The Brzycki Max Weight calculator computes the approximate maximum weight one can lift using the Brzycki formula.
INSTRUCTIONS: Choose units and enter the following:
Max Weight (1RM): The calculator returns the approximate one rep max weight in pounds. However, this can be automatically converted to other mass or weight units (e.g. kilograms) via the pull-down menu.
The Bryzycki formula is:
`1RM = w*(36/(37-r))`
Max Repetition Weight formulas like Bryzycki are intended to provide an estimate on the maximum weight one can lift without having to attempt such a lift. The max one rep weight is estimated based on the total number of reps lifted of a weight less than the weightlifter's established maximum. The motivation is to avoid injuries associated with lifting one's max.
