When most athletes think about hitting a performance wall, they blame tired legs, high heart rates, or poor lung capacity. But there’s a hidden factor that can silently sabotage your endurance: the respiratory metaboreflex.
In this video, Dr. Jay explains how this powerful reflex can shift blood flow away from your working muscles and toward your fatigued breathing muscles — making your legs give out sooner, even if your heart and lungs still have more to give!
In this video, you’ll learn:
- What the respiratory metaboreflex is
- How poor diaphragm conditioning or hyperventilation can trigger it
- Why it robs blood flow from your legs
- How to test and train your breathing muscles
- How VO2 max testing + breathing assessments can help
If you’ve ever felt like your legs fail before your lungs do, this is the missing piece you need to know. Don’t let poor breathing mechanics limit your performance!
