2. Sweating is detoxification, which excretes moisture and cold blocked in the meridians and joints in the body through sweat glands, thus dredging the meridians and joints of the whole body and improving blood circulation. Therefore, once you exercise, you will sweat as if you were caught in the rain. That is sweating too much. The moisture and cold in your body are heavy, which is abnormal and needs regular practice. If you don't practice hard, take a deep breath and get tired because you are distracted, you will definitely not sweat; If you practice hard and still don't sweat at all, it means that the part you practiced at that time has been heavily silted up and you can't sweat anymore. You need to practice more to clear it. It is normal to sweat a little when doing every exercise, but don't sweat a lot.
3. Whether it is leaning back or any other posture, it varies from person to person, because everyone's physique is different. Your breathing is deep and long, and the part of this asana exercise is healthy, so you can keep several groups of breathing; If this pose is difficult for you, you just need to do your own limit. Don't go beyond the limit, don't force yourself, don't compare with others. Everyone's physique is different, and the limit is different. Yoga is not a competition, you just need to reach your limit every time, and slowly you will find yourself making progress day by day. Beginners learn to keep fit, then learn to keep in good health, and learn the deep cultivation of the mind.
