Sinking your Boat: (3) Practising Scuttling.

Practising.
Practising the art of sinking is essential; it’s not going to happen on its own.

When?
The good thing is that you can practise it all the time, whilst doing anything – lying down, standing, walking, cooking, sitting, gardening… etc.

Walking.
Walking is a very good way to practise it, the knack is not to try it every step you take.  At first try doing it with only one foot, or for example, every 4th step.

Practising boat scuttling.
Step forward, and as you put pressure on to the forward foot, sink your hull (your hip/pelvis), in particular into the same side as the stepping foot.  When you do this, it can feel a little as though you are lengthening the body.  The most important part is that you feel the hip and lower back settling into the foot.  As you do it, you might have a sensation of the crown rising gently, but this is not something to ‘try’ to achieve – if it happens, it happens.
In effect you are ‘lengthening your spine’ but with no intentional stretching.
This the Alexander Technique.

Sinking your Boat: (2) Above the Waterline.

Above the hull is the equipment that makes the sailing boat functional – mast & boom, shrouds & sails, sheets & cleats, and a burgee if you have one.
This is your upper torso.

But first of all…
When you sink your hull/keel, bear in mind that there is an upward pressure of the water.
As you now stand or sit, first of all let yourself sink (the hull), but then experience what the upward pressure of the water would feel like.
You might notice a lifting – almost a lightening – internally.  It’s this that makes the above-deck equipment able to function.  
If, however, you try to make this feeling happen, you will have stopped sinking the hull, and will have started to ‘do’, rather than ‘un-do’.

The rigging
The mast (spine) supports most of these bits of above-deck equipment – the shrouds (arms), the burgee (tiny head!), the sails, (torso – chest/back/rib cage); and the spreader (in the diagram) is a little like your shoulders running from port to starboard.  The boat in the picture even has trapezius muscles running upwards from the ends of the spreader to the top of the mast.

The mast
Your spine tries to sink to the bottom of the sea, but simultaneously it is pushing upwards to support the downwards pull of everything else (sails, rigging, boom, etc.).  If it isn’t strong enough, it will buckle or snap in the first wind that it encounters.  It needs to be strong enough to deal with the functions of all the other parts.

For the mast to be effective and efficient, the base of the mast needs to nestle into the hull of the boat. This is exactly the same as the relationship between your pelvis and your spine.

So whilst reading this, settle the base of your spine into your pelvis, noticing how the relationship between the two changes.
As you allow the water to ‘lift’ your hull, you may find that the spine alters shape, and that your head needs to readjust itself.

I Can’t Remember if I’m in Pain or Not.

Memory & the “Moment”.
The part of our brain that memorises events could never be said to be reliable; we remember the parts we want to remember (and even then those parts might be inaccurate), we give more importance to some memories than to others, and over time, even those can change – ‘bad’ memories taking on a rosy hue!
So with all of that going on, how do we “live in the moment”?

Pain.
In the case of pain, we know that something’s hurting (maybe physical, perhaps emotional), but to ‘get out of’ the pain-situation and back into the more comfortable-situation of which we have a vague memory, i.e. to relieve the problem, can be tricky.
So, our memories tell us that there’s an alternative, a preferable one that stems from the time before the pain.

Making ourselves healthily more uncomfortable.
Plenty of people take up yoga, Pilates, Feldenkrais, tai chi or qigong in an attempt to improve their health; this could simply be because they want to improve posture or coordination, have more energy, improve muscle-tone or balance, or perhaps it’s because they suffer from back pain, migraines, musculoskeletal disorders, arthritis, Parkinson’s, or any other number of reasons.
My interest in this is that, by trying to better our health, we often unintentionally bring pain or discomfort on ourselves; having done that, we then want to get back to the same state of comfort we were in before we began the new health regime, but at the same time, we want to keep the newfound health that we may (or may not) have acquired.

