The benefits of yoga are huge, not only do they improve your physical strength, but increase concentration and memory and actually teach you how to relax. I teach yoga to children, and the reason I started to do this was because I saw what benefits it had to myself and thought why should children not receive these benefits also.
One thing I love in my life is yoga. No matter how hectic life is, yoga allows you to take a small amount of time out. I believe it is more important that ever to allow time for yourself as generally more is demanded from us and life is becoming more and more stressful. Many people think they are unable to do yoga as they are too unfit or not flexible enough. This is a myth as anyone can start yoga. It is progressive, the more you do it, the stronger and more flexible you become in body and mind.
