Meet the Client

Belle Hutt is a world-class personal trainer and fitness influencer who has transformed her own wellness journey into a global community. After publicly sharing her experience living with narcolepsy, an often misunderstood sleep disorder, she made it her mission to show that physical fitness, mental well-being and everyday movement are accessible to everyone, regardless of time constraints or physical limitations.

Starting her fitness community during the early stages of the COVID-19 lockdown, Belle quickly built a loyal audience through live sessions, laser-focused accountability, and an authentic tone. With thousands of members engaging daily, she recognised the opportunity to scale beyond social media and create a mobile‑first experience that would serve all time zones, all levels and all circumstances.

The challenge? To translate her in‑person energy, motivational style and inclusive ethos into a beautifully designed app that supports her global audience. From live-stream classes to on-demand workouts, progress tracking, community leaderboards, and health-data integration, Belle wanted a platform that was as dynamic as her community. Partnering with Sonin, her vision was to build a scalable, premium mobile product aligned with her brand while delivering meaningful outcomes for her members.

Engaging a fanatic fitness audience, in a personal way, across 90+ countries

For a fitness brand built on personal connection and energy, scaling to mobile while preserving that sense of trainer‑to‑trainee intimacy is critical.

By partnering with Sonin, Belle Hutt translated her one‑to‑one coaching ethos into a mobile product that broadens her reach without diluting the experience. The result: a truly global fitness community, not just another fitness app.
