Fitness level has a direct impact on postural alignment. Individuals who engage in regular physical activity are more likely to develop strong postural muscles that support the spine and body. A higher fitness level often equates to better core strength, flexibility, and muscular balance, resulting in proper alignment. Conversely, lower fitness levels may lead to muscular imbalances, contributing to poor posture and discomfort. Regular strength training, stretching, and core workouts can help improve posture over time. Therefore, maintaining a good fitness routine is pivotal for optimal postural alignment.
