Where Is The Intensity Adjustment?
Open the menu inside the workout and select the settings tab. At the top of this menu, you will find the intensity adjustment.
The MASTER Switch
The switch is flipped to "Master" by default. When on "Master" the app adjusts intensity in a traditional way, applying a percentage adjustment to all of your workout targets equally.
The INDIVIDUAL Switch
When the switch is flipped to "Individual" you now have the option to apply intensity changes to each of your 4DP metrics individually for the selected workout.
