After reading the answer, I feel that there are still a few useful words. Others agree that it depends on how to press it. It is comfortable to do moderate exercise every day, without tingling, at most a little more than stretching. Long-term practice will make you soft and flexible, and your range of activities will also increase. Personally, I suggest stretching for 2-5 minutes at a time (that is, stretching from the fascia to getting up and stopping stretching), not exceeding 20 minutes (at most).
Softness is basically an innate quality. Another factor is whether you practiced when you were a child. These two are the most important conditions. Then, have you continued to practice? You can take leg press as the degree of rest, even if it hurts a little. Of course, this degree is up to you. If you have friends around you, you can ask them to help you practice. After a long time, your body will not only adapt to stretching, but also like stretching. After a long time, you will find that the stretching range is large and it will not hurt too much. Nowadays, many people in leg press are testing their physical limits, and the bottom line is just not to be hurt. Although the requirement of Wushu soft opening is lower than that of dance, because of its nature, some teaching about soft opening exercises will be very simple and rude, except for some who are particularly tolerant of self-abuse (I was like this at that time, because when I was a child, the teacher didn't press hard, not only did it not form a shadow, but even if I didn't take interest classes, I still pressed hard every day. It was self-abuse. Although I can't stick to it for the time being, I can at least stick to it and have a chance to keep practicing. It is difficult for people with good congenital conditions to persist, and such training is not good.
