The fundamental principle of good posture revolves around aligning the body's segments in a way that minimizes strain on muscles and ligaments, while allowing for efficient movement. Among the options provided, evenly distributing weight on both feet is crucial because this helps to maintain balance and reduces excessive stress on any single part of the body.

When weight is distributed evenly, it supports the body's natural alignment and promotes a stable foundation. This helps in preventing muscle fatigue and discomfort, contributing to better overall posture. Distributing weight inequitably, such as placing most of the weight on the balls of the feet, can lead to instability and improper alignment, which may result in pain and postural issues over time.

In contrast, while maintaining a straight back and keeping shoulder blades retracted are important aspects of good posture, they are not the primary factors. They are more about adjusting the positioning of the spine and shoulders rather than foundational balance, which weight distribution significantly influences. Therefore, the emphasis on even weight distribution effectively encapsulates an essential element of achieving good posture.
