How to Do Fire Log Pose - Agnistmbhasana
Knee to Ankle - Agnistambhasana. Ann Pizer
  • Also Known As: Double Pigeon
  • Type of pose: Seated
  • Benefits: Opens the hips

Agnistambhasana has a lot of English names and they are all pretty accurate descriptions of the alignment of this pose. Fire log is the most direct translation. It refers to the shins being stacked one over the other to look like pieces of wood in a fireplace. Knee to ankle also works, since each knee should be directly matched up to the opposite ankle. I've noticed that using the term double pigeon seems to be coming into favor. It makes sense since both legs closely resemble the position of the front leg in pigeon. Keep in mind that in the ideal version of pigeon, your front shin isn't angled back toward the opposite hip but is rather parallel to the front of your mat.

The most common issue with this pose is a tendency to let it shift into something that more closely resembles a half lotus. The top knee slips out wider as the top foot comes away from the ankle and toward the inner thigh. That's because keeping the shins lined up and stacked is hard. That's where props come in. It's more true to this posture to use a block under your upper knee than to just let that knee slide out of position. When done correctly, your two thighs and the shins form a tight triangle. Opening the thighs further makes it a different pose.

If knee pain is a problem for you, approach this pose with caution. It is a vulnerable position for the knees when done incorrectly. Remember that you can always skip a pose that's not a good fit for your body.


  1. Begin in a comfortable cross-legged position.
  2. Bring your right shin parallel to the front of the mat.
  3. Stack the left ankle directly on top of the right knee, bringing the left shin parallel to the right. 
  4. Flex both feet.
  5. Repeat on the other side.

Beginners' Tips

  • Sit on a folded blanket if your knees are well above your hips when you sit cross-legged.
  • If there is a lot of space between your top knee and your bottom ankle, position a block or blanket to fill the gap for support. You can do the same thing if there's a space between your bottom knee and the floor.
  • If you feel knee pain in this pose, skip it.

Advanced Tips

  • Keeping the spine long, come into a forward bend. Pause with the elbows on your top shin to deepen your legs. Sometimes this gentle pressure can help close the gaps between knee and ankle.
  • You can continue forward to place your forearms on the floor in front of you if you can do so with a flat back.
