Calcular 1RM para ejercicios de levantamiento de pesas
1-Rep Max Calculator
Estimate your one-repetition maximum using the Epley and Brzycki formulas.
How It Works
- • Epley: 1RM = weight × (1 + reps / 30)
- • Brzycki: 1RM = weight × 36 / (37 − reps)
- • For best accuracy, use a weight you can lift for 1–10 reps with good form.
- • The percentage table helps you pick weights for strength (85–95%) or hypertrophy (65–80%) training.
