Creed star Michael B. Jordan is a man of many talents—and obviously a man of exceptional drive, as he revealed in an interview with Amy Robach of Good Morning America on Monday.
"There's a reason you're on the cover of Men's Fitness," said Robach, over some behind-the-scenes video from Jordan's Men's Fitness cover shoot. "What did it take to get to that point?"
"Extreme diet change," Jordan said. "I stripped down my diet completely. Grilled chicken, brown rice, broccoli, a lot of water. I worked out two to three times a day, six days a week. And if you do that consistently for about 10 months, your body will change."
"We'll look just like you?" Robach asked.
"Something like me," Jordan said, either being humble (what a guy!) and/or completely honest that, yeah, he is really freaking jacked.
He also talked about working with Sylvester Stallone, who was much a behind-the-scenes mentor to Jordan as Balboa is to Jordan's character, Adonis Johnson.
"[Stallone] took the pressure off me, not to compete or compare with anything he did 40 years ago," Jordan said. "Physically, I felt the pressure, because they did such a good job back in the day—Carl Weathers and Sly were really cut to a 'T.' So me and my trainer, we really wanted to set the bar pretty high."
And while Jordan worked primarily with trainer Corey Calliet to develop his physical build, he turned to Stallone for his education in on-screen pugilism.
"Stallone knows movie boxing better than anyone else," Jordan said. "[When I] needed to sell a punch, or really 'telegraph this' or 'telegraph that,' he connected the dots for me."
Even his acting was extreme: He waited until filming the movie before running up the famous "Rocky Steps" of the Philadelphia Art Museum. He wanted it to be his "character's first time."
