Enter the percentage of one rep max (%) and the relative intensity of the rep (%) into the Calculator. The calculator will evaluate the Relative Intensity.

## Relative Intensity Formula

RI = 1RM / RIR

Variables:

• RI is the Relative Intensity (%)
• 1RM is the percentage of one rep max (%)
• RIR is the relative intensity of the rep (%)

To calculate Relative Intensity, divide the percentage of your one rep max by the percentage intensity of the rep.

## How to Calculate Relative Intensity?

The following steps outline how to calculate the Relative Intensity.

• First, determine the percentage of one rep max (%).
• Next, determine the relative intensity of the rep (%).
• Next, gather the formula from above = RI = %1RM / RIR.
• Finally, calculate the Relative Intensity.
• After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

percentage of one rep max (%) = 50

relative intensity of the rep (%) = 85
