The kidneys are connected to the second chakra, which is located in the lower abdomen and the element of water.

Physiologically, hatha yoga works on the hips, lumbar, and sacral regions to stimulate this energy. Specific asanas can also aid in maintaining and stimulating the healthy flow of fluids in the body, which improves kidney function and revitalizes energy in the second chakra. Such fluids include the synovial fluids of the joints and the fluids of the lymphatic system as well as a healthy level of blood and urine production.

Asanas that simply put pressure on the kidneys also help to flush and cleanse these organs.

The meridian line, or energy line, that stimulates the kidneys runs from the bottom of the fifth toe and through the inner knee, thigh, and sacral region. Twists, back bends, forward folds, and inner thigh stretches will stimulate the second chakra and release blockages.
