Technical Field

[0001] The invention relates to the technical field of ligament stretching, and in particular to a leg ligament stretching training device for dance teaching and training. Background Art

[0002] Dance teaching is the act and process of enabling the learners to master dance knowledge, learn dance skills, and improve dance ability through various methods. There are three mainstream forms of dance teaching, namely traditional on-site teaching, distance learning, and dance teaching video teaching. The teaching method is oral and hands-on teaching.

[0003] During dance training, in order to ensure the safety of the muscles and ligaments of dancers, stretching movements are usually required. Existing dance leg ligament stretching usually requires the cooperation of teachers or dancers to achieve stretching movements, and when performing stretching movements, it is necessary to assist the dancers or teachers to press and stretch the dancers. However, if the assistant dancers or teachers cannot control the intensity of stretching well, it is easy to cause excessive stretching intensity to the ligaments and muscles of the dancers, thereby causing the ligaments and muscles of the dancers to be overly strained, affecting the subsequent training of the dancers, and even affecting the later dance career of the dancers, and the safety performance is insufficient.

[0004] Therefore, the present application provides a leg ligament stretching training device for dance teaching and training to meet the needs. Summary of the invention
