I may just need to reasses my "Max" to start.
Otherwise its gonig to take 4 months to 5 rep what I 3 rep now.
Maybe I work backwards, with a bit of conservatism.
Wendler says take your best 1RM lately, subtract 10%, and go from there.
Or, you can take your 5RM, use the formula to create a predicted 1RM, and use that. That method is at least internally consistent, it will have you doing about your 5RM on your first 5+ day, and just under your predicted 1RM on 1+ day, so you'll find out quick.
You can also go up by larger increments, 7.5# for bench, 15# for squat, etc., which I did on rows and bench when i was getting crazy results like 11/7/5 for, respectively, 5+, 3+ and 1+ days.
But of course everybody will tell you that if you do that you are going to stall sooner, or rather, stall harder. I really have no idea what to expect there. I have not stalled on deadlift yet, paused for one cycle on squat, and was rocketing forward with bench before I injured myself. Insufficient data for meaningful response.
