Bhujangasana is known as the snake or cobras pose because it reflects the look of a raised hood. As you raise your head along with your chest it represents a snake hood. The rest of the body lies down representing the body of the snake. This asana can be one of the best asanas for your back as well as your spine.
Inhaling and exhaling plays a very important part in this or any other asanas. Bending and stretching of your back may differ between individuals. As some has their youth to help whereas some manage even without that. It all depends on how flexible your body is and how much can you bend, to make the utmost use from your asana.
It has been said that, as long as your back is flexible you still have a long way to go. Every muscle of your body is pulled and stretched which gives the elasticity and suppleness to your backbone. With the passing of age our back starts throwing tantrums and becomes very stiff against our wishes. Before any such thing happens tone your body and other parts of your body by doing this asana.
By stretching, it tones the spinal column which reflects your back and with the extra pull entire abdominal muscles get toned too....
