Which two types of stretching can improve flexibility?

Static stretching and dynamic stretching are both effective methods for improving flexibility, which is essential for overall physical fitness and performance.

Static stretching involves holding a stretch for a period of time, typically between 15 to 60 seconds. This method allows the muscle fibers to lengthen gradually, which can enhance flexibility over time. It is often performed at the end of a workout to help with recovery and muscle relaxation.

Dynamic stretching, on the other hand, involves controlled movements that go through a range of motion. It is typically done prior to physical activity to increase blood flow to the muscles, improve range of motion, and prepare the body for more intense exercise. This type of stretching mimics the movements of the activity that follows, which helps to enhance athletic performance.

Together, these two forms of stretching can effectively prepare the body for movement and increase the overall flexibility of muscles and joints, making option B the most appropriate choice for improving flexibility.
