Is Zone 2 Cardio Overrated?


Massive thanks to everyone who filled out the survey, really really appreciate it!

It looks like there is interest in the "Done for you cardio for meatheads" which is great since I've been working it in the background for a couple months. More details soon on it.

And speaking of cardio for lifters, you are going to love this Flex Diet Podcast as I sit down with Dr. Martin Gibala, Professor of Kinesiology at McMaster University.

He is the go to researcher on high-intensity (HIIT) and sprint interval training.

Can short bursts of hard cardio outperform hours of Zone 2 for the average person?

We discuss how HIIT can improve VO2 max and metabolic flexibility, and why an elite athlete's 80/20 split may not fit your time-strapped schedule.

We also get into Zone 2 definitions, wearable confusion, endurance training, and where the evidence stands on newer recovery ideas.

I got served an ad that hit two of my favorite internet-science buttons at once: Soviet sports science and a recovery claim so precise it practically arrived wearing a lab coat: “In 1978 Soviet Sports Scientists discovered muscles rebuild & recover 2.5x faster with slow breathing immediately after your workout.” Well $hit. Anything old and Soviet must be true cuz SuperTraining… Throw in a grainy photo of some doooode wrestling a bear between squat sets and we basically have enough proof of...
