How Breathing Affects Posture and Spinal Flexibility

As long as we are alive, we are breathing! So it is very useful to understand how breathing affects both our posture and our spinal flexibility. Many different muscles participate in the breathing process, and breathing is one of the few physical functions that is both automatic and under our control. While there is no wrong way to breathe, taking control of our breath and learning to strengthen our central breathing muscles like the diaphragm is a great tool to improve many aspects of our physical and emotional state, including posture and spinal flexibility.

How We Breathe Affects our Posture

The spine is designed to be extremely mobile, able to move forwards, backwards, twist, and side bend. For more information on spinal mobility check out this blog post on spinal anatomy for back benders.

The ability of our spine to take advantage of this exquisite range of motion depends in part on our posture. If we habitually stand and move in ways that force our back muscles to become tight and over-worked, we will find ourselves with tension, even pain. The muscles in our back and neck can become resentful and stressed out. The way we breath can either help or hinder our back’s ability to relax and feel full mobility.

Breathing Can Relax the Spinal Muscles

One of the most important skills we need in order to relax our spinal muscles is the full exhale. When we exhale all the way our rib cage drops down away from our chin and our diaphragm relaxes, created a dome shape up inside our rib cage. This big, muscular dome, even relaxed, provides a lot of support for the rib cage (called the zone of apposition), so when we exhale fully our upper back and neck muscles get a little break, lengthen out, and the rib cage just floats on that diaphragm.

Surprisingly, many of us don’t do a great job of exhaling. As I explain in my blog post on core muscles and how they coordinate together, a full exhale and relaxation of the diaphragm requires a corresponding increase in participation from the “meat corset” muscles that wrap around your waist (the transversus abdominus, the internal obliques, and the external obliques) as well as the pelvic floor muscles.

If we have neglected to develop our relationship with this group of core muscles, it will be hard for the diaphragm to relax and therefore we will never get that corresponding relaxation in our upper back and neck muscles.

10 Minutes of Breathing to Improve Posture and Spinal Flexibility

I created a 10 minute series of exercises that guide your body through a coordinated breathing routine that facilitates these long, complete exhales while encouraging your waist muscles to participate while your neck and spinal muscles to relax. It is a series of four exercises in increasing levels of challenge, each one building on the last to develop the deep awareness of both diaphragmatic relaxation and core engagement, with a little spinal flexion thrown in since this is the first direction that we want to spine to go if we are working to increase spinal mobility.

All you need to try it out is a spot on the floor and a few pillows to get comfy. No previous fitness experience or flexibility is needed to do this. It is an exercise for any body. If, as the exercises progress, you find yourself feeling tension in your back or unable to find the meat corset muscles, just go back to the first exercise for a while.

This series is a good way to start to strengthen your core muscles if traditional ab strengtheners like crunches feel awkward and miserable, or cause your neck and back to over work. It is also an excellent warm up for a core workout like Pilates, or for anything involving spinal flexibility like contortion, pole, dance, or yoga.

Spinal Anatomy for Back Benders

Back bending is one of the most challenging areas of the flexibility arts. The spine is an extremely complex structure consisting of bones, cartilage, connective tissue, and tons of nerves. You are essentially bending your brain’s tail.

Back bending is also special because most of the flexibility gains come from shortening the muscles of your back. Most flexibility training focuses on lengthening muscles. That is why back bending feels so different than other types of stretching and why it requires a specialized, primarily active (strength-based) approach. For ideas on strength-based spinal mobility check out the Video Club series.

Back bending is intense! Moving those bones and nerves around can create all sorts of unexpected responses. Dizzyness, euphoria, nausea, headaches, intense emotion, muscle spasms, and exhaustion are all common responses to back bends. My coach used to say that one hour of backbending taxes the nervous system like eight hours of normal exercises.

And of course back bending can be dangerous. Overtraining risks the possibility of fractured vertebrae, herniated discs, pinched nerves, and chronic pain.

