Not all backbends are created equal!

Not all backbends are created equal. Healthy backbends happens at the lowest lumbar level (L5-S1); unhealthy backbends happen higher up in the lumbar spine.


This yogini is backbending (unhealthily) almost entirely in the upper lumbar spine.


The L5-S1 joint is unique in having saddle-like properties and is capable of quite extreme extension (backbending) without injury. 

B.K.S. Iyengar demonstrates a healthy 90 degree backbend that happens exclusively at the L5-S1 joint. Iyengar was one of the world's foremost yoga teachers until his death at age 95.

 Peking Acrobats are trained to perform extreme backbends. The backbends happen exclusively at L5-S1, which makes them sustainable.

Higher up in the lumbar spine, repeated, sustained, or extreme extension results in wear and tear and injury in the related discs and vertebrae.

This young gymnast exhibits a classic gymnastics pose, with a significant (unhealthy) sway in her upper lumbar spine. Gymnasts are notoriously prone to back pain and injury.


The majority of this dancer’s backbend happens at a single level in her upper lumbar spine that is not adapted for extreme backbending (ouch!).

The distinction between upper and lower lumbar curvature is rarely made, neither for baseline positions like standing and sitting, nor for acrobatic and yoga positions like backbends. This lack of distinction is true in modern lay culture as well as in the medical literature  Not surprisingly, findings involving a crude compound of all lumbar curvature are confused and contradictory. We have found only one scientific study on lower back pain that makes a distinction between upper and lower lumbar curvature. 

To learn a healthy backbend, start with an “infant cobra,” in which you plan on lifting no more than two inches off the ground. Begin by lying face down with your hands placed near your armpits. Before lifting, engage an extremely strong rib anchor. Augmenting the rib anchor hard against the tendency to sway, press up an inch or two from the ground. Keep the neck aligned with the spine.

Notice how in this healthy baby cobra, the backbend takes place only at L5-S1 at the base of the lumbar spine, right above the butt.

Don’t expect to be entirely successful at the start. It’s challenging to eliminate a habitual sway entirely so tolerate a small amount of arching in your back unless that hurts. As you practice, slip a hand back to your midline groove and make sure the arch is not too accentuated.

If you backbend at L5-S1 and strongly engage your rib anchor muscles, the front lower border of your ribcage will not protrude, but rather remain flush with your torso. A bend higher in the lumbar spine will result in the ribs protruding visibly from the contour of the abdomen.

The extent of protrusion of the ribcage is a fairly reliable index of sway in the low back. This bridge position shows healthy spinal curvature, where the backbend happens almost exclusively at the L5-S1 joint. There is no protrusion of the ribcage from the smooth contour of the abdomen.


This yoga student’s backbend happens at L5-S1 (which is good) as well as the upper lumbar spine (not so good) - her rib cage protrudes slightly from the contour of her abdomen.



This student backbends entirely in her upper lumbar spine (ouch) and we see her ribs lift away from her abdomen a great deal.

As you get used to the practice of intensifying the rib anchor corresponding to the challenge that you’re imposing on it, you can increase the extent of your cobra by degrees and perform other types of backbends.

For extreme backbends, we recommend you leave them to the professionals. B.K.S. Iyengar was known to practice yoga eight hours a day. The Peking Acrobats are also singularly dedicated to their craft.  For some of us, bending back in the shower to avoid shampoo coming into our eyes is the most practice we'll have in backbending. Preparing your back for healthy backbending you can use the Shakti Yoga Wheel® by training your lumbar curve and keeping your rip anchor active.
