Most performance problems aren’t obvious. They’re not in your training plan; they’re not in your effort. They’re in the things you consistently ignore.

In this episode, we sit down with Dr Nick Barringer, performance dietitian, former Army Ranger, and expert in human performance, to break down what actually drives performance, recovery, and longevity.

From nutrition fundamentals to injury prevention to the science behind energy, brain function, and long-term health.

This is a deep dive into the unsexy work that keeps you performing at your best when it matters most.
