sure, before Forever i would aim for 5 on 3+ week, 7 on 5+ week, then 3 on 1+. I actually feel better using 5s pro in leaders now and goin for 5 reps on the 1+ week anchors.
I have targets but try to exceed them if feeling good. I dont do 5-3-1 though.
I like to vary the weights up and down. Say Im doing arms I go up 2.5kgs for 3 sets then drop the weight by 10kgs and do volume final 2 sets. Then next session I drop the 2.5kgs and aim for more reps than previously at same weight for 3 sets, then drop 5kgs for final 2 sets same reps.
So when I go more heavy I have a 10kg range between heavy and light. And when go mid range only a 5kg range between sets.
