Clarification

Some have asked about moving your VO2max. Technically you cannot move your VO2max. It is determined solely by genetics. The purpose of the VO2max workouts is to be able to run at your VO2max for long periods of time. What you are moving is your current ability to transport oxygen to your heart. Let's say my VO2max is 100. However, today, my current ability to transport oxygen to my heart is 70. What the VO2max workouts do is allow me to achieve my ceiling (my VO2max). However, everyone's ceiling is different. If my ceiling is 100, Lance Armstrong's drug-free ceiling is 300. With drugs, it's probably 350. I kid. I kid.
