| Item | Formula / Rule | Source / Standard |
|---|---|---|
| Epley formula | 1RM = w × (1 + repetitions / 30), suited to estimating from a moderate repetition count. | Epley B 1985, strength testing prediction formulas |
| Brzycki formula | 1RM = w × 36 / (37 − repetitions), which matches measured values closely at low repetition counts. | Brzycki M 1993, strength testing - predicting a one-rep max |
| Estimation error | Beyond about ten repetitions the estimation error grows markedly, so extrapolation is not advised. | NSCA's Essentials of Strength Training and Conditioning, 4th edition |
