The ONLY Person Who Can
PREVENT Yoga Injuries is YOU!


Because Ultimately, there are NO totally omniscient teachers or gurus or masters or even No More Aging: Yoga Injury Preventiontherapists who can tell exactly, for sure, what’s going on in any particular yoga posture in your bodymind, nor know For Sure they can offer you FULL yoga injury prevention.

Even the top teachers or “World Class Masters” in yoga have occasionally misread the body of a student and pushed them WAY too hard, causing injury. …

Sometimes, severe injury.

In some cases, the damage is immediate, in others, the damage is more subtle and incremental, very slowly accumulating over months or even years. A few of the injured World Class Yoga Teachers took DECADES before they realized they were on their way to a Bad Scene and ended up with surgeries of the hip, knee, low back, or other body parts.

Yoga Injury Prevention Is Up To YOU!

Your Instructor WON’T Always Know!

It is, therefore, YOUR responsibility to learn & develop your own INTERNAL ABILITY to Monitor & Moderate Yourself such that you do not get yourself into situations causing injury. This is about increasing your internal sensitivity and ability to interpret what’s REALLY going in your body & mind, and developing better, more “kinesthetically intelligent” ways to respond to what you feel.

with Your Instructors:

They can give you feedback, they can suggest, they can even verbally encourage you to, for example, see if you can go deeper into a posture, or change the angle of movement. …

But only under your own power,
NOT with the instructor forcing you. …

Yoga should NOT be Marine-style Bootcamp!

They can even give you gentle prodding or subtle “adjustments” SUGGESTING where your body should go, yet without either you or them forcing it.

BUT, the Agreement is they WILL NOT verbally intimidate or physically force you to do anything you are not VERY sure your body is ready for. … Yes, you might not get as deep, as fast into your yoga postures, nor will you even CARE (ideally). … But you will stay MUCH safer.

Paradoxically, if improving your over all HEALTH is of a higher priority, you will get FAR more benefit from this approach to your yoga.

LOW Intensity Yoga

I call it Minimum to Moderate Edge Yoga, relying more on naturopathic principles of natural healing rather than aggressive fitness principles. … You need to spend some time doing yoga at low levels of intensity, NOT going vey deep at all. Here, your objective is to get to KNOW your body more intimately. High intensity sensations actually inhibit or block the more subtle sensations you NEED to more intimately FEEL.

Yes, yoga can be used more for fitness if you want, but Fitness and Health are on two ends of a spectrum. It is very difficult, if not impossible, to do ONE type of exercise to develop both ends of the spectrum.

That principle is described in my FREE Infographic on Common Causes of Yoga Injury, available HERE. OR, click the mini-version of the Infographic off to the Right ===>>>Common Causes of Yoga Injury for Yoga Injury Prevention

The Consequences of not following these or similar instructions or guidelines can lead to a host of problems, especially Joint Compression. It is such compression contributing  to degenerative joint disease, leading to dysfunction, pain, suffering, and possibly surgery.

You also risk straining or even tearing tissues in the muscles, tendons and fascia. Sometimes these strains and tears happen at a microscopic level, and accumulate over time. … But lots of micros end up equaling a MACRO!

And if you are a Yoga Teacher, (meaning you are even MORE likely to hurt yourself) you might not be able to demonstrate certain, or any, yoga postures! … Not a Good Situation!

Yoga is Safer Than GOLF!

Now, it IS true. Yoga is, statistically speaking, SAFER than GOLF! But a funny thing about statistics: Even if it is only .035 percent (that’s only 3.5 practitioners out of 10,000!)* who get injured, if YOU are one of them, then for YOU, it is a 100 percent deal!

* Eva Norlyk Smith, Ph.D., writing at Huffington Post

Now, up until a few years ago, all this “injury stuff” was sort of a Deep, Dark Secret about how certain world-class yoga teachers, being taught by world-class gurus, were and are getting injured, sometimes severely. You can read more about that in my DSL e-Report on Yoga Injuries, but the story was broken open by William J. Broad in an article appearing in the New York Times …

Quoting from my e-Report:

Does Yoga “Wreck” The Body?

