Posture is intricately related to overall fitness as it impacts balance, stability, and the efficiency of movement. Good posture minimizes strain on muscles and ligaments, reducing the risk of injuries and chronic pain, particularly in the back and neck. It allows for optimal lung capacity, enhancing breathing during physical activities. By promoting muscle engagement in the core and stabilizing structures, proper posture supports effective functioning during exercises and daily tasks, contributing to enhanced athletic performance and overall well-being.
