this is my approach as i continue to punch the clock on these workouts- it is always reps at the top and bottom of the minute (i.e. every 30 seconds, but always ensuring compliance withe the strong first stop signs)
the key seems to be waviness (inside the workout) and practice- all the while managing fatigue- i.e. never getting actually "tired"
i try to establish for each workout specific goals- so yesterday, looking back at the last few weeks of training, i wanted to get a lot of reps in but also back off a bit
so the pattern was-
53 for 1, 53 for 2, 53 for 3, 62 for 2, 62 for 3- then the cherry on top of each of these "stacks" was either 1, 2 or 3 reps w/ the 70
so... lots of reps, minimal fatigue- total of 60 minutes- so i got to practice the 70 (motor unit recruitment for strength) and practice lighter weights (motor unit recruitment for speed/power/explosiveness)
all this practice- "if you want to press a lot, you have to press a lot"- works for both maximum strength AND endurance- motor unit recruitment seems very high- so the skills and quality of the movement continues to improve- and i can imagine that i'm building tons of mitochondria
and the variance between each workout keeps things very fresh and interesting- but the key seems to be always working on the next set feeling like you are NOT accumulating any fatigue
