I’ve noticed that especially VO2 Max workouts I can over-heat even with the Lasko fan. Cooling is clutch especially with that kind of effort indoors.
OP, is there a safe place to do your VO2 max workouts outdoors? PM or not, there seems to be some opinions that you can do VO2 max without power since the goal is to increase HR and breathing rate for a period of time. I just started doing this and it helps me, the RPE is basically the same but I don’t feel like I’m dying when outside for some reason (cooling, moving). Just be sure to place a value on safety and the effectiveness of the workout moving it outside.
