this really made for lots of inconsistency in peoples programming and lots of questions coming my way from clients.
I then switched to using RIRs and working sets and non working sets. RIR = reps in reserve. as well as intensity techniques where reps are calculated past failure , PF = past failure.
so their program may call for a non working set with an RIR of 4 (in a rep range of 15-20). they are going to take that set 4 reps or so before failure.
then they may have a hard working set where they have a PF of 2 (usually this is equated along side an intensity technique, like an RP.. RP = rest pause).
so lets say a lat pull down has two working sets with a PF of 2 using the RP technique in a 15-20 rep range. they will do that exercise to complete failure, and then using rest pause they will do 2 more reps beyond failure.
however working up to those working sets on that exercise they may have 3 sets with an RIR of 3 (so they went to say 13 reps when their failure point was about 16 reps).
this may sound complicated.. but when its all put down on paper and visualized , my clients have found it way easier then messing with RPE scales. it also allows me to better calculate over all volume and then be selective on our overload and intensity sets.
just my 2 cents on this.
