According to Yoga Journal, there are 16.5 million yoga practitioners in America and they spend almost 3 billion dollars on classes and products each year. Author Ulrica Norberg suggests that yoga can aid us in developing our own life philosophies through a synthesis of Eastern ideology and an expanding understanding of ourselves. She takes readers through the elements of East Asian philosophy, the history and composition of yoga, and the basic movements and techniques specific to the dynamic yoga form of power yoga. Filled with beautiful full-color photographs illustrating sun-salutation (the basis of power yoga exercises), numerous asanas (poses), and relaxation techniques, her book is useful for all levels of instruction and inspiration.
