The type of exercise that improves flexibility is typically referred to as stretching exercises. Stretching can enhance the range of motion in joints and muscles, reducing stiffness and improving overall mobility. Different forms of stretching, such as static, dynamic, and ballistic stretches, can be incorporated into warm-up or cool-down routines. Regular flexibility work is essential for injury prevention and can improve performance in various physical activities. It is important to approach stretching with proper techniques to avoid overstretching, ensuring safe and effective improvements in flexibility.
