Pareto Front

    I have a weightlifting spreadsheet with weight on the vertical axis and reps on the horizontal axis. The value of each cell is the estimated 1 rep max if I accomplish that lift. In theory if my e1RM is 100kg then I can lift any permutation of (weight,reps) that have the same e1RM. This is akin to knowing Pareto Frontier of my current strength.

    I use conditional formatting to color cells according to the probability that I can lift them—if I lifted 50kg for 10 reps then I can definitely do 50kg for 9 reps, so that cell is green. But if e1RM(50,10) > e1RM(40,15) then I can probably do that too so it's light green. The visualization naturally becomes Pareto-like.

    If I'm feeling strong I can aim for higher weight, lower reps. Or if I'm feeling weak I can close out a (weight, reps) that's below my current e1RM but I haven't accomplished yet. The end result is that I'm always "accomplishing" some sort of PR no matter how I feel.

    I call this e1RM Bingo.

      Could you please share this spreadsheet? I would really love to have my own version of this.

        Just copy-paste that description to Claude and have it create the spreadsheet.

          The last time I tried this was back with Opus 4.6, and it was ok. I tried it with Fable 5 High just now and I was very impressed with the output. It took 7 minutes and one turn.

          I'm not one to believe in all the one-shot hype, but this was pretty good.
