Brady Holmer knows a lot about running and a lot about science: a perfect combo for a conversation on the Strength Running Podcast.
Brady is a lifelong endurance athlete who competed in cross country and track for Northern Kentucky University and continues to run recreationally. He currently works as a science writer and researcher in Austin, TX, holding a Bachelor’s degree in exercise science and a Master’s degree in human performance.
He’s not just smart; he’s fast. Brady recently ran his personal record in the marathon with a 2:37 flat just last month.
You might recognize his work through the Physiologically Speaking newsletter. (Definitely subscribe if you don’t read it yet.)
Heart rate zones are a big conversation in running these days.
Brady and I met to examine the common notion that Zone 2 running is the end all, be all of training. (Spoiler: It’s not.)
There are a lot of silly ideas out there, from wanting to never run outside of Zone 2 on easy runs, to thinking all of your training should be in Zone 2, and even that a Zone 3 effort is somehow harmful or should be avoided.
So let’s dig into what actually matters.
Brady Holmer on Heart Rate Zones, Effort as a Metric, and Paces
Let’s bust some myths! In this episode, Brady Holmer and I talk about:
- The flexibility of heart rate zones and their impact on training adaptations
- Physiology is constantly fluctuating: zones aren’t static
- RPE (rating of perceived exertion) is a valuable metric for runners
- The 80/20 rule of running: 80% lower intensity and 20% higher
- Benefits and nuance of Zone 2, Zone 3, and Zone 4
- Zone 3 training is complicated, but not pointless
- When to ignore heart rate during runs
- Maintaining intensity during hot weather
- Running in summer heat leading to higher heart rates and increased cardiovascular drift
- Heat acclimation and its benefits for runners (and also cooler weather benefits)
- Bike intervals for adaptations and injury prevention
- Finding optimal running paces

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.
