What is a One Rep Max?

A one-rep max (1RM) is the maximum amount of weight that a person can lift for one repetition of an exercise. It is a standard measure used to assess the strength of an individual and is commonly used in weight training programs to set appropriate workout intensities.

Example Calculation

Consider an example where:

Using the formula to estimate the One-Rep Max:

\[ 1RM = (200 + 150) \times (1 + 0.033 \times 10) = 350 \times 1.33 \approx 465.50 \text{ lbs} \]

This means that the estimated one-rep max for this example is approximately 465.50 lbs.
