Stress is not in your head, it's in your heart - this is the key to peak performance that Dr Leah Lagos, an internationally known expert in biofeedback and sport and performance psychology, wants us to know. In this book, she shares with readers for the first time the same program that she uses with top athletes, CEOs, business leaders - anyone who wants and needs to perform at their best. What makes her scientifically proven ten-week programme unlike any other is that she recognises the link between heart rhythms and stress to create specific, clinically tested breathing techniques that allow you to control your body's physical response to stress. She pairs this training with cognitive-behavioural exercises to offer a two-tiered protocol for strengthening health and performance, enabling readers to respond more flexibly to stressful situations, let go of negative thoughts and emotions, and ultimately be more focused and confident under pressure.********************** 'Dr. Leah Lagos is an extraordinary being.
