About 1RM Formulas
Epley Formula: Most accurate for lower rep ranges (1-6 reps). Commonly used in strength training.
Brzycki Formula: More conservative estimates. Better for higher rep ranges (6-12 reps).
Lander Formula: Middle ground between Epley and Brzycki. Good all-around accuracy.
Note: These are estimates. Your actual 1RM may vary based on factors like fatigue, technique, and training experience. Always use a spotter when testing maxes.
