Efron also confessed to ET that while he and Dwayne "The Rock" Johnson look super buff in the Baywatch movie, he's not kept up with the strenuous workouts. "That was pretty intense shape. That involved training two, four, seven, six days a week, 4:30 in the morning -- up everyday," he revealed. "I always maintain health and fitness for life. You know, I love to be able to do anything at all times and be strong, which is just a part of the way I live. You know, cutting water and that's essential to looking like an Olympic swimmer. That was to achieve a specific look it's not functional. I don't need to be that buff to give interviews and stuff."
The actor also recalled walking in high heels for the movie, and said it was one of his hardest stunts. "It's so tough," he admitted. "I don't know how girls do it."
"You're not meant to walk like that," he continued. "You're on your toes, it's really tiring on the legs. I remember at the end of the day, I was just like, I wanted to give up but I couldn't sit down because I would show something. The dress had a slit. I don't know how you girls do it. I give you so much props."
