In Yoga: Bend Back, Don’t Swayback!
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 (see post on Forward Pelvis) as well as in the medical literature (see this cross sectional study on the Correlation between Radiologic Sign of Lumbar Lordosis and Functional Status in Patients with Chronic Mechanical Low Back Pain). Not surprisingly, findings involving a crude compound of all lumbar curvature are confused and contradictory. I have found only one scientific study on lower back pain that makes a distinction between upper and lower lumbar curvature - the findings are consistent with the Gokhale Method's claims about a "J-spine" being healthier than an "S-spine."
I consider that the significant back problems I suffered in my mid-20’s resulted in part from poorly executed yoga and gymnastic backbends in my childhood, as well as a chronic baseline extension (sway) of my upper lumbar spine. I was rewarded for my “flexibility” both in gymnastic competitions and as a yoga presenter and teacher—I received applause, awards, and signups for classes. Almost no one saw that I was systematically bending backwards in a problematic place.

I do recall my Bharatanatyam dance teacher Kutti Krishnan being vaguely disturbed by my baseline stance. He wasn’t able to articulate what exactly the problem was, or how to correct it, but I remember him trying to imitate my stance to help me out. It didn’t work, he stopped trying to correct me, and my sway persisted unchecked into adulthood, when it manifest as a problematic and then surgical back in my mid-20’s.

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. It's enough to keep us flexible and healthy as we enjoy watching what others are able to do.

As always, my statements are
Hi Marilia,
As always, my statements are based on visual and kinesthetic observation (as well as several other people's observations), study of the medical literature (check the bibliography of my book) as well as intellectual arguments (though these are weighted less than empirical observations).
You clearly have a different opinion and you are entitled to it, but I question some of your arguments.
In the end, it's important to do what feels best for your particular body, and I'm glad you've found something that works for you. But I believe the pictures and arguments I am putting forth are worth considering.
Some of information on here
Some of information on here is not factual in and is quite opposite of what you should tell people for backbends. The number one back injury is lower back and this is because people will either improerly use back muscel instead of their core or do backbends putting too much of the bend in the lower back, especially the L-5 S-1 area. For with pre-existing issues this advice would be detrimental.
Being a yoga teacher and having trained for many years prior in gymnastics, dance and diving, I can tell you the reason for back injuires in these sports IS NOT from the backbend being in your upper back. It's quite the opposite. Most injuries happen 1) from high impact and not engaging your core to support the spine in high impact bending (such as front handsprings, jumps with an arch, diving when you enter at an angle that puts more pressure your back, also falls) 2) backbends getting stuck in the lumbar spine. When the backbend is centered in this region it compresses the vertebrae. By putting more emphasis on elongating through the spine and legs it takes the pressure out ofthe lower spine. A healthy backbend should be finding length first and balancing the stretch throughout the spine not centralizing. This practice has helped me cure my back pain and the only times I experience pain is when I am not being as present and allow lumbar spine to take most of the bending. Not safe.
My back has been sore (even
My back has been sore (even bruised feeling) from doing back bends but in the upper lumbar/low thoracic area. How do you recomend changing that bending point? I'm thinking more core strength so it will brace properly? Maybe work on my hip flexibility? I've always wanted a good back bend, but even after gaining a lot of shoulder mobility(which I thought was my issue) I still am not very good.
thanks for any advice!
