Let’s face it, Reacher doesn’t have time for sleep, especially this season. He’s a man on a mission, and he and his team are working really hard to find Teresa and figure out what’s going on with Beck’s business.

Alan Ritchson joins TODAY's Jenna Bush Hager and guest co-host Justin Sylvester to talk about Season 3 of "Reacher,” how he stays in shape for the role and how people are surprised to learn he's different from his on-screen character.
