The** Bench Press Calculator** is a tool used by weightlifters and fitness enthusiasts to estimate their one-rep max (1RM) for the bench press exercise. The one-rep max refers to the maximum amount of weight that a person can lift for a single repetition of an exercise, in this case, the bench press.

**Bench Press Calculator**

The **calculator works** by taking input from the user in the form of their body weight, the number of repetitions they can perform with a certain weight, and the unit of measurement **(kilograms or pounds).** Based on this input, the calculator uses a mathematical formula to estimate the user’s one-rep max for the bench press exercise.

There are several formulas commonly used to estimate the one-rep max, with the Brzycki formula being a popular choice. This formula takes into account the weight lifted, the number of repetitions performed, and a coefficient to estimate the one-rep max.

**Here’s how the Brzycki formula works:**

1RM = Weight × 36 / (37 – Reps)

Where:

- $Weight$ is the weight lifted.
- $Reps$ is the number of repetitions performed.
