Take a good look at the fitness courses inside, which are very systematic, including introductory, intermediate, fat reduction, shaping, stretching and so on, and very comprehensive. I just changed from a novice to a fitness expert. The course will teach you how to exercise step by step and the essentials of each movement. The standard of each movement can also be displayed on the big screen, which can be corrected in time, and the more you practice, the more accurate you are.
