In Struct Club, there are two ways to display intensity levels: Effort and Percent. The default setting is to display workout intensity by effort. However, by changing this setting, all new workouts will include percentage-based intensities. There is also a way to change a workout's individual setting. This allows you to change that class's intensity display without affecting any other class.

Option A: Change the Default Setting
From Explore or Library:
Select the Settings gear.

Select "Percent" under "Default Intensity Display."

Option B: Change the Individual Class Setting
From Library:
Select the desired class.

Press the options button.

Select "Percent."

This will apply to that individual class's intensity display without affecting any other class in your Library.
