The muscular actor also got on Ellen's back.
Milo Ventimiglia can do a push-up just about anywhere and with anyone.
The 39-year-old actor melted hearts on last week's episode of This Is Us, when his character, Jack, started doing push-ups while carrying his 9-year-old son, Randall (Lonnie Chavis), on his back to show that he'd stick with him through anything.

During his appearance on Tuesday's episode of The Ellen DeGeneres Show, Ventimiglia also had the show's host crawl on his back while he did an impressive number of lifts. "I'd love to get on your back while you do a push-up," DeGeneres exclaimed.
Returning the favor, the talk show host then attempted to do a set of push-ups with Ventimiglia on her back, though she didn't manage to do as many reps as the muscular star.
