This article focuses on optimizing business processes in the fitness services sector, using the modeling of the children’s fitness service delivery process as a case study. The objective of the study is to formalize and analyze the sequence of actions to improve the operational efficiency of a fitness club in an increasingly competitive environment. The research methodology is grounded in process management principles and employs IDEF0/IDEF4 notations to detail the key stages of service delivery. The findings include a contextual diagram of the business process, with a detailed breakdown of the core service delivery block. The study demonstrates how customer input requests are transformed into the final product–children’s fitness services–while accounting for regulatory and infrastructural factors. To further enhance efficiency, the application of GAP and ServQual models is proposed. The results can be utilized to standardize, unify, and increase the transparency of business processes in fitness clubs.