Hoping for the best.
At the start of this term, two people came to try out a class, both suffering from different problems – one from recurring migraines, and the other from ME.
As usual, I warned both of them to take things very easily, to sit down as often as they wanted, not to push themselves, and that there was no competition involved – in short, to only do as much as they were able.
The next day I received emails from both; one had a sore neck (the person who suffers from migraines), and the other had a hip that was uncomfortable.  Both won’t be returning.

If it sounds as though I’m moaning about this, I’m not – the choice was, and is, entirely theirs; I know that I did everything possible to make their experience a positive one.
However, what I do know is that, as soon as you start to try to change stuff about yourself, to ‘improve’ yourself, or to take control of your health, things change, and change can often be uncomfortable, and can happen in parts of you that you didn’t anticipate.

The Comfort Zone.
Our ‘comfort zone’ is where we are at ease with our situation and environment, it could even be uncomfortable (comparatively).  Most people try to live in this ‘comfort zone’, hoping that things will stay as they are for as long as possible, whilst at the same time waiting for the (perhaps) inevitable change which they feel to be out of their control.

So, how DO you do something about it?
If you currently have pain somewhere that, as far as you know, has arrived out of nowhere, how do you relieve it (without using painkillers)?  One moment everything was fine (comparatively again), and the next it wasn’t.
Nearly everyone wants to get rid of that pain, but as soon as you try to feel your body back to its previous state you’re definitely not ‘living in the moment’… you’re trying to bring back what you think you’ve lost – attempting to go back in time.
Isn’t this the fear of the loss of the ‘comfort zone’ – the fear being that it will never return?  In your memory, how your situation or environment used to be was a lot better than how it currently is.

Falling into the old habits.
As an example, I have recently had a pain in my upper back somewhere between T2 & T4.  I wasn’t entirely sure why it started, and because it was tiring I wanted nothing to do with it.
So I tried all the usual things: I ignored it, I tried gently stretching it, I breathed into it, I put heat on it, I practiced a lot of Alexander Technique, I took it for a steam & sauna, I focused on consciously relaxing it during everyday actions (walking, sitting, etc.), – all to no avail.
Finally the penny dropped and I realised that, because of a number of changes that I’d been working on recently (postural etc.), other things were bound to alter.  It then started to get better… and I realised that this had finally happened because I’d accepted it and thereby brought it into the present – I’d allowed it to be, rather than trying to change it.

Standing Qigong and ‘Balance’

The Position.
There are many positions In which to do Standing Qigong, but I’ll use the one with feet a shoulder’s width apart, knees bent, and hands lifted to opposite the upper chest, as in the picture.

What does ‘balance’ mean in this context?
In this context, balance means the sense of the left and right sides, the front and the back, and the top and bottom sides of your body all working equally together, so that no area is more dominant than any other area.  It is the feeling that a balloon might have (if a balloon were able to feel) both on its skin, as well as internally (equal pressure to all parts of itself).

Feeling the position – the concept.
When you squeeze a balloon, two forces come into play – an inward and an outward force.
1) The pressure that your arms exert inwards, so that you don’t drop the object, and …
2) The pressure inside the object which pushes your arms outwards.
A balance is therefore achieved.  In other words, in Standing Qigong positions, you are being expanded whilst at the same time holding on.

The legs.
Hold the legs as though you have a ball between thighs and knees.
As above, this is a two-way sensation; you feel an outward expansion (as though the ball were pushing your knees apart), but at the same time, because you don’t want to drop the ball, you squeeze inwards.
If you get the idea for the legs, the rest will be easy to follow.

The arms (1).
The arms use the same idea.
The ball is between the elbows/upper arms and the front-sides of the torso (in other words, it’s not exactly the sides, nor is it the front… it’s what you might call the anterior-lateral aspect of the body).  Again, the same principle applies – the ball is pushing your arms/elbows away from your body, but simultaneously you don’t want to drop it.

The arms (2).
Feel as though there’s a ball within the circle of your arms.  It expands your arms, but you don’t want to drop it.

