One-Rep Max (1RM) Estimator
Estimate your 1RM for any lift safely using the Brzycki formula.
The One-Rep Max (1RM) is the standard for measuring absolute strength. This formula allows you to estimate your max without the high risk of injury associated with lifting absolute limits.
Knowing your 1RM allows you to structure your workouts scientifically using percentages. Always prioritize proper form and safety over the total weight lifted.
Privacy: Your lifting data and records are never stored, tracked, or shared on our infrastructure.
Terms: 1RM estimates are not medical advice. Lifting heavy weights carries risk; consult a doctor and use a spotter when training.
