Using Fatigue as a Motor Learning Constraint

Today’s guest is Dan Cleather. Dan Cleather is a sport scientist, author, and lecturer specializing in biomechanics and strength training. He has worked across elite sport and higher education, helping coaches apply research to real-world performance. Dan is the author of The Little Black Book of Training Wisdom and The Little Blue Book of Training Wisdom, known for challenging conventional ideas and promoting evidence-informed coaching. If you search the internet for training methods and advice, you’ll invariably get a “do this, not that” mentality woven in your brain. The mark of true progress over time, and reaching athletic potential, is more about principles and management than it is picking all the “S-Tier” exercises. Being able to balance paradoxes, hone belief, refine movement and hone the dance of capacity and output defines the training of elite athletes and Olympians. In this episode, Dan discusses everything from developing exercise devices for astronauts in microgravity to the deeper philosophy of how performance truly evolves. We discuss Easy Strength, capacity versus skill development, fatigue as a motor learning constraint, and why adaptation is something we cultivate rather than force. The conversation weaves biomechanics, Tai Chi, Olympic lifting, and the yin-yang rhythm of training into a broader theme: great coaching isn’t about imposing perfection, but creating environments where flow, resilience, and high performance can naturally emerge.