The arms (3).
Feel as though there’s a ball outside the arms and around your back.  Your back and arms expand, but simultaneously compress inwards.

The legs & pelvis.
Your knees are bent; you are sitting on a ball.   The ball is pushing your knees forwards (which lowers the buttocks), yet at the same time you want the buttocks to be lifted by the ball.  This is similar to how it would feel if you were to attempt to push an aerobics ball into e.g. a swimming pool; whilst you push down, the surface tension would be pushing up against the ball.

The fingers.
This is exactly the same principle as above.

Other applications.
You can apply this concept in many other ways:
The same idea between the toes as between the fingers.
Ditto from the backs of hands/outsides of arms to the back.
Ditto feet to head.

The Neck – The Master of Counterbalance.

Your neck controls your future comfort.
It’s never too late to do something about your posture, although it’s probably true to say that the earlier you start, the more comfortable your later years will be.

The ‘Seesaw Law’.
In some respects, your spine works like a seesaw; if you do something to one end, there will be a reaction not only at the other end, but across the entire length of the seesaw.  In other words, if you position your neck incorrectly on your body, you are automatically setting up a series of detrimental chain reactions.

An adult head weighs something in the region of 11-12lbs (5-5½Kgs).
When balanced correctly on your body, the line of gravity passes straight through the middle of the body to the supporting feet.  So, when you incorrectly position it forward of that line, the neck is forced to take extra strain as the head moves further forwards.

The musculature in the body doesn’t like this, and will automatically try to find the most comfortable position.
Therefore, following the Seesaw Law, it will make a number of ‘better-than-doing-nothing’ adjustments; in other words, it sets up a series of counter-balances, the objective being to try to make the situation as comfortable as possible.

With these in place, you might not be 100% comfortable, but at least you can function as long as you don’t do anything extreme with your body.

The 21st Century Person.
One of our main activities which encourages both back & neck problems, and helps us to develop a permanently poor posture is the way that most of us use our mobile phones.  This can easily become a ‘habit’.

A few pictures say it all:

                                   

The ideal phone posture to save your neck.
This photo is one way of demonstrating the best position to hold the mobile phone.  You have to lift the phone high enough to look over the other person’s shoulder, and the body is upright.  (It doesn’t take into account a font that is too small, which makes us tighten the neck, perhaps pulling it forward also).

Unfortunately, one of the downsides of using the phone whilst draped around someone else is that walking becomes slightly impractical…

What do YOU do with your neck?

How is it at the moment?
How do you position your neck?
How does it sit on your body?
How does it control you?
How does it affect your comfort or discomfort levels?

Where does your neck begin and end?
Anatomically your neck is 7 vertebrae long, starting at the skull (under and up inside), and finishing at the slightly more protrusive vertebra C7 (the 7th cervical vertebra) which is at the base of the neck, above shoulder line height.

 

To be honest, I’m not actually very interested in its anatomical length, I’m much more interested in its functional length.
Functionally it finishes around about T3 (i.e. the 3rd thoracic vertebra) which is slightly further down the back, although this can be slightly lower for some people.

So what?
You might think, “So what? How does that make any  difference?”
Functionally, it makes a massive difference, because the place from where you control the movement of your neck alters dramatically, which in turn affects how you position your both your head and your spine.
Amongst other things, this affects your posture, your breathing, and how relaxed you are.

Dropping your head.
Usually when we drop our chins we think of the pivotal or ‘folding’ point as being roughly at shoulder height. As a result, when just balancing the head on the body (without lifting, lowering, or turning it), we feel as though that point of balance is roughly at C7. However, if you balance it from further down, it very much alters how and where you place your head on your body.

Think lower.
If you visualise your neck finishing lower (e.g. T3, further down your back), all of a sudden it starts to straighten, the connection point (between T3 and T4) softens and sinks slightly, and your neck actually moves backwards on its own accord.  In Alexander Technique terms, it would be described as your spine ‘lengthening’.  (AT also refers to this as ‘forward & upwards’ – I think that the ‘forward’ is slightly confusing as it implies pushing your face forward, but what actually happens is that the head rotates on the Atlas (see top diag.) and whilst the forehead moves slightly forward, the chin tucks slightly under).

