Postural deviations lead to improper joint wear, arthritis, muscle imbalances, disc degeneration, and often to metabolic disease. Not to mention how they physically affect the way you present yourself and the degree of confidence your body displays. Therefore, postural correction should be the primary focus in any activity. Whenever you feel any tension, fatigue, discomfort or even pain, the first thing you should always do is check in on your posture. Practice your sitting and movement posture as if your quality of life depends on it – because it certainly does!
Now let’s look at your seated posture. Notice the way you are sitting. Is the back curved, shoulders slumped, maybe even legs crossed? There is nothing novel here for people who spend the day staring at a computer screen.
• You will do less harm by sitting upright on the front edge of your chair with your knees slightly below the hips. Backrests tend to promote undue rounding of the spine and tend to push people into a forward-head-translation. The further forward your head goes, the shorter your hip flexors will remain, and that just leads to all sorts of mechanical problems.
• When sitting for a while, try to keep your chest bone (sternum) in front of your chin. As soon as the head starts to fall forward, your discs enter the compression/degeneration zone. Consider lengthening the distance between the rib cage and the pelvis when you stand. This will elongate your hip flexors.
