From the looks of recent photos and gym videos the actor has boastfully be posting to Instagram, he's even more jacked than co-star Ryan Reynolds.
Reynolds suggested his good standing with the swole patrol is now in jeopardy now that he's facing off with Brolin for the Deadpool sequel.
"I've spent this last week on the business end of many Josh Brolin punches—both verbal and physical and literal, and it's going to be pretty fantastic," Reynolds told Fandango.
"He's going to be epic. He's going to be an epic Cable."
Here's a side-by-side for anyone who's somehow still not convinced.
How Brolin got there should be to no surprise: intense gym workouts and plenty of protein and brown rice.
