Gregor has had a profound influence on the modern practice of Ashtanga yoga through his seminal book Ashtanga Yoga Practice in Theory, published at a time when most of us thought technique in yoga was just pushing as hard as we could against our limitations. His anatomical approach to the Ashtanga system has been indescribably beneficial, as has his attempts to frame the asana part of Ashtanga that we often take as the sum-total of our yoga practice, back within its original, broader context as only one of Patanjali’s eight limbs. Gregor lives a life of yoga in earnest. Having embarked on this path whilst still a teen in his native Germany, his inquiry led him to many years of study in various yogic traditions travelling widely throughout the subcontinent of India. He now lives in Australia with his wife and fellow teacher Monica Gauci with whom he has co-written many of his books.
