Whoa buddy, you are definitely overanalyzing the time requirements, but beginners definitely need to bust it in the 85% zone and better. While a beginner can generally handle more reps in that zone than an elite lifter, everybody has different capacities to handle heavier weights. I, personally, cannot do heavy accessory work on DE day after a rough ME day, I prefer to put all my heavier stuff on one day and then do the lower intensity accesiry work DE day.
The best way to find out what you can tolerate is to experiment for yourself.
In the cool tips it said something about how newbies can lift heavier more often cause we don’t have the same neurological efficiency and stuff. DOES that mean if you have 6 months and under of training under your belt…does that mean if your doing an ME day…instead of doing the reccommended 3 lifts at or above 90% of 1RM…you could do like 7-8 lifts at 90%??
…Also is it beneficial to rest 3-5 min. or would 2 min be alright…and then like 3min 30 seconds be the most you should rest??
