Apple Watch VO2 Max explained: How it could save your life (and how to improve it)

Tshaka Armstrong tests VO2 Max

“VO2 Max.” It sounds like an 80’s “teen meets machine,” cartoon superhero. Like, some kid named Max says some catchphrase, “VO2 Max..ax…ax…ax,” and his motorcycle transforms, becoming a part of some super suit he wears to dispatch some corny cadre of super villains. 

Well, that description IS somewhat accurate. Having a solid VO2 Max may make you feel like you are in fact, superhuman. And Apple thought enough of Max and his VO2-ness to include it as a standout metric in Apple Health, even notifying you if you have “low cardio,” meaning a low VO2 Max number, like me.
