These are the One Rep Max Calculators for Calisthenics. With these calculators, you will be able to calculate your one rep max for the strength exercises. Also, you will be able to compute the number of repetitions you should do or the added weight you should put for an specific 1 rep max.


ALL the calculators have 2 options:


=> The first option allows you to compute specific one rep max calculus. This first option has 3 functioning modes possible:

- Mode 1 (default): Compute your maximum one repetition max based on the number of repetitions and the value of added weight.

- Mode 2 (compute repetitions): Compute the number of repetitions you should be able to perform given a specific 1 rep max and an added weight value.

- Mode 3 (compute added weight): Compute the added weight value you should add, given your one repetition max and a defined number of repetitions.


=> The second option will allow you to create a table with all the added weight and repetitions and the correspondent 1RM. Let's see the resulting table and how it works:

One rep max chart example

In the X axis you can find the added weight.

In the Y axis you can find the number of repetitions.

Each cell of the table has a value. This value is the estimated 1 repetition max for a certain weight (X axis) and a number of repetitions (Y axis). For example 4 repetitions with an added weight of 40 kilos would mean a 1RM of 55.9Kg.

The red line is a visual aid. It indicated the values close to our one repetition max to make it easier to identify the number of repetitions and added weight.



The calculators available are the following:
