Zac Efron’s Muscular Physique Embarrasses Co-Star

Zac Efron gained 15 lbs of muscle to play Kevin Von Erich in the Iron Claw movie. His prep included multiple workouts per day, including old-school bodybuilding, and Olympic lifting on top of the wrestling training. All the cast playing the brothers gained a significant amount of lean weight, but agreed that Zac was in the best shape. Co-Star Jeremy Allen White (The Bear), noticeably got into great shape for the movie, but said he was “embarrassed to stand next to Zac“ because he made him feel so small. Diet obviously plays a crucial part in this too, and Zac has mentioned how the diet for these types of roles is just not sustainable, and he’s looking forward to eating “regular food”. #zacefron #ironclaw #celebritytransformation
