VO2 max is a remarkable integrator of work, reflecting an astronomical volume of past effort.

“V2 Max is probably a remarkable integrator of work so it is not a biomarker that changes quickly and easily to the magnitudes required to do this right um you know you're not going to take your V2 Max from low to Elite in a year um you can do it I would argue you absolutely can do it but it's not going to happen in a year and therefore when it happens it's going to reflect an astronomical volume of work that has been done and the benefits of that work are what are being captured in the V2 Max number”
