If you are pressed for time and looking for a single mantra to stay fit, here’s the answer. A set of 12 powerful yoga asanas (postures) that provide a good cardiovascular workout in the form of Surya Namaskar. Literally translated to sun salutation, these postures are a good way to keep the body in shape and the mind calm and healthy.
Surya Namaskar is best done early morning on an empty stomach. It can be done as a drill also.
