Ashtanga is among the oldest forms of yoga, recorded by Vamana Rishi. It was a yogi by the name of Patthabi Jois who popularized this style in the early 20th century. In this form of yoga emphasis is placed on vinyasa, in which movement and breathing are done fluidly, and each pose is done in one breath. Ashtanga yoga is meant to be done on a daily basis, with six different parts in all. The time it takes to get through all six depends on experience and fitness level.

The ashtanga series begins with Yoga Chikitsa, or yoga therapy, and includes 75 poses. They are for the serious yoga practitioner, as it can take up to three hours to complete them all. It is worth it, though, as these poses realign the spine, increase flexibility and improve muscle strength. Other benefits include relieving stress and reducing the toxins in the body. After these poses are mastered, the second group of poses, or Nadi Shodana are begun. Sthira Bhaga, or the last four parts of Ashtanga yoga, is complex and difficult. These poses include arm balances that require strength and discipline.

An important part of Ashtanga Yoga is the heat in produces within the body. The profuse sweating that is a part of this method is meant to cleanse the body and thin the blood. This is done to improve circulation and reduce muscle and joint pain. By heating up the blood during these poses, the impurities and disease within the body are thought to be removed through the prolific sweating.

The Ashtanga system is a very intense, physically demanding form of yoga. It is not only about physical fitness, but mental fitness as well. The inner peace and energy that are brought about can be life changing. Ashtanga, like all other forms of yoga, work best when done in conjunction with meditation and a healthy diet. Many who follow yoga find a vegetarian, organic diet beneficial. By eating only healthy, natural foods, the benefits of Ashtanga are greatly increased.
