Ashtanga yoga (also spelled Astanga) is a traditional style of yoga practiced across the world and popularized by celebrities like Madonna and Sting. Vigorous and physical, the practice of Ashtanga yoga challenges the participant's strength, flexibility, breathing techniques and concentration. Literally translated, Ashtanga means "eight limbs," and refers to each person's eight spiritual channels. The traditional practice of Ashtanga yoga was translated from an ancient text called the Yoga Korunta by Prattabhi Jois in 1958.

A typical Ashtanga yoga session moves through a series of postures (asanas) which are linked together through movement and breathing techniques, allowing for a flowing structure to the practice. Ashtanga yoga typically begins with a number of sun salutations -- there are two different types, A and B -- and many of the movements are linked together by a vinyasa, a flowing movement meant to generate energy and cleanse the body. Traditional Ashtanga yoga can involve 75 different postures, including standing poses, seated poses, inversions and backbends, and can last up to two hours. Throughout the practice, participants use a deep breathing technique called Ujjayi breath, which channels air through the back of the throat.

Ashtanga yoga is best practiced in a teacher-led environment, but because of its structured approach it can be done independently by experienced yogis. Ashtanga yoga is the basis for power yoga, a fast-moving athletic variation of the traditional practice.
