Yoga is one of the six systems of Indian philosophy originating from the Vedic tradition. Today's popular concept of yoga is most commonly associated with Hatha yoga, a branch of yoga that emphasizes physical postures (asanas) designed to enliven proper functioning of all of the bodily systems. Yoga asanas, have become popular around the world as a form of physical exercise which promotes relaxation, mental calm, physiological flexibility, strength, perfect health and reversal of the aging process.

In 2014 an international day for yoga was declared unanimously by the United Nations General Assembly, with the first celebration on June 21, 2015. Originally proposed by the current Prime Minister of India, the celebration is meant to honor yoga as one of India's gifts to the world. Embodying unity of mind, body, thought and action, yoga offers a holistic approach to health and well-being.

The ideal of daily practice of yoga asanas is not to strain to attain a pretzel position, but rather to gently stretch the body with the understanding that regular practice will make the physiology more flexible and ideal. As a side benefit, internal organs are nourished in a manner which promotes optimal functioning.

Some of the popular poses are outlined below.
