Which method should be used to improve shoulder flexibility differences?

To improve shoulder flexibility differences, focusing on increasing specific range of motion is the most effective method. This approach involves targeted stretching and mobility exercises that are designed to enhance flexibility in the shoulder joint and surrounding muscles. By isolating the shoulder and working on its specific movements, individuals can address any limitations or imbalances, fostering greater overall flexibility. This method not only helps in improving the range of motion but also plays a crucial role in preventing injuries and enhancing performance in various physical activities.

Other options, while they may contribute to overall fitness or strength, do not specifically address the need for improving flexibility in the shoulder. General fitness can be beneficial, but it lacks the specific focus necessary for targeting shoulder flexibility. Reducing weight lifting might inadvertently harm muscle strength and does not provide the necessary engagement of the muscles required for flexibility gains. Concentrating solely on upper body strength may lead to tightness in the muscles without enhancing flexibility, thus not adequately addressing the flexibility differences in the shoulders.