Now, this is an unfortunate way for yoga to end up in the news, but there are many ways one can injure themselves in physical yoga (AKA, postures or asana). And if the story wasn’t being talked about enough, the New York Times article in January of 2013,  broke the story wide open. The article was based on the book titled The Science of Yoga by William J. Broad. Right or wrong, it caused quite a stir in the yoga community.

And, according to the YogAlign.com website (created by Michaelle Edwards, LMT, ERYT) several very prominent yoga teachers suffered an apparent need for single or double hip replacements and other surgeries. …

Anyway, with millions of people doing yoga and millions more doing some form of stretching, it pays to know something about how these injuries happen, and how to prevent them. And, the same principles apply for a lot of different exercises and athletic activities.

A Discussion Of Psoas Muscle on Yoga International

On the Massage Forum on Facebook, a Group Member posted a link to an article on Yoga International discussing the psoas muscle. I had some comments on it.

QUOTE From Article on Psoas in Yoga International at:


A tight psoas can cause serious postural problems: when you stand up, it pulls the low back vertebrae forward and down toward the femur, often resulting in lordosis (overarching in the lumbar spine), which is a common cause of low back pain and stiffness; …"

This is, in my mind, one of the great Myth-Conceptions of Psoas muscle. Because it crosses the hip joint, it certainly does flex the hip joint, and draws the femur upward, and/or the spine downward. And most theorists assume that action tilts the pelvis forward (because all other things neutral or equal, hip flexion would by definition be an anterior pelvic tilt). And it's further assumed that anterior tilt of the pelvis also causes increased lordosis.
Now, take a look at the illustration below. (You'll have to click on it to make it bigger):

psoas muscle & lumbar attachments

Three Layers of Psoas and their affect on the lumbar spine & discs

Notice that the fibers of psoas are running almost vertical as they cross the vertebral bodies. When psoas contracts, it will pull almost straight downward, and only a little forward, on the vertebrae. Can you see how that will actually compress the vertebral stack, and compress or eventually crush the discs? That action is the OPPOSITE of lordosis. It is a kyphosis or flattening of the lumbar curve.

Also note this part of psoas has two layers. The anterior layer (blue) attaches to the vertebral bodies, and the posterior layer (red) attaches at the transverse processes. … Compression, distortion & facet syndrome anyone?

Looking deeper, literally, you'll see the green layer of psoas (well, it's not really green, at least I don't think so) — called the pars vertebralis — which is illustrated almost nowhere. Only place I've seen it is John Zahourek's Atlas of Anatomy. (He was the Anatomiken Guy, the 30 or so inch human anatomy models and clay making tools so we could learn anatomy better by making each muscle out of clay and putting it in its correct location. Jon retired from the company though.)Anyway, the pars vertebralis layer ONLY crosses the vertebral bodies, and does not travel down past L-5. It's only function is to draw the vertebral bodies together. (Well, there's another, which I'll get to below.)

NOW, when someone asks you why their discs are thinning or degenerating, or getting crushed, instead of saying "OH, you're just getting old," you can give them a REAL answer: their psoas has chronically over-shortened too much.I should also say all layers of psoas can work to restrict or control extension. So if a person is doing a deep, standing back bend, then psoas will eccentrically contract (gradually lengthen) to prevent the lumbar spine from traveling too far, too fast.OK, next, you can also see how the L-5/Sacral angle is so steep, the L-5 WILL be pulled forward and down, sliding L-5 forward off the angle of the sacrum. That's part of what creates the compressing & shearing action at L-5 / S-1 that is so common.At this point, depending on what else has been going on, the Client MIGHT have what I call a "pseudo-lordosis." But rather than a true lordosis, it is more like a "kinking" action at the posterior face of the L-5 / S-1 area, and sometimes including L-4. So when you look at someone, you might sees scoop in their lower back. But as far as actual lordosis goes, it is mostly, or totally, an illusion. Like the X-ray Dr. Koplen has in a different article here on the forum, if you draw a line through the center of the lumbar, it's a pretty straight line from T-12 to L-3. That means less lordosis, not more.


