What does the term "good posture" refer to?

The term "good posture" primarily refers to the vertical alignment of the body. This alignment ensures that the body's segments are properly positioned to support efficient movement and function. When a person maintains good posture, their head, shoulders, spine, hips, knees, and ankles are aligned in a manner that allows for optimal balance and minimizes strain on muscles and ligaments.

Good posture contributes to overall health, reducing the risk of injury and fatigue during daily activities. Additionally, it enables better breathing and circulation, creating a foundation for physical performance and overall well-being. While balanced muscular strength, flexibility in the spine, and correct breathing technique can all influence how posture is maintained, they are more supportive elements rather than the definition of good posture itself. Vertical alignment is the most direct representation of what is meant by "good posture."
