Applicability of Isometrics in Sport Programs

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.

With a background in both applied coaching and academic research, Dan has worked extensively in elite sport and higher education, bridging the gap between theory and practice. He is the author of The Little Black Book of Training Wisdom and The Little Blue Book of Training Wisdom, where he challenges conventional thinking and promotes evidence-informed coaching. Dan is known for his clear, analytical approach to training science and his ability to translate complex biomechanics into practical strategies for coaches and athletes. Zac currently treats clients and consults internationally, while continuing to produce educational resources aimed at elevating the standard of movement practice in both clinical and performance settings.
