When I first started 5/3/1, years ago, I intentionally used a lower deadlift TM then I knew I could pull. I had been pulling sumo-style in my previous, more linear, program. I also had hamstring issues from endurance running training.
I also used a lower TM for the press, based on a 5 rep set I did after benching on the previous program.
For squat: 90% of what I could do for 3 reps. For bench, I flat out used 90% of a slow, grinding 1rm.
Stay with me.
I retested 10 cycles later. My tested 1RM deadlift was 70 pounds higher than my TM. My heaviest single for the press was 40 pounds higher than my TM. I'm not talking about my original TMs. I'm talking about what my TMs were when I retested, and I had gone up the prescribed 5 or 10 pounds every cycle. I never reset either deadlift or press because I'd consistently get 5+ at the 95% weight.
My squat was about equal to my TM, and I had reset it once. My bench? The one I used that lousy, crappy, grunting 1RM for? I reset it three times that first year, and my 1RM a year later had gone up like 10 pounds.
I only stalled on the press when I increased it based on my tested 1RM.
Take from that what you will.
