This assessment provides statistical probability and mathematical interpretation based on validated clinical equations. It is not a diagnostic tool.
Estimate the maximum weight you can lift for a single repetition based on sub-maximal performance.
The Brzycki formula, developed in 1993, is one of the most widely cited equations in exercise physiology for predicting 1RM when a true maximal lift is unsafe or impractical.
The more reps you do, the less accurate the prediction becomes. For the best accuracy, try to perform a set of 3 to 5 reps with good form rather than a high-rep set (10+).
