Which of the following is NOT a benefit commonly associated with flexibility in yoga?

Flexibility in yoga primarily contributes to benefits such as improved range of motion, enhanced balance and stability, and better posture. These aspects are integral to yoga practice and promote overall physical wellness. Improved range of motion allows joints to move through their full potential, enhancing physical activity and preventing injuries. Enhanced balance and stability can be attributed to the ability to move in a controlled manner, which is critical in various poses. Additionally, better posture is often a direct outcome of increased flexibility, as properly aligned muscles and joints support a healthy posture.

In contrast, while increased muscle strength can be a secondary outcome of certain yoga poses that require engaging muscles to hold postures, it is not a direct benefit associated with flexibility itself. Strength is more linked to the resistance and effort exerted during practice rather than flexibility, which predominantly affects the lengthening and elasticity of muscles and connective tissues. Thus, it stands apart from the benefits directly related to flexibility in yoga.
