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.
One of the beauties of the Functional Movement Screen is that the screen allows us to distinguish between issues of
stability and issues of
mobility.
Cook's thoughts were simple and led me to realize that the future of
training and of corrective exercise may be on a joint-by-joint approach
rather than a movement-based approach. 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. 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.
We
may not have understood the difference between mobility and stability
as it related to the ankle, but we did know that squatting in work
boots allowed us to get depth easier. In simple terms, heeled shoes
(work boots in this case) compensate for poor ankle mobility. So the
take home lesson is work on ankle mobility if you have depth issues in
the squat. 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) Looking
at the body on a joint-by-joint basis beginning with the ankle, this
thought process seems to make sense. In jumping sports an immobile
ankle causes the stress of landing to be transferred to the joint
above: the knee. 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.
Perform
an overhead squat. If the arms fall forward (technically, the arms can
fall forward but must stay in line with the trunk angle), then add a
heel lift. 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?
If
you feel a big stretch, you have a flexibility issue and calf
stretching will help. If you feel "stuck" or a pinch, you have a
mobility issue. Flexibility issues are cured by stretching, mobility
issues are cured or cleared by mobilizing the joint. If you think
there's no difference, you need a little more studying
The Knee (Stability) The
knee itself is simple and straight-forward. Knees need stability. They
are hinges with minimal rotary components. Think squats and straight
leg deadlifts. Old school. Call it anterior chain and posterior chain
if you want, but it's not complicated.
The
key problem in training the knee is that the back gets compromised due
to lack of hip mobility. Here's where it gets interesting. Squats and
deadlifts may be great exercises, but if you load an athlete who has
poor ankle or hip mobility, you risk damage to the low back. 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) The exception to our mobility/ stability rule seems to be at the hip. My friend Jason Ferrugia (www.j1strength.com ) has been ranting about hip mobility lately. Jason thinks all hip mobility work is a waste of time. 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.
Jason
writes that mobility and flexibility were synonyms. In reality, they
aren't. Flexibility applies to muscles and is indicative of length.
Mobility applies to joints and is used to describe motion. 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.
