5/3/1 training max calculator

Turn an estimated max into a lower training max for 5/3/1-style percentage work. This is a planning helper, not an official Wendler calculator.

Best for

For lifters reading 5/3/1 material who want a conservative input before building a block.

Set a conservative anchor

Start from an e1RM, then choose the percentage your block should actually use.

90% is the default. Move lower when the input estimate is noisy or you want more runway.

Estimated result

Enter an estimated max.

The result will show your training max and a few percentage anchors from that lower number.

Source-aware

Training max first

5/3/1-style planning starts from a training max rather than a best-day tested max.

This calculator uses the same conservative math as the general training max tool, then frames it for program setup.

For exact 5/3/1 programming, read Jim Wendler's official source material. This page helps calculate an input; it does not reproduce full templates.

Formula and assumptions

  • Training max = estimated 1RM x selected percentage.
  • Default percentage: 90%. Editable range: 85-95%.
  • The official program source overrides this helper when it gives more specific direction.

Use it well

  • Start from an e1RM you trust, not a one-off guess.
  • Use the lower training max as the block anchor.
  • Keep the anchor stable long enough to learn from repeated sessions.
  • Build the routine in Protocol after choosing the program rules from the source.

Keep it honest

Caveats

  • This is not an official 5/3/1 calculator and Protocol is not affiliated with Jim Wendler.
  • Do not use this page as a replacement for the official program source.
  • Use the calculator as a planning note, then enter the routine choices manually in Protocol.
