On a physical level, the backward bending Asanas stretch the abdominal muscles and tone and strengthen the muscles controlling the spine, helping prevent slipped disc and other back conditions. The spinal nerves, which emerge from between the adjoining vertebrae, are also toned. This has beneficial repercussions throughout the body since these nerves give energy to all the other nerves, organs and muscles in the body.  The spinal column is a 'stacked pile' of vertebrae and discs. groups of muscles extend all along it, covering and supporting it from all sides. The muscles themselves are controlled unconsciously through posture, subconscious tensions and 'hang-ups' are often reflected in the tonic activity of the back muscles.  The practice of backward bending Asanas can correct postural defects and neuromuscular imbalances of the vertebral column.  As with all Asanas it is important to perform these practices with proper control and synchronisation of the breath so that the whole group of muscles is uniformly contracted.

Impure blood has a tendency to accumulate in the back region where circulation tends to be sluggish due to continuous maintenance of an upright position. These Asanas will help to circulate, purify and enrich the blood in this region.  Backward bending Asanas create a negative pressure in the abdomen and pelvis, helping neuro-circulatory toning of all the related organs.  They also massage the abdomen and pelvic organs by stretching the muscles in this area, especially the rectus abdomini.
