Well there are a ton of powerlifting routines but as far as reps and sets its about 4 sets (work sets) reps from 5-3-1 depending on how close your getting to the meet. But my rule is when i am off season meaning nothing is on th ehorizon my reps are around 5 to 8, but i will always hit a heavy 5 yr round. But when i start to get ready for specific meet my reps start at 5 and i improve there a smuch as i can. And when i am start to getting some new strength i drop to 3's then 2's. the singles i do i know i can do them but with huge effort. I rarely miss alift in th egym. And basically that is all my lifting, squats are a little different but deadlifts i only pull singles maybe doubles.
Mon chest, shoulder, tris
Tues back
wed off
thurs tri and pulldowns
fri legs.
If your still not clear try going to strength online and go through the archives. that will point you in the righ tdirection. Good luck.