Potting plants.
Positioning your upper spine correctly is not unlike pushing a stick into soil in order to support a plant (your head, in this case); if you put the stick in shallowly, there’s a good chance that it will lean over with the weight of the plant.  A stick planted deeper will be much more supportive.

Anatomically (briefly).
The reality is that you are not really relaxing your actual spine, … how can you when it’s made of bone?  You are actually softening the tissues on the anterior aspect of the spine – the side nearest your chest, at the back of the lungs, as well as the supporting muscles around the spine in this area.

Another way to think it.
When either sitting or standing, if you imagine that there is a ‘mouth’ on your upper back, and you are very, very gently putting the lips of the mouth together (you need to feel as though this is actually happening), in particular by dropping the upper lip on to the lower lip, you might feel your posture altering as the spine changes position.

And the result is …
When you allow this to happen, your back relaxes and sinks, your chest appears to lift, your shoulders feel as though they are rolling backwards, the collar bones seem to settle back, the upper arms sink into the correct area of the shoulder socket, and your breathing deepens as the ribs find their optimal position.  Additionally your balance is altered for the better, there is a sense of being connected to the ground (gravity can now pass directly through you), and the body is able to move with greater ease.

Addendum for those who can feel this.
As you position your spine, simultaneously soften the inside of the breast bone (sternum), and allow the armpits to deepen.
Why?
If you picture the upper chest (the upper part of the lungs) as being an inverted bowl, by observing only the spine, you are really only dealing with the back of the bowl.  By working on the front and sides of the bowl (inside sternum & inside armpits) you balance the front, back, and sides of the upper chest cavity which roots the neck even better.

I’ve Got That Sinking Feeling.

Feeling that sinking feeling.
If you’ve ever been at the seaside and put your foot on a raised rock, and then attempted to push yourself up using only the leg on the rock, you’ve had the sinking feeling.  Your leg briefly works very hard, and it feels as though your torso is compressing your leg and foot into the rock.

But of course this could be almost any action in which you have to lift your body – it could even be walking up one small step on the stairs; but you actually do the same thing even when walking on the level.  When you put that foot forwards and move the weight on to it, for a brief moment the torso sinks into that solo leg before pushing itself upwards in order to bring the other leg through for the next step.

So what’s going on?
The Chinese wrould say that you are sinking your qi during that moment, and for some people, it’s not a very pleasant sensation.  I’ve noticed that, by and large, people don’t like the feeling of their legs working correctly.

One of the reasons tai chi teachers spend so much time correcting people’s postures is that, when we need to do something with our legs that requires effort, instead of just using our legs, we ‘borrow’ other muscles, (‘recruit’ in Alexander Technique terms), in the hips, back, and even the neck that aren’t necessary for the job.
Why?  Because it’s easier on the legs; it spreads the load.  It’s fine occasionally, but the trouble is that it rarely is occasionally … it becomes a habit.

This becomes apparent when, for example, I correct someone’s posture in Stork/White Crane Spreads its Wings, (where all the weight is taken on one bent leg).  People usually find it very difficult, even unpleasant; they don’t like the feeling of only the necessary muscles working correctly.

Passing the 40 mark.
These problems gradually become more extreme as we age.
There may be very good reasons for this, such as arthritis, worn joints in knees, hips, and ankles, debris in the joints, joints that have changed shape through misuse over time, cartilage problems, etc., but leaving these mechanical reasons aside, most people as they age don’t trust their joints as much as they used to when they were younger, mainly because they haven’t strengthened those particular connections over time, and little by little have ended up sitting down more.

Or even younger.
Leg strength used not to be a problem for people in their 20s and 30s, but over the last 10 years I’ve noticed that it’s definitely edging into these age groups.
I’m guessing that it’s partly to do with our lifestyle, including both what we eat and how much, but also screens of all types (we don’t even have to walk to the phone nowadays, it’s often in our pocket), and that so many jobs are sedentary.

