When most people think of Mark Wahlberg, bulging biceps and chiseled abs probably come to mind.
But the 49-year-old actor, known for his strict fitness regimen, is ditching his ripped physique in order to transform for an upcoming film role.
Wahlberg wrote on Instagram Saturday that he’s “up about 20” pounds in weight — and plans on “going up another 20.”
“Yes it’s for a role,” he added, captioning a video of himself in the gym.
Though Wahlberg did not say which role he’s gaining weight for, the actor revealed during an early April appearance on “Jimmy Kimmel Live!” that he was planning to put on the pounds to play a fighter-turned-priest in an upcoming movie.
“After we do the boxing scenes, I get to put on as much weight as possible over the course of the film,” Wahlberg said. “So I’m challenging myself to put on 30 pounds in the next six weeks.”
And Wahlberg has been committed to the challenge, returning to his Instagram Tuesday with side-by-side photos comparing his body three weeks ago with what he looks like now.
The actor told Kimmel he’s working with a professional to gain weight as healthily as possible.
“Dude, I’ve been on such a regimen for so long, I just want to eat everything in sight,” he said. “I want to go to bakeries. I want to go to Denny’s. I want to get pancakes. I want to get everything that I can possibly get my hands on.”
When asked what his first meal will be when he starts trying to gain weight, Wahlberg suggested a 20-piece chicken nugget meal, hot wings from Kentucky Fried Chicken and a six pack of beer.
Wahlberg isn’t the only celebrity showing off a body transformation. Will Smith, 52, took to Instagram Sunday to share how much he’s let his fitness slide, later teasing an upcoming fitness-focused YouTube series with the working title “Best Shape of My Life.”
“I’m gonna be real wit yall – I’m in the worst shape of my life,” the actor/rapper captioned the pic that showed his chest, stomach and legs. Following the show announcement, Smith shared a more revealing Instagram post, explaining how he gained the extra pounds.
“This is the body that carried me through an entire pandemic and countless days grazing thru the pantry,” he wrote in the caption. “I love this body, but I wanna FEEL better. No more midnight muffins…this is it!”
