The origins of yoga are difficult to pin down. Its roots reach far beyond the written history of humankind. It is considered to be as old as humanity itself. The oldest documents relating to yoga are several 5,000 year old seals discovered at Indus Valley Civilization sites. They depict figures in positions resembling common yoga poses. Yoga is often considered as an extension of Hinduism. However, yoga is not a religion. It is actually a philosophy which predates all major world religions including Hinduism. It has also come to be accepted as a sport since it can be practiced to renew the body. Yoga is a kind of body exercise which adds flexibility, control and spiritual tranquility to the existing benefits of Pilates which improves balance and strengthens the body. Yoga exercises improve blood circulation and help ease muscle strain. It is both elegant and safe. Focusing on breathing slowly and deeply slows down the heartrate and thus helps the practitioner feel comfortable and relaxed. It also improves balance by strengthening the major muscles in the body. Bending forward is an easy exercise and can be conducted anywhere. Also, practitioners stand up and lift their arms above their heads and point them upwards. They take a deep breath. When they exhale, they bend forward at the waist and stretch their hands towards the floor. Practitioners remain in this position for three consecutive breaths and return slowly to their original position by straightening the back. These exercises strengthen the abdominal and back areas equally and help build a robust skeletal structure on the upper part of the body.
