country," Pratt noted.

"It's days . . . on a day like today, where we just commemorate all those fallen heroes and we say thanks for all you do to make our dreams come true," Pratt said.

The Murph Challenge begins with a 1-mile run, followed by 100 pull-ups, 200 push-ups, 300 air-squats and another 1-mile run.

Here's John's post with all the info we couldn't really get out in my first post since we were both still breathing pretty heavy. Give John a follow if you please. He's an awesome guy. #AndyAndJim #memorialdayweekend #memorialday #murph #murphchallenge #fitness #fitnessmotivation