I’d rather use a coat hook.
Older people often appear to be trying to ‘hold themselves up’ off the ground.  Their qi, instead of sinking, seems to be held more and more in the upper body, as though they’re trying to take the weight off their legs.  In a sense that’s exactly what they’re trying to do, because if you don’t trust your hips or knees, you’re not sure if your knees are going to give way, you’re worried about exerting pressure on the wrong part of the knee, or you’re worried about your balance, then that’s exactly what you’d want to do.
It’s a vicious circle; the less you use your legs, the less you trust them, and therefore the less you use them, etc.

And the point is?
Well, obviously… You’re doing the right thing if you’re doing tai chi or qigong.
There’s plenty of research available about how they can benefit all the joints, and even doctors, who 10 years ago knew nothing about tai chi and qigong, are now recommending that joint sufferers, and people with balance problems (and heart/blood pressure problems) take them up.
Perhaps we should all be taking deportment classes!

Heavy Arms

Each of your arms weighs about 8-10lbs (roughly 3.5-4.5Kg).
That’s heavy… though we don’t really notice it because either the arms are hanging down beside you, or, if we do come to lift them, we use so many extra and unnecessary muscles to do the job (known as ‘recruiting’ in the Alexander Technique) that their weight is spread across the shoulders and neck.

Where’s the qi?
The result of this is that the qi is held in the upper body which means that
     • our balance compromised,
     • our breathing tends to be higher,
     • our ability to relax is diminished,
     • the flexibility of our necks and is reduced,
     • we’re more inclined to get headaches,
     • the rotational potential of our waist becomes less,
     • the range of movement in both shoulders and arms is massively impacted.

It’s all about the shoulders really.
The idea is to lift up your arms, forwards or sideways, and attempt to experience the weight of your arms. What this actually means is that, in order to get that feeling, you can only use the essential muscles. This will also mean that you will need to disengage the shoulders from the task; they aren’t necessary.

Weighing a fish.
The muscles that you use to do this should feel as though they are weighing a fish with one of those spring-loaded hanging scales (I guess that could be your hand luggage also, but the fish is a bit more interesting!).  You have to give the arms to gravity, letting go of the muscles so that they gently stretch. If you’re not used to this, it can make them ache as they undo, but it doesn’t last.

Now just do it for the rest of your life!
That’s how to use your arms in tai chi and qigong, but the concept should also be applied to every activity, whether cooking, reading a book, or driving your car, etc., in fact every time you start to raise your arms from the vertical hanging position.

The Fly & The Bay Window, or Relaxation & Perspective

The headache.Headache
I awoke with a headache a few months ago.  Still lying in bed, I tried to relax the area where I could feel the tension stemming from.

… Partial success.

The fly.
A few days later, I noticed a fly in the room which kept on attempting to get through the middle of the three windows in the bay – which was closed.  The windows at the sides were both open, but it was repeatedly attempting to crash dive the closed one; even though a fly has virtually 360 degree vision, it seemed to have tunnel vision.

fly-angles-2Perspective.
It occurred to me that my headache was also a matter of perspective, and like the fly, I wasn’t taking the over-all view, I was focusing too specifically.

Since then, I’ve had a couple of minor wake up headaches, usually coming from my upper back, and each time I’ve tried the ‘perspective relaxation’ technique, for want of a better name.fly-angles-1

What I should have done.
I put myself into the position of what the fly should have done to achieve its intention.  This was like standing outside yourself, and, with that overview, I was then able to relax a much wider area than just the specific point of pain.
This noticeably reduced the discomfort, as though, by releasing the periphery of the pain, it reduced the core.

Stand outside yourself.
This perspective is like standing 1 or 2 feet outside yourself.  It doesn’t  work if you try to feel and judge the results at the same time.  You need to ‘get outside yourself’, and attempting simultaneously to feel the results only brings you back inside yourself to the place where you experience the discomfort.

