How to interpret this estimate

Estimate a one-repetition maximum for strength planning. Uses the Epley estimate: weight multiplied by one plus repetitions divided by 30.

When this result is useful

Use it to estimate training loads from a submaximal set without attempting a true one-repetition maximum.

Common limitations

The estimate is most useful for low-to-moderate repetition sets performed with consistent technique. Do not attempt a maximal lift without appropriate training, supervision, and safety equipment.

This calculator uses the selected inputs and the fixed formula behind the tool to produce an estimate. Review the units, assumptions, and result labels before using the output for planning.

Health results are screening or planning estimates only. They do not diagnose health status or replace advice from doctors, dietitians, or qualified healthcare professionals.
