Yoga, which means discipline, was developed in the year 300 by a Hindi devotee. Its purpose is to stretch the muscles, strengthen the body and increase concentration. It can also help you relax.
Some who practice yoga, called yogis, try to use the discipline to reach a high level of consciousness like practicing being clean, content, self-controlled, studious and devoted.
Physical control is also important in yoga. Yogis train themselves to take full, deep breaths. They consider breathing a life force, counting a lifespan not in years but in the number of breaths taken.
Unlike exercises that work only on strength, yoga also helps the body become flexible. As a result, some yoga exercises (called asanas) look a little strange, and you may think you need to be a human pretzel to do them. Not so. You just have to relax.
All yoga exercises promote strength and calmness. Each move's effects on a muscle, a gland or a nerve center are carefully thought out.
You can choose certain exercises to rid yourself of particular pains, such as back pain from back-packing or leg pain from jogging. Yoga can help condition you for skiing or help you control feelings of depression or fear.
