I structured the experience around three product pillars:

Client motivation
Client motivation
I designed the experience to keep clients motivated through consistent, human connection. They could regularly check in with their coach, share how they felt, report & track their progress, and get feedback on their form — helping them stay committed, even when training alone.

I designed the trainer experience to mirror how they work in the gym — fast, flexible, and intuitive, without needing to learn a new system. Whether the session called for circuits, sequences, home or gym setups, the tool supported their ability to adapt to each client’s context.

Trainers could quickly build sessions, assign side activities like walks or yoga, and see each client’s progress at a glance. A unified dashboard gave them the context they needed to coach effectively in real time.

Product scalability
Product scalability
Although the pilot included just 5 trainers and 100 clients, I designed the system to scale far beyond that. From the beginning, I considered how a coach could support 50 or more clients without losing quality.

I prototyped AI tools — like plan builders, prompts, and smart insights — to reduce repetitive work and let trainers focus on people, not admin. The foundation was built to scale without needing to be rebuilt later.

One key challenge was balancing trainer flexibility with a clean, intuitive experience. Coaches vary widely in how they build and adapt workouts. I designed a modular system that supported diverse coaching styles while keeping the interface simple and clear.

This project pushed me to think across product, service, and systems design, to deliver an experience that worked at launch, and could grow with demand.
