The document discusses different body postures. It notes that posture is not just a position but a dynamic pattern influenced by factors like gravity and anatomy. It identifies three types of posture: easy, rigid, and faulty. Easy posture provides good balance but cannot be maintained long-term, while rigid posture can be held for longer but places more load on joints and muscles. Faulty posture results in strained supporting structures from misaligned body parts and inadequate balance or curvature. The document emphasizes maintaining good posture during interviews by sitting up straight and avoiding closed body language.
