That is what I was trying to understand as well. 75% of my max for 15? Am I rest pausing it??? lol
That is what I have been trying to tell you guys.
I rest about 60-90 sec. between sets. (Note: I do 15 - 18 exercises up to 3 sets for week 5-6) also take in consideration I can no longer do compound lifts)
you can increase or decrease the rest between sets.
you have to watch the one rep calculators.
I have yet to find a calculator for HST that is accurate to reality.
This is why I say 75% is about 3-4 reps left in the tank.
this is why it also takes a little time to find your rep %.
IE: last workout I was benching 225 for 10 reps at the end. start with 175 and see how it goes and make adjustments from there.
also with the smaller muscle groups you will usually have to increase reps over the 15, 10 or 5 as you progress. adding 5lbs sometimes makes you go from 15 reps to 7. if this makes sense?
adjust as you go. most of us have a general idea how much weight and how many reps we can get with certain lifts.
if you hit 25 reps do it and adjust it, if you hit 9 reps and say o crap just adjust it. (when you are this far off it may take the first week to get it were it needs to be for the particular %.)
Don't blow a nut across the gym on the first day.
If someone has a calculator that estimates Percentages of one rep max to a number of reps up to 15 that is accurate I would love to see it. this would be a great help.
