The document discusses body stillness, symmetrical and asymmetrical body shapes, and proper posture when standing and sitting. Body stillness can be demonstrated through gymnastic stunts that hold momentary still poses. Symmetrical shapes have identical forms on both sides showing balance, while asymmetrical shapes have two different forms showing uneven balance. The proper way to stand involves holding your head up, shoulders back, tummy tucked in, knees straight, and chest forward. The proper way to sit keeps the back straight against the backrest, knee forming a right angle, and feet flat on the floor.
