Coggan vs Friel Heart Rate Zones

I haven’t checked for a while TBH but is 3 min fairly standard for VO2 max now, what would be the Wattage increase er step? I know some prefer 1-2W every few seconds.

I should have been clearer, Inigo likes 8-10 min steps on lactate tests.

3 mins is fairly standard, although post LT2 step duration is often reduced…

I use 3 on lactate tests because without prior knowledge, the tests would take for ever…and 8 is used for certain retests…

Worth adding that i was skeptical about an absolute value for OBLA…but having run 100s of tests, 4mmol/L is incredibly accurate…
