From my earliest bodybuilding days, putting in the work has always meant repetitions. Not just doing reps, but tracking them. At the local weight-lifting club in Graz, I’d write my entire workout on the chalkboard, down to the number of sets and number of reps, and I wouldn’t let myself leave until I’d marked them all off. When I prepared for movies years later, I kept track of the number of times I read the entire script by making tally marks on the front cover, and I didn’t stop reading until I’d memorized every scene.
