Do you need to change your movements frequently when practicing yoga?

The purpose of yoga is to cultivate self-cultivation and lose weight. If you want to cultivate your self-cultivation, you can change at any time and follow your feelings. If you want to lose weight, it is more targeted. If you want to lose weight, you should mainly practice related movements where you want to exercise. I used to practice every day. After a long time, my muscles got used to that kind of action. At this time, it means that practice has improved that muscle, so I can choose to continue practicing this action, lengthen the time of this action, or change the action. So it's up to you. My suggestion is that some can change frequently, others can't, and have targeted and focused exercises.
