The best sitting posture is always the next
To sit dynamically, you need to balance your pelvis on your sitting bones. The spine is straight and the torso moves around the body’s natural sagittal line. Imagine the movement of the torso by picturing the motion of a roly-poly toy. You move your torso to the front or to the back from the hip, not by bending your spine.
Negative implications of sitting
The main problem with sitting is that the pelvis tends to tilt back during the transition from standing to sitting. Due to this pelvic rotation, the natural curve of our lumbar spine leads to an unhealthy “hunched posture”. From an ergonomic point of view, a balanced posture with a natural curve of the lower spine is best.
With your upper body raised, your arms can reach things better and your stomach has more space, meaning your inner organs are not compressed, which in turn helps you breathe deeply. A good office chair supports you in any position and follows every movement. It helps you to considerably reduce the strain on your spine.
How to sit down and stand up correctly
To keep the pelvis from tilting backwards when you sit down, pay attention to how you move and actively counteract the motion of your pelvis. (According to Kempf)
We spend too much time sitting
Even the best chair cannot change one fact: in the office, we spend too much time sitting. Seize any chance to get up – don’t sit for too long. Make a habit of taking short exercise breaks: walk a few steps to the copier or chat with your colleagues in person to flee from the unhealthy permanent sitting for a little while.
