If you’ve seen Zachary Levi lately it’s obvious that he put on some muscle for his big superhero role in Shazam. So much did he bulk up?

Levi was a guest on the latest episode of Michael Rosenbaum’s podcast and revealed his workout routine that helped him put on 20 pounds in just over a month. Thanks to Collider for the transcript below:

Levi: I’m working out like 5, 6 days a week … Depends. Sometimes we’ll do two-a-days and then more off days, but typically we’ll do an hour-and-fifteen-minute sessions every day.

You’re about 215 now?

Levi: 220. Before I got the role, I was about 200 pounds. I’ve hovered around 200 pounds most of my adult life.

You’ve gained 20 pounds in a month?

Levi: Yeah, about a month and a half.

How many calories a day?

Levi: 3,700 calories, then with a bunch of other supplements like fish oil, Omega-3s …

What are you eating?

Levi: It’s pretty clean and lean.

Does someone make your food?

Levi: Oh yeah, I do meal delivery. It’s part of the job. They [DC / Warner Bros.] have been very good to me when it comes to taking care of this.

Yesterday, Warner Bros. released the official plot synopsis for Shazam and announced that filming is underway in Toronto. The movie is scheduled to be released on April 5, 2019.
