Channing Tatum Shares Buff Bod Selfie, Vows to Quit Gaining Weight for Film Roles

Tatum Channing has shed 30 pounds he put on for a movie role – not the first time he's gained weight for a part – and he says enough it enough; "it's too hard" to keep adding and then losing weight.

"On Friday, March 21, the actor, 44, posted a trio of photos of himself on Instagram, showing how his body size has fluctuated throughout the years," People magazine reported. "He said he will no longer take on 'fat roles' because the process is 'too hard on the body.'"

Added the writeup: "Tatum showed off his currently buff physique in the first photo as he posed shirtless in black boxers while admiring his reflection in a window."

"1st photo is today 205," Channing wrote. "2nd photo 235 for a movie called Josephine," he added, referring to an as-yet-unreleased movie. The photo was a black and white mirror selfie in which he sports more around the middle.

"Then went to 3rd photo which is 172 for a movie Roofman," the "She's the Man" star narrated, referring to a film in which he stars opposite Kirsten Dunst, Ben Mendelsohn, and Peter Dinklage, which is expected to be released in the fall.

That selfie showed him looking substantially skinnier than in the previous two photos.

"I'm so grateful for my genetics," the "Magic Mike" star added. "Grateful for my chef/nutritionist/witch. Grateful for my trainer. I couldn't make these big swings in my weight without you guys."

But those "big swings" are over with, the "Hail, Caesar!" actor added. "It's to hard on the body and to hard to take off now.

"But damn," the "Fly Me to the Moon" star went on to say, "when i look at these pics it's just wild what the human body and will can do."
