Sorry if this has already been answered. I did a search and got buried under the mountain of results containing “Vo2 Max,” I perused a few threads and didn’t find the answer to my question, which is:
How are Vo2 max sessions supposed to feel?
I ask because I did Bluebell (30sec @120%) today, and I felt it in my legs a bit, but my heart and lungs were just chillin like tempo. When I did Kaiser last month (3min @ 120%), I was nearly gasping by minute three. In other words, it sure seemed like I was at Vo2 max.
Before you say “Bump the intensity up on Bluebell,” lemme say that doing so would toast my legs more than my lungs, whereas Kaiser seemed to really tax my cardio without overtaxing my legs, which would seem to be the point of Vo2 max sessions.
