US-ENTERTAINMENT-PREMIERE-HAIL, CAESAR!Josh Brolin is getting so jacked to play Cable in "Deadpool 2," he even got Dave Bautista to ask, "What the f*ck happened to you?!"

Brolin is giving life to any 49-year-old guys who thought they were past the superhero or supervillain stage. Instead, he's Thanos in the Marvel Cinematic Universe, and co-starring alongside Ryan Reynolds in the "Deadpool" sequel, with more "X-Men" films to come.

Brolin already showed off the uncomfortable face mold process he's endured for Cable, and now he's posting glimpses of his workout. Brolin's latest video is set in the gym, including a lengthy description of his diet and exercise routine:

Quietly, the "Team" is killing it. It takes a small village: @justindlovato at @iambuilt, Jonathon Phillips @hbmaxmuscle, @goldsgym and some discipline. Just saw @davebautista at the gym and he said: "What the f*ck happened to you?!" Haha. Best compliment ever. Totally clean: no sugar, no breads, no pastas, no drugs, none of it. Fish, rice, eggs, veggies, water, one @bulletproof or @cavemancoffeeco in the morning. I'm almost 50. It's a different time: our access along with some big picture discipline results in always surprising milestones. Get on the train. #wedontf*ckaround. #itaintthathard #startslowandlight @weprevail #ryanreynoldsismybitch

Doesn't sound like a fun way to live from here (no sugar, no breads = no thank you) but you can't argue with the results. And you certainly can't argue with a hashtag like #ryanreynoldsismybitch

Here's a shot of "The Goonies" alum in throwback mode, giving us some nostalgia while also showing off his muscled guns (and super hot wife):

"Deadpool 2" is scheduled to open June 1, 2018.
