The Brzycki Equation

The Brzycki Equation is a formula used by fitness professionals to estimate the maximum amount of weight a person can lift for one repetition, known as their one-rep max (1RM), based on how many repetitions they can perform with a lighter weight. It helps determine personal strength capacity without risking injury from attempting an actual max lift. The equation involves dividing the weight lifted by a factor that accounts for the number of reps completed, providing a practical way to assess strength and plan training safely.
