Efron is playing Kevin Von Erich, the last surviving brother in the family. He was cast in the movie in June 2022, and has used that time to get absolutely jacked.
Zac Efron trained one muscle group per day. He used supersets in his workouts, meaning he didn’t take breaks between exercises so his body burned more calories.
Efron took ice baths routinely to recover from training. He told Men’s Health that ice baths are his “favorite part of the day,” and before them is when he’s “most miserable.”
To achieve the jacked look of a professional wrestler in the ‘70s and ‘80s, Efron needed to bulk up. The actor made many dietary and lifestyle changes in order to do so.
Although Efron still wishes he was vegan for moral reasons, eating foods with protein aided him in his workouts. When he stopped eating vegan food, he intermittently fasted.
Morgan said some of Efron’s staple exercises to train with included overhead squats, pull-ups, back extensions, weighted hanging leg raises, and incline bench presses.
Efron started each day at 11:00 a.m. with bone broth. For his next meal of the day, he combined vegetables with a clean protein, such as chicken, beef, or venison.
Each day, Efron’s last meal was his heaviest. He told Men’s Health they were usually a “good source of meat and [a] healthy carbohydrate, like sweet potatoes or quinoa.”
