Chakrasana (wheel pose) is an advanced asana that should only be attempted after you have increased the flexibility of your front side body through regular asana practice. It is recommended to practice this with a teacher present.

You can enter the posture by building-out from bridge pose. Or, you can lie on your back, bend your knees and bring your heals to touch your buttocks. Grab the right ankle with the right hand and left ankle with the left hand. Inhale the hips up, like in bridge, to enter half-wheel, or Ardha-Chakrasana.

Once you are substantially comfortable in half-wheel, you can place the hands, fingers pointed backwards, under the shoulders. On the inhalation lift the hips and extend the arms. Breathe deeply and comfortably. As you increase flexibility and comfort, you can bring your hands and feet closer together (as seen in the picture).
