today during the flexibility training class, teachers are helping my classmates and me to do the passive stretching training for flexibility, this is important if you want to dance more elegantly. the teacher asked me to lay on the mats, take a deep breath and relax, then they grab my legs and slowly push my legs to 180 degrees, this is a very effective way to get the middle split despite it is a little painful. so we have been told to shout it out when we feel the pain. because shouting can help we inhale and exhale, which can relax our tighten muscle, can reduce the pain, can let us stick to the end, and gain flexibility.
this is ordinary flexibility stretching training for the professional dancer.

Declaiming：
Please don't imitate the training in this video by yourself. The students in the video are the professional that have been studying for more than years and teaching under professional supervisor, 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 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 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 are all adults, they pay tuition to learn, so they knew what they need to go through, and they recognize the teaching method.
