Unless this is the first ever blog post of mine that you are reading you should be well aware that good posture both in standing and sitting is essential for neck and shoulder health.
If you are slouching your thoracic spine is hunched forwards, your neck is in a protracted position (head forward position) and then this leads to muscle imbalances and pain. In short, your chest muscles become too tight as do your frontal neck muscles and the opposing muscles become too long and weak. This leads to your shoulder blades rounding around your rib cage getting further away from each other at the spine. If you can imagine that the distance between your two shoulder blades should be about three inches apart from each other, well they literally drift apart making that space further as you keep hunching forwards at your computers, steering wheels, eating your breakfast etc.
What’s the problem with having my shoulder blades drifting apart?
So now you have your shoulder blades getting further away from each other which means the muscles that should hold them in their place are getting lengthened and weaker and the muscles in front of your chest are getting shorter and tighter (the opposing muscles). This is where things get messy for your shoulders. For a moment let’s forget about the problems slouching does to your muscles, ligaments and discs in your lower back and necks and let’s just keep focused on your shoulders themselves. If your back is now rounded making your chest too tight this also pulls your shoulder inwards. They are now rotated too far inwards(internally)! Now you are looking at a head on collision with your humerous (arm bone) mashing your rotator cuff tendons.
A quick test to see if your shoulders are rotated inwards
A very easy way to check is to stand with your arms at your sides. Now look down at your thumbs. Do they point forwards or point inwards at each other? They should be pointing towards the front. If they are pointing more towards each other, or worse, you are looking at the backs of your hands when standing there and your thumbs point sideways towards your midline, your shoulders are too tight and rotated inwards.
What to do to help your internally rotated shoulders
So now you know that your shoulders are inwardly(internally) rotated which means your chest muscles are too tight which means that your shoulder blades will more than likely have been pulled too far apart which means problems for your shoulders! At least 90% of shoulder problems will have problems with the shoulder blades, they are vital for good shoulder mechanics. So to help this problem we need to stretch the tight muscles and strengthen the weakened ones to get good balance again.
You need to start stretching out your chest muscles, both pectoralis major and minor and strengthening your middle back and shoulder external rotators. It makes sense really doesn’t it? Your shoulders are too far internally rotated which means that the internal rotators are too tight and shortened leaving your external rotators too long and weakened.
Therefore, stretch your pec. muscles and do the ‘I’ve got no money’ exercise.
The ‘I’ve got no money’ exercise
Here is a great exercise to strengthen the middle back and external rotators of the shoulder to get those shoulders working better again.
Stand upright with your arms by your sides and now bend your elbows with your palms face up as if you were about to carry a large tray. Have the insides of your elbows locked against your ribs. Stand tall and retract and depress your shoulder blades. In other words, before you start the exercise you want to contact your shoulder blades ‘down and back’. A nice way to think of this is imagine that you have a pencil between your shoulder blades that you want to keep in place with your shoulder blades. Make sure you are not shrugging your shoulder blades though! The motion is ‘down and back’ not ‘lifting up and back’. Now that you have put your shoulder blades in good position you start by rotating your hands away from each other to the sides but keep your elbows on your ribcage! Then return to where your palms are back in front of you again as if you are holding a tray.
Do this 6-8 times 3-4 times a day. Remember that once you have stretched your chest muscles and done this exercise you should then attempt to sit and stand in good posture throughout your day in everything that you do. Three minutes of exercises a day will do little to help you if you spend 10 hours a day of slouching at the computer!
