Cmon twhite you are listing odd examples, you guys performed APRE for a short period of time and it probably shock the system which caused a strength increase etc etc. Your other example, you will always have freaks who were born to bench or sprint etc etc, similar to athletes in the HIT program who can still bench 400lbs or squat 600lbs… Generally speaking 3-6 reps are best at developing strength and 8-12 at developing lean muscle mass.
