Re:Mass made simple by Dan John
I haven't done it personally but a lot of people tend to like higher rep squats, Jesse Marunde (R.I.P) was a keen squatter with his catchphrase of 'SQUAT MORE' he was a frequent 20 rep squatter. And I really can't see it being 25 sets of 20 reps! 500 reps??? I think even the most idiotic, sadistic mo-fo's would pass on that. It looks like he's wrote it that way because the weight doesn't change but the reps do I.e 150 kg x 20 x 15 x 10 would be 3 sets at altering rep ranges with the same weight after a short break between each set.
Squat 125kg x 5
OH Press 82kg
