Chapter. 3 Changing your Work Posture

5 Work Postures Recommended by Okamura

It is important to change your posture to best suit the task at hand.

Writing a report, working on a computer, doing presentations in a meeting, talking on the phone…

There are various tasks performed in the office. To keep the ideal posture in each situation, Okamura recommends five different postures. However, even the most ideal posture can only be maintained for approximately 30 minutes. In order to eliminate strain on your body, try to make a shift from one posture to the other, alternate between sitting and standing, take a break, and make use of a chair and a desk, or support apparatus.
