Basic Power Zones vs Enhanced Power Zones? 

Taking a deeper look into power zones in cycling. Coggan Classic Power Levels (Basic) vs Coggan Individual Power levels (enhanced).

The 6 zones in the Coggan Classic Power Levels will do just fine for most people. However, the Coggan Individual levels will provide a better breakdown for the classic Zone 5/V02 Max and Zone 6/Anaerobic Capacity Power.

By looking at the breakdown of the FRC (Functional Reserve Capacity) zones in the Coggan Individual levels , we can better prescribe Anaerobic Capacity intervals of 3 minutes or less with more specific ranges. Note each athlete’s FRC will differ in their timed ranges based on their own individual training data. Click below for more info on this topic:
