Yoga develops inner awareness. It focuses your attention on your body's abilities at the present moment. It helps develop breath and strength of mind and body. It's not about physical appearance.
Exercising regularly, every day if possible, is the single most important thing you can do for your health. In the short term, exercise helps to control appetite, boost mood, and improve sleep. In the long term, it reduces the risk of heart disease, stroke, diabetes, dementia, depression, and many cancers.

Belief in God
Belief in God is belief in your own as in; the way you are known to yourself nothing else is known. The parents are the visible God and the God is our invisible parent who is always with us in all the circumstances. All of us are from religious backgrounds somewhere so we are known to it that whatever the situation will be there our Almighty father will always be there for us to keep us safe and happy. As much as you go near to the God he will come more close to you. Believing in God makes you fearless, free from all the worries, sets you at a level of stability and significantly makes you live the life in a lovely and peaceful way like he wants his children to live it.

It's all about that Belief.