Pseudo-Lordosis & Lumbo Sacral Kink

(And you have to be very careful: many people have a big, deep scoop in their lower back REGION. But if you palpate their actual spine (spinous processes), their lumbar curve is either normal or they have a loss of curve in the actual vertebrae themselves. I've had one deeply curved there actually have a lumbar vertebrae actually slightly protruding posteriorly! She was under a HUGE amount of compression. 

This assessment error leads to a LOT of mis-evaluation of structure. I've had dozens of therapists in my trainings who were told by some guru somewhere they were an example of anterior tilt and excess lordosis. It did not take long for the class to see that was not true AT ALL. In other cases, they were pretty close to neutral.)

Now, the tricky question. Does the pelvis tilt anterior because of the lower part of psoas crossing the hip joint? Or does the pelvis tilt posterior (tucking under) because of the part crossing the lumbar spine? I'm tempted to say that they tend to cancel each other out and just compress everything right along the center line through the vertebrae and hip joint.

However, if the person is standing upright in gravity, their femur is much less likely to move much (meaning the psoas cannot lift their femur, unless they are going to stand on one leg, but in that case they are FAR more likely to posterior tilt anyway to stabilize against gravity). And the lumbar region will be freer to move because it is not holding the weight of the body or being stabilized by gravity as much. 

So my vote is it's more likely to go into posterior pelvic tilt. Please let me know what you think about all that.

On the other hand, a weak and overstretched psoas can contribute to a common postural problem in which the pelvis is pushed forward of the chest and knees."

I know this is blasphemy, but I do not consider psoas to be much of a postural muscle when just standing upright in gravity without extra weight or external forces. As mentioned above, psoas has better things to do than stabilize the spine unless you're doing some special movements or exerting or resting outside forces. (I don't buy the usual tent-pole model too much. And there are other muscles better positioned to do that postural stabilization job anyway.) 

Yes, psoas does eventually get recruited as such due to bad body mechanics and bad relationship to gravity. But there are so many other muscles that are hip & lumbar flexors, I doubt having an over-stretched psoas, by itself, would create the pushed forward pelvis very much, if at all. The other ones, like iliacus, adductor longus & brevis, pectineus, and rectus abdominus, will hold the pelvis back. What causes the pelvis to push forward has FAR more to do with over-shortened hip extensors: hamstrings, gluteals, and deep rotators.

OK, that's my short dissertation on Psoas. (I also have an 80-page version, too!) Feedback, criticisms, comments welcome. If you see anything wrong with my analysis, I'm happy to hear it because I want to improve my system of analysis where ever possible.

Is Yoga Injury A Real Problem?

Woman with Yoga Induced Back Pain?This is an unfortunate way for yoga to end up in the news, but there are many ways one can injure themselves in physical yoga (postures or asana). And if the story wasn't being talked about enough, the New York Times article last year, based on the book titled The Science of Yoga by William J. Broad, broke the story wide open. Please See the article on yoga injury in New York Times Magazine HERE.

I'll take a closer look at that article in another post soon, but Yoga injury statistics from many sources do indicate it's a far wider and deeper problem than most people realize. However, we must maintain a proper perspective on yoga injuries.

We'll talk about these and other article and book in another post on this website, but let's look at the realities here.

In my Private Practice of Yoga/Bodywork Therapeutics, I've worked with many people whom had a bad experience or two with yoga. As a result, some of them avoid yoga like it was a plague. Or even though they still love yoga, they've developed many aches & pains, limited range-of-motion, dysfunction, poor posture, and so on. They often resist the fact that yoga can and does cause such problems, if one doesn't know how to prevent them.

