Of course it's worth going. Their fitness studio is the best I have ever seen in Nanning. Coaches are much better than gyms and other studios. All are New Zealand certifications, all kinds of advanced certifications. The environment is very comfortable and it is a good place to exercise. I bought private lessons in Chaoyue and Shark Fitness before, and they were not responsible at all. They play mobile phones in class, not as much as I know after three years of fitness. So I strongly recommend Rex fitness studio, which is professional, high in price, low in cost performance and super high in cost performance. Even if you exercise without class, the coach will be responsible for free maintenance, which is incomparable to other gyms and fitness studios.
