Purpose and context
What does the Training Max Calculator do?
A training max is often set below a true maximum to create room for progression and day-to-day readiness. It is a reference, not a required attempt.
Who it supports: Resistance-training users with a suitable actual or estimated 1RM.
Transparent calculation
Formula and calculation method
The entered maximum is multiplied by the percentage as a decimal, with the source of that maximum preserved in the result.
Worked calculation example
A 120 kg estimated 1RM at 90% gives a training max of 108 kg.
The live calculator retains greater internal precision and rounds only when presenting the result.
How to use the Training Max Calculator
- Enter actual or estimated 1RM.
- Choose the programming percentage.
- Identify the source of the 1RM.
- Round to an achievable load.
Understanding your result
The result card identifies the value, unit, method, supporting values and an accuracy notice. Estimated and predicted outputs are labelled so that apparent precision is not mistaken for certainty.
Continue with the 1RM Calculator for a related measurement using its own documented method.
Accuracy, assumptions and limitations
Readiness, equipment and exercise technique can make the calculated load inappropriate on a given day.
Common input and interpretation mistakes
- Hiding that the starting 1RM was estimated.
- Entering 0.9 when the field expects 90 percent.
- Treating training max as a daily target regardless of readiness.

Frequently asked questions about Training Max Calculator
A lower reference can support conservative progression and account for normal performance variability.
Either can be entered, but the source should remain visible because their uncertainty differs.
Round to the nearest achievable plate combination that fits the intended training plan.
No. Programs use different percentages; choose the one specified by the training method.
