Training max vs one-rep max: what is the difference?

A tested one-rep max is the heaviest single you performed under the conditions of that day. An estimated one-rep max uses a recent set to estimate that single.

Both are useful signals, but both can be noisy. Sleep, fatigue, equipment, technique, rep range, and exercise variation can all change the number.

That is why an e1RM should be treated as a planning reference. It can show direction, but it should not automatically become the number that drives every set in a block.

A training max is deliberately lower than the tested or estimated max. It gives the program room when the session is not a perfect peak day.

Example: if your e1RM is 180 kg and you choose a 90% training max, the program anchor becomes 162 kg. Percentage work then comes from that lower number.

That lower number is not pessimistic. It is a way to keep the block trainable long enough to learn from repeated sessions.

Start with the official program rules when you are running a named program. Some programs give specific training-max guidance, reset rules, or progression rules.

If the program does not specify the anchor, choose a conservative percentage and keep it stable long enough to see whether the work matches the intended effort.

Raise the anchor from repeated evidence, not from one unusually good set. Lower it when the same percentages keep missing the intended effort.

Use the public calculators to set the planning numbers, then build the routine in Protocol. Protocol does not pass calculator values into the app automatically.

Once the routine is built, Protocol helps you run the session, log completed or failed work, and keep progression decisions attached to the routine instead of scattered across a spreadsheet.
