Go over to Jims website. jimwendler.com. It’s a paid forum he has through his own site. It’s only like 5 bucks though and there’s a ton of training info on there. It’s well worth it.
And sets don’t tell the whole story. Think of total reps. So you’re doing at least 80 total reps of presses (50 reps for BBB and another 30 reps for your dips) 5x10=50 3x10=30. So just to even things out you’d need to do 80 total reps of pulls so maybe 5x10 on chins or row and another 3x10 on some other pulling move. Could be 3x10 on curls to even out flexion at the elbow.
Now say maybe do 100 Total reps of band pull aparts between your 5/3/1 pressing move.
A1 Bench 5/3/1
A2 band pull aparts 100 total reps
B1 Bench BBB
B1 chins 5x10
C1 dips 3x10
C2 curls 3x10.
It’s doable but that could be a lot of volume especially if you are actually pushing the 5/3/1 sets.
I might say drop the BBB and do 5x5 first set last and do the dips for 5 sets of 10 or do the BBB as is and drop the dips and do just some basic pipe work like curls and Tricep Pressdowns super setted at the end.
Just my two cents. Remember you can’t do everything in every workout. Focus your effort in one area (either pushing 5/3/1 or pushing the BBB sets or pushing the assistance work. Trying to do massive volume in all three parts of the workout is just going to most likely bury you.
Also remember you can switch templates and should switch after a few cycles anyway. So hit the BBB stuff for a couple of cycles then push the 5/3/1 sets for two cycles then push the assistance stuff for a couple of cycles (all while doing the bare minimum for the others during those cycles).
Just my two cents. But definitely check out the forum
