Leg Press Max Calculator

Formula

The formula to estimate the one-rep max (1RM) for the leg press is:

$\text{1RM} = W \times \left(1 + \frac{R}{30}\right)$

Where:

$\text{1RM}$ is the estimated one-repetition maximum (in pounds)
$W$ is the weight lifted (in pounds)
$R$ is the number of repetitions performed

What is a Leg Press Max?

The leg press max is an estimate of the maximum amount of weight one can lift for a single repetition on the leg press machine. It is a useful measure for strength training and tracking progress. The one-rep max is often used to set training loads for various strength training programs.

Example Calculation

Example:

Weight Lifted: 200 pounds
Number of Repetitions: 10

Step 1: Calculate the one-rep max:

$\text{1RM} = 200 \times \left(1 + \frac{10}{30}\right) = 200 \times 1.33 = 266 \text{ pounds}$
