“Psychological flexibility is thundering into sport and mental performance coaching because it opens up new and effective ways to think about training, toughness, competition, and life balance. The Flexible Mind leaves no stone unturned in its honest, thorough, and skillful application of the model to that most human of all human behaviors: organized athletic competition. I learned something on almost every page. Highly recommended.”

This is an important book: accessible, practical but with real substance. It distils one of the fastest-growing models of how humans react to their situation and tailors it beautifully to the needs of athletes and their coaches. In a world of individual, gimmicky ideas, its expert authors bring you real science applied to real performance and well-being issues.”

"Some approaches are enlivening and inspirational but aren’t supported by science. Other approaches might be backed up by good evidence but aren’t accessible or usable. The Flexible Mind is a rare gem that inspires the heart and guides the mind using the cutting edge of our science, with a whole lot of soul. I give this book my highest recommendation."

Dr Dennis Tirch

“An excellent introduction to The Flexible Mind approach and key reading for those interested in using Mindfulness- and Acceptance-Based approaches in sport. The authors have developed a very accessible and informative book packed with helpful vignettes, practice guides, case examples, and session plans"

Dr Chris Wagstaff

“Flexible Mind provides the reader with solid theory and research on the psychological issues that face athletes. And then, they go one step further and provide a very engaging read, with memorable ways to enliven the work, and it all comes together as a very useful resource. I can see this as being very welcomed by all those who work with athletes. A great handbook to give to coaches. Many aspiring athletes are still very young adolescents and helping them manage their skill along with their mental wellbeing is critical. If you work in this field, I think this is essential.”
