It's normal to practice for the first time without exercise for a long time. It shows that the muscle load is relatively large, and it is necessary to distinguish between soreness and pain. If it is pain, you need to pay attention to the weight of suitable fitness equipment. If it is sore, it is normal. Practice a few more times and you will get used to it. In addition, fitness should not be too frequent, and attention should be paid to proper rest, within four times a week.
