Design of a digital product for organizing the work of fitness trainers

This thesis focuses on designing a digital product that supports the work organization of personal fitness trainers. It assumes that a significant proportion of trainers rely on fragmented tools and repeatedly deal with administrative tasks related to scheduling training sessions, communicating with clients, tracking attendance, or managing payments. The aim of this thesis is to identify the key problems, needs, and obstacles trainers encounter in these activities and, based on these findings, propose a digital solution that reflects their working processes. The methodological framework of the thesis is grounded in the principles of design thinking. The process involves a literature review and a market analysis of existing tools for scheduling, client management, and fitness services. The main part of the research consists of eight in-depth interviews with personal trainers, whose outputs were analysed using open and axial coding. Based on thematic clusters, problem areas were defined, HMW questions were formulated, and design directions were identified and subsequently prioritised using the Impact–Effort method. From these outputs, the functionalities of the MVP product were determined. This phase was followed by the creation of an information architecture, user flows, and several prototype iterations, which were continuously evaluated through internal review and later verified through moderated user testing. The research revealed several recurring problem areas, particularly in schedule planning and changes, client information management, attendance tracking, payment administration, and client communication. Key trainer needs were also identified, especially those related to clarity, data centralisation, and reducing manual tasks. These findings informed the definition of the main design directions and the prioritisation of functionalities for the future solution. The outcome of the thesis is a comprehensive design of a digital tool that addresses the identified problems and reflects the needs uncovered in the research. The resulting concept was developed through multiple design iterations and provides a foundation for further development and implementation into a fully functional application.
