When is it appropriate to focus on aerobic capacity?

@fierceseaman

is there a good metric for aerobic capacity?

By definition, this is VO2Max. WK04/5 provides good estimates, but obviously you can get lab tested.

@fierceseaman

When should I focus on improving aerobic capacity?

It’s a ladder approach from sub-maximal threshold training (endurance/sweet spot/threshold) through lactate clearing (O/U - FTP) to anaerobic (FRC to pMax) with endurance (fat burning) on going throughout. Dozens of great WKO videos (from minutes long to 1hrs 30min/2hrs) to give you the “deep dive” understanding you want. And if that isn’t enough, most of the videos are based on the published research by Dr. Andy Coggan and his fellow researchers (15 such papers have received international recognition).

What is the best way to increased aerobic capacity?

Again, I will refer you to TP/WKO4 videos. As described, it’s the ladder approach (progressive Time-in-Zone) leading to supercompensation. This applies both submaximal and supra maximal threshold (above FTP). For “dialing in” your performance above threshold (including aerobic capacity/VO2Max), you will want to understand Coggan iLevels. (Several videos to watch including Fatigue Resistance, iLevels and Optimized Intervals, among others).
