What are Asanas?
Asanas are the first step of the physical aspect of yoga. Patanjali describes them as sthiraha sukham asana, which means any posture taken for stability and well-being. They improve flexibility of the body, strengthen the muscles and give youthful and radiant look to a person. The goal of all asanas is finally to bring harmony between the body and mind so that the awareness can move from the physical body to higher levels of consciousness.

“Yoga is a vast science, an infinite journey that takes you more and more towards the unknown, towards the state of supreme bliss. But its beauty lies in the fact that it starts with very small steps than anyone can take.”

Yoga is known as a stress buster, but it's also one of the most effective workouts for fighting stubborn fat stores, especially the ones that crop up after the age of forty.
  
The reason: Studies show that yoga lowers levels of stress hormones and increases insulin sensitivity--a signal to your body to burn food as fuel rather than store it as fat.
