Formula
Epley formula: 1RM = weight × (1 + reps/30). Brzycki: 1RM = weight × 36 / (37 − reps). Both are estimates, accuracy drops above ~10 reps.
When to Use This Calculator
- Program training around concrete targets instead of guesswork.
- Adjust nutrition and workload as your body weight or performance changes.
- Compare today's numbers to last week/month to spot meaningful trends.
Limitations & Common Mistakes
- Activity formulas assume typical body composition, very muscular or very lean individuals may see large deviations.
- Weight change in the first 1-2 weeks can reflect water and glycogen, not fat loss.
- Always progress load gradually and consult a physician before starting a new training program.
