What is the best exercise to improve flexibility?

Stretching is the best exercise to improve flexibility because it specifically targets the muscles and tendons, helping to increase their length and elasticity. Regular stretching routines can enhance the range of motion in joints and prevent injuries by allowing muscles to work more efficiently. Incorporating various types of stretches, such as static, dynamic, and ballistic stretches, can help in developing overall flexibility, making it easier to perform a variety of physical activities with improved movement efficiency.

In contrast, lifting weights primarily focuses on building muscle strength rather than enhancing flexibility. Eating well is essential for overall health and can support physical performance, but it does not directly affect flexibility. Running can improve cardiovascular endurance and strengthen leg muscles, yet it does little for overall flexibility unless accompanied by a dedicated stretching routine. Thus, stretching stands out as the most effective exercise for specifically improving flexibility.
