Runner: Founded in early 2008, the biggest selling point is installment payment. Wu Yanhua, the head coach, was originally a Pilates coach at Jade Bird Fitness Club, and he was not very interested in courses other than Pilates.
Allen: The full name is Allen International Fitness Instructor Training Center. I don't know why there is only one word difference between Allen International and British International. Founded in early 2009, it is said that a runner, a mentor who was not hired, led several students out to engage in it. It is known that all the students are seven years old. As for trainees, we haven't learned it yet, and I don't think so.
Aojian International: Founded in early 2008, the founder is the personal education director of Huaao Zhongxingni Club. Coaching teaching is mainly based on fixed routines, but students' independent arrangement ability is not flattering.
