Yoga is basically a form of exercise that people take up so as to stay fit and healthy. Yoga is a form of meditation too. Yoga helps you staying physically as well as mentally fit. Yoga can be practised in the presence of a yoga instructor. Yoga helps to transform you into a fit and calm person who is an asset to any society that he is a part of. Yoga also helps you to have glowing skin and provides you that “feel-good” factor which many other exercise forms don’t. Yoga can be practised to cut down some flab and have a proportionate body. Power yoga is basically used for this purpose. Yoga exercises make you quite flexible too. In the words of Mariel Hemingway, “A lot of exercise is mindless; you can have music or the radio on and not be aware. But if you're aware in anything you do - and it doesn't have to be yoga - it changes you. Being present changes you.”
