Focus
Gym management system
I led the UX direction across both apps alongside one designer — owning client communication, the full trainer and trainee journeys, and reviewing all output before delivery.
01
UX direction
Defined the experience for both apps: trainer scheduling and client management, trainee workout flow and session tracking
02
Live workout experience
Designed the step-by-step workout session — exercise by exercise, timer, sets, and seamless progression
03
Trainer-trainee connection
Designed the request, accept, and program assignment flow between both sides of the product
04
Review & quality
Reviewed all design output and ensured consistency and quality across both apps
The workout is a live experience, not a list. Most fitness apps show you a workout as a static list. We designed it as a guided session — one exercise at a time, with a timer, set counter, and a clear path to the next movement. The trainee is never wondering what comes next or how long they have.
Trainer and trainee connected, not merged. The two apps share data — schedules, programs, progress — but the experience of each is built around what that user actually needs in the moment. The trainer sees their day. The trainee sees their workout. The connection happens in the background.
Premium feel built for resale. The apps would be sold to gyms and carry their branding. Every design decision — spacing, hierarchy, interaction quality — was made with the end user in mind, not just the gym buying the product. Premium experience first, white-label second.
One ecosystem. Two experiences.
01
Trainer app Daily schedule, client profiles with health records, session details, and program assignment — all in one place. Trainers can review who's coming in, what they're working on, and manage new client requests without leaving the app.
02
Trainee app Class schedules, trainer profiles, subscription status, and today's workout — surfaced clearly and without friction. The trainee always knows what's happening and what's next.
03
Live workout session Exercise by exercise. Timer running. Sets counted. One tap to move forward. The live session mode turns a training plan into a real-time guided experience — the trainee follows along, the plan does the thinking.
04
Request & connect flow Trainees request trainers. Trainers review profiles and accept. Programs get assigned based on level — beginner, intermediate, advanced. The connection between trainer and trainee is structured, clear, and tracked from day one.
Premium, smooth, and connected.
The client's feedback: the harmony between the two apps felt smooth, and the experience came across as premium and polished. Two separate user journeys — trainer and trainee — that work independently and together, without either feeling like an afterthought.
