VO2 Max & Metabolic Health

The single most predictive fitness metric

VO2 Max & Metabolic Health

About this course

VO2 max is the single strongest predictor of all-cause mortality we can measurably improve. Marcus Reeve — a performance coach who has worked with world-tour cyclists and midlife beginners alike — teaches you exactly how to raise yours safely, whether you are 28 or 68. You will learn Zone 2 done properly, how to build and periodize VO2 intervals, how to fuel around them, and how to interpret HRV, resting HR, and lactate signals without becoming a data hostage.
