Think fatigue is just about feeling tired? Think again.
In this episode of The Progress Theory, I sit down with Dr Callum Brownstein, physiologist at Newcastle University, to explore the real science behind fatigue—how it works, what drives it, and how to manage it to maximise your athletic performance.
Whether you're a runner, cyclist, or general fitness enthusiast, understanding why you fatigue and how to recover properly could be the game-changing knowledge you’ve been missing. Dr Brownstein breaks down the difference between central fatigue (brain and nervous system) and peripheral fatigue (muscles), and how training type, intensity, and volume can impact both.
If you want to stop guessing and start training smarter, this episode is essential listening.
In this episode, we explore:
🧠 The difference between central and peripheral fatigue
🚴♂️ Why cycling and running create different fatigue profiles
📈 How intensity and volume affect recovery
🗓️ How to organise your training week to reduce overload
⚖️ Pre-fatigue strategies and training session sequencing

Key Takeaways:
🔬 Understanding Fatigue Mechanisms: Know the difference between brain-driven and muscle-driven fatigue to improve your recovery and planning.
🔁 Modality Matters: Running often leads to central fatigue, while cycling triggers more muscular (peripheral) fatigue. Train accordingly.
🧘 Discipline in Intensity: Keep easy days easy—going too hard too often is a one-way ticket to burnout.
