Yoga precautions
As a practitioner, you should always follow the natural laws of yoga practice in a gradual manner, not compared to others. Many people in the early stages of practice always think that the practice of yoga requires good flexibility, see around other practitioners or coaches can do more than their own stretching or more difficult movements, they will be eager to do that, which is often because of the rush and hurt their joints and muscles, the effect of the practice will also be counterproductive.
There's another part of the practice that can't be ignored: the warm-up, which is the preparation for the exercise, or some of the simpler yoga poses. If this is missing, you are likely to get injured or have difficulty completing the movement. For example, in power yoga practice, it is easy to get tense when doing the upward dog pose without proper preparatory exercises. Once you can't support it, the joints will make the effort and the body will be vulnerable to injury.
