Which of the following is a benefit of improving flexibility?

Improving flexibility offers a significant benefit in enhancing performance in everyday activities. When a person possesses greater flexibility, their muscles and joints can move through their full range of motion more effectively. This increased range allows for smoother movements and improved coordination, making daily tasks—such as bending, reaching, twisting, or lifting—easier and more efficient. Enhanced flexibility can lead to better posture, decreased risk of injury, and an overall improved ability to engage in physical activities.

While other choices mention benefits like enhancing circulation and reducing muscle soreness, they aren't as directly related to flexibility as the impact on everyday activities. Muscle mass increase is not influenced primarily by flexibility; rather, it is more related to strength training and resistance exercises.
