Estimate the maximum weight you can lift for a single repetition based on your submaximal performance.
Your one rep max (1RM) is the maximum amount of weight you can lift for a single repetition with proper form. It's a key metric in strength training used to programme training loads and track progress over time.
This calculator uses the Brzycki formula, one of the most widely used equations for estimating 1RM from submaximal lifts. The estimate is most accurate when using a rep range of 1-10. For heavier programming decisions, always consult with a qualified strength coach or personal trainer.
