The length of yoga practice will have different effects on the improvement of flexibility. Generally speaking, to achieve good flexibility, it is necessary to keep practicing for several weeks to several months, which depends on the individual's physical flexibility and the frequency and duration of practice.

Beginners may only need a few weeks to see obvious progress, while some people with stiff bodies may need longer or even years to achieve the same effect. Therefore, to improve the flexibility of the body, we need to keep practicing and gradually increase the difficulty and depth.

In addition, it should be noted that yoga is not a quick and effective tool, and it needs long-term persistence and patience to see obvious results. Therefore, it is suggested that beginners should be patient and persistent, and keep practicing to get the best results.
