The Lander's Max Weight calculator computes the approximate maximum weight one can lift using the Lander's formula.
INSTRUCTIONS: Choose your preferred units and enter the following:
Max Weight: The calculator returns the approximate 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 Lander's One Rep Max formula is:
`1RM = w/(1.013 - (0.0267123*r))`
Max Repetition Weight formulas like Lander's are intended to provide an estimate on the maximum weight one can lift without having to attempt such a lift. The motivation is to avoid injuries associated with lifting one's max.
This is a derivation of the One-Rep Max calculation
