At present, most low-cost gyms are made in advance. Before the gym opens, collect money first, and then use the money for operation. This can achieve low cost, but once the sales are weak in the later period, it will be unable to return to heaven, which is why we have seen many gyms close down.
A studio may be more suitable for you than a gym. The cost of studio is low. As long as the operation is done properly, the cycle will be very fast. Moreover, the latter two boutique studios are very popular, and the characteristics you mentioned are more vividly reflected in the boutique studios. There are specialized bicycle theme studios, female theme fitness studios and rowing machine theme studios with distinctive features.
These studios generally adopt a monthly/pay-per-view mode, especially repeat customers, so the requirements for operation/service are particularly high and the advantages are obvious. They have strong social attributes, a sense of fashion, and are fresh and easy to generate word of mouth.
I hope the above answers can help you.
