Which type of exercise is best for improving flexibility?

Stretching exercises are specifically designed to improve flexibility by elongating muscles and tendons, allowing for a greater range of motion around a joint. When performed regularly, stretching can enhance flexibility, reduce muscle stiffness, and improve overall physical performance. Stretching targets the muscles and connective tissues directly, making it the most effective approach to achieving increased flexibility compared to other forms of exercise.

Aerobic exercises primarily focus on improving cardiovascular endurance and metabolism, while resistive training targets muscle strength and power. High-intensity interval training, on the other hand, is designed to improve both aerobic and anaerobic fitness through short bursts of intense activity followed by rest or low-intensity periods. While these exercises may improve overall fitness and may have some indirect benefits for flexibility, none are as directly effective in enhancing flexibility as stretching exercises are.
