A standardized warm-up protocol for a VO2 max test includes ~6 minutes easy effort, 6 minutes slightly more effort, a 3-minute threshold gauge, and 2-3 short ~10-15 second efforts towards VO2 max, totaling ~20 minutes.

“I would normally stick to a standardized warmup protocol where you start out maybe for example 6 minutes very easy this can even be walking then I would do or or basically pedaling soft pedaling then I would do six minutes with a little bit more effort... and then I would do a short effort around 3 minutes... and then I would probably also do let's say a couple of short short efforts um that are let's say progressively towards V to Max so let's say one two three maybe two to three efforts that are somewhere between uh 10 15 seconds with with with with with equal rest in between... so you let say you get a total warm up of 20 minutes something like this”
