I don't know what my true maxes were before starting 5/3/1 but I would venture to say squat and pull was around 475-485 and bench paused around 325. Lets just say before 5/3/1 I had a somewhat bad feeling when I would force myself to go above 405 on squats/deads. By the time of the meet working up to 5 plates each side was no big deal even though it didn't show quite as much as I would have liked it to in the meet.
Assistance for squats I sometimes did on my heavy pull day and assitance for deads I did on my squat day. I know that sounds funny but I was fresher as I have mentioned in an earlier post. A typical squat day I would squat heavy and then perform heavy lockouts or maybe some speed bulls against the band. I really like doing 4-8 sets of 3 on deads against the band with 30 seconds rest.
I feel that for my upper body pressing day I would follow up bench with some chain resisted bench or incline d-bell, nothing fancy programming wise. I actually would do chest/back on the same day. After I focused on my heavy benches I would normally superset chest/back for at least 2 more exercise of each. I did a decent amount of 1-2 board pressing but not paused because I have had elbow problems. So a typical upper body day might look like this...
flat barbell benchpress for reps prescribed for the day
Superset #1 weighted pullups 4x8 with 2 board pressing 4x5
superset #2 plate bent row 3x8 with incline d-bell benchpress (<45 deg angle) 3x6
superset #3 weighted dips 3x8 with d-bell rear delt flies 3x10
I know many would bash on doing supersets with a powerlifting routine but it allowed me to still focus on some aesthetics while making my workout shorter. Any other questions or routine anyformation I am happy to give.
