In today's running culture, people can't stop talking about Zone 2 running. But what about Zone 3?

John Davis is an author, running coach, former collegiate runner, and an expert in human performance with a focus on biomechanics.

He ran at Carleton College before getting a PhD in biomechanics at Indiana University's School of Public Health, focusing on running injuries.

In this episode, we talk about:

The underutilized value of Zone 3 running
Why zones aren't as clear as many people make them out to be
Lactate threshold and steady-state max in running
High-end aerobic training and its effects on muscle fatigue
Improving aerobic capabilities with middle intensity training
Main drivers of fatigue in different intensities
Training in Zone 3 and how it can predict performance in endurance events
Balancing physiological principles with practical coaching

Send this to your running group chat so you can unpack the myths and science behind Zone 3 on your next group run!

Thank you Previnex!

After resisting most supplements for the better part of my life, I’m cautiously changing my tune. I’m now a Masters runner and in my personal life, I’m optimizing for longevity. I want to be my healthiest self for as long as possible and I’m excited to partner with Previnex to make that happen.

Previnex uses the most bioavailable, clinically tested ingredients, the optimal form and dose of each ingredient, pharmaceutical grade manufacturing, testing of raw ingredients and finished products. For every purchase you make, they also donate vitamins to kids in need.

Their new Muscle Health Plus is something I'm now taking. Turning 40 - and having a thin frame - has made me realize that I need to prioritize lean muscle mass to stay healthy and age well. Muscle Health Plus has creatine, essential and branched chain amino acids, and it's designed in a way to maximize protein synthesis and the absorption of amino acids.

Muscle Health Plus will help you prevent muscle damage, which is particularly important for aging runners who want to protect themselves from muscle loss and recover faster after hard workouts. As is true for all of their products, Previnex adheres to the highest of standards: their ingredients are clinically proven to do what they say they’re going to do.

Previnex offers a 30-day money back guarantee. If you don't feel the benefits of their product, you get your money back no questions asked. With their focus on quality and customer satisfaction, I hope you’ll try it! Use code jason15 for 15% off your first order at Previnex!

Thank you MOBO Board!

Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that’s set up on two fins. The design effectively forces you to drive your big toe into the board to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly!

Even if you’re a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You’ll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it’s not just how strong you are, but how well you use that strength.

I was recently at a weekend physical therapy workshop (lol I was the only running coach) and learned how important (and rare) this simple movement is. Save 10% with code STRENGTHRUN10 at checkout at moboboard.com.
