Estimate your one-rep max (1RM) for any lift based on the weight and reps you can currently perform.
| 1RM (Epley Formula) | |
| 1RM (Brzycki Formula) |
This calculator uses two well-known formulas - Epley and Brzycki - to estimate your one-rep max from a submaximal set. It also shows a percentage breakdown table (50-100% of your estimated 1RM) useful for programming training weights.
One-rep max is the maximum weight you can lift for a single repetition of a given exercise.
