This is how I planned on doing them as well. I'm doing a Gym Styles rotation this month and planned on starting STS in February. I figured I'd skip the GS workouts one week and do the 1RM's instead. Since GS is Chest and Tris then Back Shoulders and Bis I was just gonna divide the 1RM's up that way, all of the chest and triceps exercises one day, then the ones for back shoulders and biceps on a different day.
