Markers linked to recovery
Cortisol and testosterone are often reviewed alongside training load. A blood test measures both.
Key points
- Estimates the maximum weight you could lift for a single repetition based on a submaximal set
- Both formulas are most accurate in the 2-10 rep range. Predictions become less reliable above 10 reps
- Epley formula: weight × (1 + reps ÷ 30). Brzycki formula: weight × 36 ÷ (37 − reps)
- The average of both formulas is provided as a balanced estimate. Neither formula is universally more accurate
- An estimate does not require lifting a true maximum. A qualified coach can advise on testing safely