Lest I sound like a total downer, I still love to teach and practice back bending. I just have strong feelings about the need for education and safety around the pursuit of the back bend. So let’s start with understanding the basics of how the spine is constructed.

 

The Three Segments of the Spine

Outline of the Spinal Anatomy

The spine is made up of 24 boney chunks (vertebrae) that are hollow in the middle to allow the spinal cord to pass through. In between each vertebrae is a squishy disc to allow for movement and protection, and there are tough cords of ligaments that keep everything held together. To nerd out more deeply on the anatomy of the spine check out this good introductory article from the University of Maryland Medical Center.

Vertebrae change shape as they go up the spine. Based on that shape the spine can be divided into three different sections. Each section has a different kind of movement function.

Lumbar Spine

The Lumbar SpineThe lumbar spine starts at the sacrum, a flat shield-shaped bone that attaches to the pelvis. The five lumbar vertebrae (some people have six) are the largest of the three sections and naturally curve into a back bend shape. Some people have a lot of natural curve, some people have less.

The primary muscles supporting the lumbar spine are the illiopsoas, transverse abdominus, obliques, and the pelvic floor muscles. The muscles in the back that need to shorten for backbends are the multifidi, quadratus laborum, and the large muscles on either side of the spine that connect the spine and the ribs.

The shape of the lumbar vertebrae makes them more mobile going forwards and backwards although they also allow for twisting and side bending. Your lower back is part of the support system for your entire upper body, so it is important to keep it strong and mobile even if backbends aren’t your passion.

If back bends are your passion, beware over-using your lumbar spine. Because it has a natural back bend curve it’s easy to dump into your lower back, especially if you have a lot of natural curve and/or tight hips and upper back.

 

Thoracic Spine

The Thoracic SpineThe thoracic spine is the longest section of the spine, starting in the mid back and extending up to the base of the neck. The shape of the vertebrae differs considerably from the lumbar spine allowing for less mobility. The thoracic vertebrae are also the anchors for the ribcage, further limiting movement potential.

The muscles that support the thoracic spine in backbends are primarily upper back muscles including the lower and mid trapezius, the serratus anterior, and the rhomboids. The diaphragm is also involved in upper back bending and a tight diaphragm can limit upper back mobility.

The thoracic spine has a natural forward bend that is often exaggerated by modern posture. This is why learning how to find a backbend in the thoracic area is valuable even if you aren’t a back bender. And if you are a back bender it is extremely important to develop the muscles that reverse the natural curve of the thoracic spine to avoid over-using the lower back and neck.

The thoracic spine is very good at twisting, so one entry point it to work on twisting motions.

Cervical Spine

The cervical spine is in the neck, providing the bridge between the skull and torso. There are seven cervical vertebrae designed for maximal movement in all

directions: forward, back, tilting, and twisting. This is necessary for us to have the mobility we need but it does mean that back benders (and everyone else) need to take very good care of our necks.

Like the lumbar spine, the cervical spine also has a natural backbend shape. That makes the neck another vulnerable place for back benders. I often teach backbending without including the neck at all until some amount of thoracic bend is present to lessen the pressure on the cervical vertebrae. Strengthening the neck muscles is also essential, especially for those planning to practice chest stands (locust pose) or shoulder stands.

 

It is important to strengthen all of the neck muscles evenly because it is so mobile. Don’t just work the back bending range, work forward, tilt and twist with resistance. That head weighs about 11 lbs. It’s heavy!

 

 

Know Your Bend

Understanding the sections of the spine and how they work will aid you in improving the beauty and ease of your backbend and making sure that your back stays healthy and pain-free.

Pro Tip:
Take some photos of your backbend. Notice where you are bending: which areas of your spine are doing the work? If you notice that you are only bending in a few spots and other areas of the spine are not bending at all, or eve bending forwards, this is a good indication that you should focus your training on evening out that bend before going deeper into your flexibility.
