As far as I know, in the 22 sets of teaching videos of China Dream Team, there is back teaching, which makes it easier for learners to master the details and essentials of each movement. After watching the previous teaching, learners can consolidate and improve their skills through the later teaching.
At the same time, aerobics teaching video also provides a variety of training programs with different difficulty levels to meet the training requirements of learners with different levels and needs.
