gosh, you have a lot of assistance work for legs on squat day
Thanks for noticing ;) I think I can get away with the assistance work as I have the weight low and am working on form. I plan on dropping a couple of these exercises and putting in some chin up/pull up work once I buy a bar to put up in the house.
Is that a Body Builder template for 5/3/1?
Only template I've used is just the 5/3/1 percentages on the main lifts, coupled with the fact that assistance work helps (and have chosen my exercises accordingly). So no, I'm not aware of any BB template.
