So, I use this as an excuse to buy beautiful Moleskine, Leuchtturm, and MUJI notebooks and coloured pens, and I stash them in my gym bag. Each day before class, I open the app and copy the workout into my notebook. I do any necessary calculations, which is the basis of weightlifting training. I lift based on percentages of a “1 rep max” (1RM), which has been established prior, and often these percentages increase over the course of a training session.
For example, last week, I did 6 sets of power clean and jerks. Each set had decreasing reps (3-3-2-2-1-1) at increasing percentages (60-80%). I calculated and wrote out those specific weights in advance, so I could spend more time warming up and preparing mentally.
