Chris Pratt, John Krasinski and more have participated.
Chris Pratt is the latest star to participate in a push-up challenge after he was nominated by Hayley Paige.
Pratt posted himself doing the challenge on Instagram.
The “Jurassic World” actor then challenged his “Guardians of the Galaxy” co-star Dave Bautista, actor John Krasinski and friend Caleb Shaw.
Krasinski took to Instagram and accepted Pratt's offer and did the challenge.
The challenge benefits a veterans charity.
For every 25 push-ups Pratt did, Michael Strahan said he would donate a piece of football gear to Merging Vets and Players.
