I have some questions about z6 intervals, (Coggan levels) so here goes!
The time range for these intervals (.5 to 3 min) is fairly large. Are the benefits of a set of 30 second intervals different than a set of 2 min intervals? It seems to me like 30 second intervals might develop 1 minutish power, while the 2 minutes would maybe put a "peak" on vo2max power. Anyone have experience with this?
