taekwondo is not a sport for weakers

Please don't imitate the flexibility training in the video.
This video is for documentary only.
today in my son's taekwondo class, teachers are helping him and his classmates to do the passive stretching training for flexibility, this is important if you want to kick higher. the teacher asked him to lay down on the floor, open his legs and relax, then he slowly press down his legs to 180 degrees, this is a very effective way to get the middle split despite it is a little painful. so he have been told to shout it out when he feel the pain. because shouting can help him inhale and exhale, which can relax his tighten muscle, can reduce the pain, can let him stick to the end, and gain flexibility. and I was there, show my son all my support. I have to admit that taekwondo is a training can man cry. really hard.
this is ordinary flexibility stretching training for the professional athletes.

Please don't imitate the training in this video by yourself. The students in the video are the professional athletes and have been studying for more than years. The teachers have more than years of teaching experience, so they dare to train students like this.
The students in the video are challenging to a higher level of flexibility, so the training of the teachers is more strict. But this kind of training is harmless because the students have already warmed up before the training, the bones and muscles have been totally relaxed, after the training, the students will get the corresponding auxiliary massage to eliminate the muscle pain.
Everyone has limited ability to withstand the pain, so you can see some of the students shouting or crying in the video, and some students are not. but This is good in flexibility training, If it is not painful, that means students have not broken his or her own limit, then he or she will not make progress, and such pain is controllable. also shouting or crying helping them inhale and exhale, relax the tighten muscle, relieve the pain, then they can hold in that position for enough time, that is the goal when doing the flexibility stretching.
the students in this video, they pay tuition to learn, so they knew what they need to go through, and they recognize the teaching method.
