Exercise is a weird action in that the action is an intensity, not a severity, which is not as intuitive as others

Check out this post:

> Hello, I am learning the energy system. I don’t know how to set correct intensity for different activities performed by different patients. The average adult male has a maximal work rate of 1200W, according to the documentation in [https://physiology.kitware.com/\_energy\_methodology.html](https://physiology.kitware.com/_energy_methodology.html). Can Pulse calculate the maximal work rate depending on different patients? I think an old male has a less maximal work rate. How to get a maximal work rate corresponding to a specific patient? I check some…

Check out our [Exercise stages](https://gitlab.kitware.com/physiology/engine/-/blob/master/data/human/adult/scenarios/energyenvironment/ExerciseStages.json), where we are going from an intensity of `0.0375`, to `0.075`, to `0.1583`

And our VO2max scenario uses `0.3583`

Again, this intensity is not as linear as our other severity based actions