Taiji, Qigong, and The Alexander Technique.
If you’ve tried Alexander Technique lessons, you will know about taking in the whole picture as this is the basis of lengthening and widening, and fundamental to the concept of release, or ‘not holding on’.
This ‘openness’ is also fundamental to the movement of energy in tai chi and qigong.

Widening your perspective so that you see your body moving as a whole, and relaxation will ensure that your tai chi & qigong movements, instead of feeling clumsy, off-balance and heavy, will feel loose, coordinated, and flowing.

How to Brush your Teeth/Hair (aka lifting your arm).

Don’t think about it…  Try lifting your arm sideways.

‘Recruiting’
Almost everyone will have involved both the shoulder & neck.  Alexander Technique calls this ‘recruiting’ muscles – you are borrowing muscles which you don’t really need to do the job.

To lift your arm out sideways you actually only need 3 muscles:-

  • Diagram 1: the Supraspinatus
  • Diagram 2: the Deltoid (lateral fibres)
  • Diagram 3: the Serratus Anterior

Supraspinatus 1Deltoid 1Serratus Anterior 2

The Supraspinatus starts the sideways lift, maybe the first 30 degrees; the Deltoid then takes over until the arm is parallel to the floor. The final lift to the vertical is done by the Serratus Anterior.

Trapezius 2What most people do.
But most people use the Trapezius which has its origin in the neck at the mastoid process at the base of the skull.

So if you want to lift your shoulder this is a great muscle to use, but using it to lift the arms sideways or even forwards is a waste of energy.
The trouble is that we get used to it, and the ‘correct’ muscles don’t develop properly.

What does correctly lifting the arm sideways feel like?
If you put the middle of your palm on the angle of the opposite shoulder (where the arm joins the shoulder), and then lift the hand/arm sideways, you should feel a ‘hollow’ appear in the shoulder underneath your palm, as though the shoulder is sinking away from the palm.  It should almost feel like a set of old-fashioned scales – the arm goes up, the shoulder goes down, and the ‘hollow’ deepens.
If you don’t feel this, there’s a fairly good chance that you’ve engaged a few extra muscles to do the job.

Arm lift 'hollow'The ‘hollow’; what forms it?Deltoid & Acromium (posterior)1
The slightly worrying picture on the left shows the ‘hollow’ that forms when you lift the arm sideways (abduct it).
The middle fibres of the deltoid (the lateral deltoid) are attached to the ‘Acromium‘ – which is the end of your shoulder-blade.
So when you abduct the arm, after the supraspinatus has done the initial 30 degrees or so of lift, the middle portion of the deltoid takes over.

Deltoid & Acromium 2 The 3 portions of the deltoid, front (‘anterior’ above in red), middle (‘lateral’ above in green), and rear (‘posterior’ above in blue) are in a horse-shoe shape, as shown in the diagram on the left.Shoulder muscles
On lifting the arm beyond parallel to the floor, you start to feel the middle of that horse-shoe.

BUT, you don’t if the Trapezius, which lies on top of the shoulder, hasn’t relaxed.

And the final part of the lift to vertical.
Easy, you can feel this yourself.  Put your opposite hand on the muscle – on your ribs, at the Serratus Anterior 5side of your body, below your arm.  When you lift the arm from 90 degrees to 180 degrees, you can feel something going on under your hand.

The muscle is tightening and pulling the lower corner of the shoulder-blade as if to pull it under your arm.  This makes the final lift as it makes the acromium, which is part of the shoulder-blade, rotate further upwards.

Brushing your teeth/hair?
There are so many daily activities that we do where we keep reinforcing the incorrect use of certain muscles, and brushing your teeth is just one of them.
To the list you can add – brushing your hair, drinking, pointing at something … in fact, any action where we lift the hand as high as, or higher than the shoulder (and sometimes not even that high).

Teeth brush 1 Teeth brush 2

All you have to do is to spot when you do it!
