My good friend, Physical Therapist Gray Cook, has a gift for simplifying complex topics. I envy his ability to succinctly take a complicated thought process and make the idea appear simple. In a recent conversation about the effect of training on the body, Cook displayed one of the most lucid thought processes I'vc ever heard.
Gray and I were discussing the findings from his Functional Movement Screen evaluation system. (www.functionalmovement.com). For those who are unfamiliar, the Functional Movement Screen is a system used to evaluate the mobility and stability of the body.
If you train athletes other than yourself, I'd strongly recommend you visit the site and familiarize yourself with the screen. The tests can help to identify the needs of the different joints of the body and how the function of the joints relates to the execution of the lifts.
Cook's analysis of the body was a straightforward one. In his mind, the body is just a stack of joints. Each joint or series of joints has a specific function and is prone to specific, predictable levels of dysfunction. As a result, each joint has specific training needs. The table below looks at the body on a joint-by-joint basis from the bottom up:
Joint Primary Training Needs
Ankle mobility (particularly sagittal)
Knee stability
Hip mobility (multi-planar)
Lumbar Spine stability
T-Spine mobility
Gleno-humeral stability
The first thing you should notice as you read the above table is the joints simply alternate between the need for mobility and stability as we move up the chain. The ankle needs increased mobility, and the knee needs increased stability.Ankle mobility (particularly sagittal)
Knee stability
Hip mobility (multi-planar)
Lumbar Spine stability
T-Spine mobility
Gleno-humeral stability
As we move up the body, it becomes apparent that the hip needs mobility. And so the process goes up the chain: a simple, alternating series of joints.
You're probably asking yourself, "What does this have to do with lifting?" Can it make me squat more? Yes, absolutely.
The basic fact is that over the past twenty years the average gym-goer has progressed from the bodybuilding approach of training by body part to a potentially more intelligent approach of training by movement pattern.
In fact, in the sports world, the phrase "movements not muscles," has almost become an overused one and, frankly, that's progress. I think most good lifters have given up on the old chest-shoulder-triceps muscle mag thought process and moved forward to a push-pull-anterior chain- posterior chain thought process.
I think the injuries we see and technical problems we encounter with many lifters relate closely to proper joint function or more appropriately to joint dysfunction. Confused? Let me try to explain. In simplest terms, problems at one joint usually show themselves as pain or a problem in the joint above or below.
The simplest illustration is in the squat. As a former Powerlifter, we know that the big issue in the squat is depth. If you had trouble getting deep, the first thing the old school gurus did was recommend that you elevate the heels.
How many people do you know who can no longer squat due to back pain. My theory of the cause? Loss of hip mobility.
Loss of function in the joint below (in the case of the low back, the hip) seems to affect the joint or joints above (lumbar spine). In other words, if the hip can't move, the lumbar spine will.
The problem is that the hip is built for mobility, and the lumbar spine is built for stability. When the supposedly mobile joint (in this case the hip) becomes immobile, the stable joint ( the lumbar spine or lumboscaral joint) is forced to move as compensation, becoming less stable and subsequently painful. In other words, if you lack hip mobility or ankle mobility, you'll lean forward in the squat and shift stress to the back.
The process is simple:
• Lose ankle mobility, get knee pain.
• Lose hip mobility, get low back pain.
• Lose thoracic mobility, get neck and shoulder pain (or low back pain).
The Ankle (Mobility)
In fact, I think there's a direct correlation between the stiffness of the basketball shoe and the amount of taping and bracing that correlates with the high incidence of patella-femoral syndromes in basketball players and other frequent jumpers. (ADD Anterior Knee Pain Link)
Our desire to protect the potentially unstable ankle comes with a high cost. We've found many of our athletes with knee pain have corresponding ankle mobility issues. Many times this follows an ankle sprain and subsequent bracing and taping.
In lifting, as we noted above, poor ankle mobility results in a need to lean into the squat and attempt to use the hip extensors to a greater degree. You can tell if you have an ankle mobility issue by taking the FMS Overhead Squat Test.
