Speaking with guests Ashton Kutcher and Mila Kunis on Wednesday's episode of his Armchair Expert podcast, Shepard shared that he's gained 24 lbs. over the past year in a quest to become as "huge" as a Marvel superhero.
Kutcher, 43, commented on Shepard's physique, joking that he looks like "He-Man right now."
"In quarantine, I said to [my wife Kristen Bell], 'I've been waiting for 10 years for Marvel to call so that I'd have an excuse to get huge,' " Shepard explained. "And they're not gonna call. That ship sailed. I'm 46, they're not gonna call. So I just have to do it for my own amusement."
Shepard said he "gained about 24 pounds" by working out six days a week, "lifting heavy, protein shakes, going bananas, heavy testosterone injections."

"Mentally, I love it because it makes me far more on fire to be alive," the actor said of his new fitness routine. "I was depressed after CHIPS. I was literally retiring, that was the plan, I'm out… All of a sudden I was on fire to work. ... This is the version I enjoy."
The podcast host said that while he's usually 185 lbs., he now weighs 210 lbs.
"I spent my whole life as a medium boy, and now I'm a big boy and I like it," he said.

Shepard has been documenting some of his gym journey on Instagram.
On Father's Day last month, Shepard shared a photo with some friends and "fellow dads" in the gym for a weight lifting session before holiday activities.
"Father's Day starting with a #dadlift, then on to F1 and too much food," he wrote in the caption accompanying a picture of the group holding weights and kettle bells. "Love you fellow dads, @erickrich@charcurtis@hiryanhansen. Thanks for making parenthood so much fun ❤️"
