I was like nobody back then, and I believe many people thought the VO2 Master was just a cool accessory and not an advantage in training. VO2 Master is super useful, it’s like taking the lab out to the training field where I train day to day. Being in a lab is great but its not the environment where I perform and the VO2 Master allows me to get accurate measurements, out there wherever I train, to get the numbers I get.