Yes, the author of  The Science of Yoga was absolutely correct, there ARE many yoga practitioners — even professionals — who've injured themselves while practicing yoga. Some of them are world class teachers who got to the point they could not even demonstrate a yoga posture without pain. A few of them ended up with injuries so severe they opted for surgery.

So, a yoga teacher getting a hip or knee replacement, or spinal fusion for a blown disc, is something to pay attention to, and think about. If THEY are having problems, what chance does a more casual practitioner have? (Actually, being a casual practitioner might save some people, if that means they don't practice very aggressively.)

But hopefully, if we learn something about how such problems can happen, maybe we can develop some strategies for prevention of yoga injuries along the way.

Delayed Feedback in Yoga

One of the Big Problems in yoga is that very often, when you do injure yourself, you won't even know it for hours, days, weeks or even months later. In fact, some people go for YEARS slowly "injuring" their body — in imperceptible, micro-amounts at a time — such that they don't feel their tension, stress and/or trauma building up in the background.

At some point, even though the actual percentage appears to be small, a significant number of people end up with injuries to their neck, shoulder, knees, upper of lower back … pretty much anywhere.

A complicating factor here is that up to a certain point, when a person is deep into a yoga posture (or asana in Sanskrit), they often feel GOOD. That's often because the stretch triggers neurotransmitters in their blood stream. If they stay within a certain range of intensity — which varies for everyone, and for each of us from day-to-day — they only experience a "good" feeling, or even pleasure. Some even report feelings of bliss coursing through their body.

Is Bliss A Good Thing?

Some people say, what's wrong with that? Well, often times, that pleasurable or blissful feeling is masking underlying sensations imperceptible to the conscious mind … sensations indicating over-stretching or even micro-damage to the muscles. In some cases, the student or teacher ends up going too deep for too long, and way too fast. The muscles cannot relax, release & lengthen quickly enough, potentially causing numerous problems in various body parts and systems.

As Joel Kramer, my primary yoga teacher, once said:

Bliss isn't everything it's cracked up to be.

Various people in the field of yoga have declared Joel to be The First American Yoga Master, and the Father of American Yoga. So, assuming they know something about yoga, we can learn a thing or two from him.

What Are The Primary & Common Causes of Yoga Injuries?

Dose "Proper Alignment" Help Prevent Yoga Injury?

Unfortunately, achieving and maintaining so-called Proper Alignment is NOT necessarily the solution. Sometimes, it is actually the cause of the problem in the first place. Here's why …

When the body will NOT go easily into a desired alignment within a posture or body position, it is most of the time because there's one or more muscles that are chronically contracted* and shortened up. They will not lengthen enough, or soon enough, to allow the body segment to move into the desired positioning. Resistance is generated if you start trying to push into it.

I call this chronic muscular contraction C.E.M.&.N.T. or Chronic, Excess Muscle & Nerve Tension. In fact, C.E.M.&.N.T. is the primary physical resistance to performing yoga postures or asana. Done in the spirit of integrative physical/mental yoga, C.E.M.&.N.T. becomes the meditative focus of the posture, rather than a barrier to overcome or push through. It is the NEXUS between body and mind, between one's psycho-neuro-musculo-fascial history and the many internal and external conditions of the present moment.

Please See My Pages on Chronic, Excess Muscle & Nerve Tension HERE

When we come up against that resistance, the tendency for many people is to try and push harder, to pull themselves deeper into the posture, rather than waiting for it to let go. Or better yet, use the resistance as a meditative focal point of self exploration to get deeper insight into the nature of that resistance, which is an expression or result of psycho-neuro-musculo-fascial tension.

This resistance sets off a number of reactions and problems we'll detail in another post, yet in turn has it's own background causes.

And of course, we must now discuss Yoga Injury Recovery.
