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."
