How Are VO2 Max Sessions Supposed to Feel?

@Teuthis

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.

As posted by @bbarrera in a relevant thread:

Quads burn during build phase

here are levels 4-7 of that table: [15%20AM] As mentioned above, I’ve spent a lot of time doing Level 4 / LT at longer and longer intervals, and mentally am now pretty good at ignoring the muscle burn.

As per the description: VO2max – “…may not be achieved due to slowness of hear rate response…”; Anaerobic – “Heart generally not a useful guide…” It may just be that your heart requires longer intervals to respond and reach >90% HR.
