Power Yoga is any of several forms of energetic vinyasa-style yoga as exercise developed in America in the 1990s. These include forms derived from Ashtanga Vinyasa Yoga, namely those of Beryl Bender Birch, Bryan Kest, Larry Schultz, and forms derived from Bikram Yoga, such as that of Baron Baptiste.
Rather than treating each pose individually, power yoga focuses on the flow from one to the next. Unlike some other types of yoga, the poses are not isolated from one another. Power yoga, whatever you call it, is a fast-paced and intense practice. You quickly shift from one posture to the next, synchronizing your breathing to your body’s various motions.