If the heel lift solves the problem, the problem is primarily in the ankle. How do you know it's a mobility issue versus a flexibility issue? Take a simple test. Assume a calf stretch position. Do you feel a huge stretch or a do you feel "stuck" in front?
The Knee (Stability)
We come back to the same idea. Most back pain is not a result of a bad back, but rather the result of poor hip or ankle mobility. The back is more or less the victim. My philosophy to cure a bad back is to, in the words of back expert Stuart McGill, "spare the spine."
McGill, in both his books (www.michaelboyle.biz/joomla/content/view/72/53/ ), emphasizes that most back pain sufferers don't have a weak back. In fact McGill's research is very clear. Those with a bad back generally have stronger back extensors than those with a weak back.
Yes, that's what I said and more importantly, what McGill states in all his writings and lectures. Back pain is not about a weak back. Back pain is about overuse, primarily from flexion forces. Guess what. Heavy squats and deadlifts produce flexion forces. Look at the research on my website under McBride research.
The Hip (Mobility)
I wrote to him and disagreed. In fact, I think in strength development hip mobility is key. As I stated above, good hip mobility allows us to use multi-joint exercises to strengthen the lower body.
To be honest, the hip is incredibly complicated and merits great attention. I wrote an entire article on Understanding Hip Flexion (www.michaelboyle.biz/joomla/content/view/21/34/) and am working on one on Understanding Adduction.
The hip, much like its upper body counterpart, the shoulder, can be simultaneously immobile and unstable; immobile because of lack of flexibility and lack of motion, and unstable due to weakness, too much reliance on double leg strength exercises, or too much reliance on machine based training.
The result can be knee pain from the instability (a weak hip will allow internal rotation and adduction of the femur) or back pain from the immobility and accompanying forward lean. How a joint can be both immobile and unstable is the interesting question.
Both weakness and/ or immobility of the hip in either flexion or extension causes a corresponding compensatory action at the lumbar spine. This is the problem in squatting. In our joint above/ joint below concept, the lack of hip motion compromises the low back in squatting.
As the spine moves to compensate for the lack of strength and mobility of the hip, the hip loses more mobility. It appears that lack of strength at the hip leads to immobility, and immobility in turn leads to compensatory motion at the spine. The end result is a kind of conundrum: a joint that needs both strength and mobility in multiple planes.
Let's look further at the interrelationships. The weakness of the hip in preventing adduction causes stress at the knee. We've oversimplified this to a glute medius weakness, however the weakness often extends to the glute max and the hip rotator group.
In this case we need frontal plane control to prevent patella femoral problems, IT band issues, etc. In the sagittal plane, poor psoas and iliacus strength and/or activation will cause a pattern of lumbar flexion as a substitute for hip flexion.
Poor strength and/or activation of the glutes will cause a compensatory extension pattern of the lumbar spine that attempts to replace the motion of hip extension. In other words, if you can't move your knee up (i.e flex the hip), you'll flex the lumbar spine to achieve a motion that appears similar.
The Lumbar Spine (Stability)
In other words folks, you don't need to stretch your low back. Trust me, I know what you're going to say. "It feels good to rotate." It does feel good when I do that stretch. Check out my article, Is Rotation Even a Good Idea? (link to Is Rotation Even A Good Idea?) on my site.
Do you know what I tell coaches and trainers when they tell me "it feels good when I do X," I tell them scratching a scab on a cut also feels good. However, the result is bleeding and scar formation.
This is how I feel about rotational stretches for the low back. They're like scratching a scab. I believe that most if not all of the many rotary exercises done for the lumbar spine were misdirected. Both Sahrmann (Diagnosis and Treatment of Movement Impairment Syndromes) and Porterfield and DeRosa (Mechanical Low Back Pain: Perspectives in Functional Anatomy) indicate that attempting to increase lumbar spine ROM isn't recommended and potentially dangerous.
I believe our lack of understanding of thoracic mobility has caused us to try to gain lumbar rotary ROM and this is a huge mistake. So let's get back to lifting.
