Ashtanga centers on a vigorous physical practice that includes a series of poses linked together with breath to form a continuous sequence. The practice demands an intense level of physical strength, flexibility, and endurance, which explains why many people see it as a rigorous and challenging workout. Whether you’re just starting out in yoga, or looking for something new as your goals change, adding an Ashtanga yoga class to your daily workout is a good way to keep your mind and body healthy and strong.
