The Philadelphia Eagles right tackle -- arguably the best offensive lineman in the entire league -- shared footage of the feat to his social media page Thursday afternoon ... humbly calling it a "quick lil" lift.

While Johnson made the one rep on the trap bar look effortless ... don't be fooled, that is some heavy-ass weight -- the equivalent of one full vending machine!!

Even the NFL was impressed by Johnson's deadlift, the league's official social media page reposted the clip, writing, "That’s that OL strength 💪."

Of course, we shouldn't be too surprised by it all ... the 6-foot-6, 325-pound former Oklahoma Sooners star has been tossing around D-linemen and impressing in the weight room for over a decade now.
