Oh, got it. It's about the equipment.

No, you don't need to be able to calculate VO2 max or use fancy equipment to measure cadence. Pay attention to perceived exertion and use your watch to estimate cadence. ECT will give specific instructions for gearing, but just adjust to your own based on perceived effort. For instance, if he says use your 53x23 gear just go to your largest chainring and smallest cog (or whatever is super hard based on your fitness).
