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:-

  1. Diagram 1: the Supraspinatus

  2. Diagram 2: the Deltoid (lateral fibres)

  3. Diagram 3: the Serratus Anterior


Supraspinatus 1

Serratus 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 2

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.

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 5

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).
