Why am I so stiff in dancing?

The stiffness in dancing is mostly a result of not being familiar with the dance or not having enough confidence in yourself. The stiffness of the movement is due to the lack of coherence and stretch, not coherent is not skilled enough, more practice, the formation of non-conditioned reflexes, the degree of fluency will help. As for the degree of stretch is often said to be unable to release, mainly may not be a long time to dance, or lack of experience in performance, making the dance more like a drill, the lack of details and personal characteristics, which requires the teacher and the audience's feedback.
