How To Breathe So Running Feels EASIER!

Mar 23, 2026 · 9 min

After 10 years of competing, studying sports science, and working with hundreds of athletes, I’ve realized something surprising:

Most runners are breathing wrong.

And it’s costing them speed, efficiency, and performance.

In this episode, I break down 5 simple, science-backed breathing techniques you can apply immediately to run faster, feel more relaxed, and stay in control—even during hard efforts.

We’ll cover:

  • How to activate your body before a run so you don’t feel sluggish in the first 10 minutes

  • Why feeling out of breath is more about CO₂ than oxygen (and how to fix it instantly)

  • How to use rhythmic breathing (3:2 pattern) to improve efficiency and reduce fatigue

  • The difference between chest vs diaphragmatic breathing (and why it matters more than you think)

  • A simple breathing routine to recover faster after your runs

If you’ve ever felt like your breathing is holding you back, this episode will change the way you run—starting today.