The lesson here is, never, and I mean never use any kind of rotary torso machine. Eliminate all the trunk twists, Scorpions, etc. that you do to "warm-up" your low back. As McGill says, "Spare the spine."
All this talk over the past ten years has been about core stability, not core mobility. The lumbar spine needs to be stable, not mobile. Squat tall with the bar high; deadlift with a flat back. If you have a history of low back pain, go single leg.
Thoracic Spine (Mobility)
The approach seems to be "we know you need it, but we're not sure how to get it." I think over the next few years we'll see an increase in exercises designed to increase thoracic mobility. Interestingly enough in SAHRMAN Diagnosis and Treatment of Movement Impairment Syndromes, physical therapist Shirley Sahrmann advocated the development of thoracic mobility and the limitation of lumbar mobility.
We've added a simple thoracic spine mobility drill to our warm-up to try to get the thoracic vertebrae to regain lost motion.
The Scapulo-Thoracic Joint (Stability)
Logic dictates that this is a joint that needs stability. As a lifter, this is the key to the health of the rotator cuff. As we all know, our fascination with supine pressing has made rotator cuff tendonitis almost a badge of honor in the lifting world.
Charles Poliquin has frequently talked about lower trapezius strength and its relationship to shoulder health. Bottom line. The scapulo-thoracic joint is usually weak and under worked. Most strength athletes don't do nearly enough back work and, rarely do mid-back work like rows.
If they do row, they like the bent row, which often compromises the lumbar spine as it attempts to work the scapula stabilizers. Most, if not all, lifters need more rows for the scapulo-thoracic joint as well as isolated exercises for the scapula-thoracic joint.
Low trap raises as well as exercises that have become know as Y's, T's, W's, and L's or U's all directly target the scapula stabilizers
My next question. Why does your incredible size allow you to bench? That's when they usually just shut up and acknowledge their weakness. Work to stabilize the scapula and at the same time, to develop the strength of the retractors like the rhomboids and lower traps. Just because you can't see them in the mirror doesn't mean they're not important.
The Shoulder
The shoulder is a complex system in that the gleno-humeral joint is strongly interrelated with the scapulo-thoracic joint. I like the "You can't shoot a cannon from a canoe" analogy here.
The scapulo-thoracic joint is the stable base that allows a mobile shoulder to work. We need to be able to lock the shoulders in place in a retracted and depressed position with the scapula stabilizers for the gleno-humeral joint to function properly.
The bottom line is that a stable shoulder complex will make for a healthy shoulder complex. The best exercise to feed this interrelationship is what we call Wall Slides. Wall slides can best be described as an active range of motion exercise for the gleno-humeral joint, combined with a stability exercise for the scapulo-thoracic joint.
Many beginners will actually cramp in the lower trap/ rhomboid area as they attempt this exercise. The key is that the forearms must slide up in contact with the wall while the shoulder blades stay down and back.
Don't be surprised if you can't do it. It'll take some time. Only lift the arms overhead as far as pain free ROM allows. Initially this may be a small range, but trust me, it'll improve.
From a lifter's standpoint, the important take-away is that good shoulder health is all about what you can't see. I think most lifters should stay away from heavy overhead work until they master the wall slide.
I also think the need for a combination of stability and mobility in the gleno-humeral joint presents a great case for exercises like Stability Ball and BOSU Push-ups as well as unilateral dumbbell work.
The inability of joints to function normally places stress on the joints above or below. In the book Ultra Prevention (actually a great nutrition book, too), the authors describe our current method of reaction to injury perfectly. Their analogy is simple; our response to injury is like hearing the smoke detector go off and running to pull out the battery.
The pain, like the sound, is a warning of some other problem. Icing a sore knee without examining the ankle or hip is like pulling the battery out of the smoke detector.
What we need to realize is that "We get old too soon and smart too late." Oscar Wilde said, "I am not young enough to know everything."
Every day, I learn more and more about the body. What I learn allows me to be a better coach and a better educator. Often, what I learn contradicts what I formerly believed. Just remember, the world was once thought to be flat.
