I am a moron, and jumped on “5/3/1” without reading the book. So I used my 1RM, not my TM, and I also used the reps on week 3 to recalculate my 1RM instead of just adding 10/5lbs. I realised this was wrong when I got the book. And I have already done 3 cycles this way.
Luckily, I have still managed to get some decent progress. My estimated 1RM’s have developed like this:
Deadlift: 130kg -> 160kg
Squat: 115kg -> 140kg
Bench: 77.5kg -> 92.5kg
OHP: 60kg -> 70kg
For my next cycle, I intend to do the program as written. But I am wondering whether I should use 90% of my “new” 1RM’s, or the old ones. I feel like the old ones would be way, way too light, but I am worried that my “new” ones might be too heavy for the slow-but-steady approach that we’re looking for. Would appreciate any input.
