Kronos
A tablet-first platform for coaches to create and deliver smarter training routines.
Strongline is a digital platform for fitness coaches to create and manage personalized workout routines for their athletes. It streamlines the trainer’s workflow and introduces a structured way to deliver and visualize exercises, especially in contexts where routines were previously shared via Excel or text messages.
Role & Scope
Led the design from concept to delivery over a five-month period. I worked alongside another designer and a dev team of four, collaborating closely with the client and presenting weekly progress in joint sessions with the team lead.
The product was built as a tablet-first web app to reflect the real world use case of trainers working on the gym floor.
My work included user interviews and testing with real coaches, wireframes, high-fidelity design for tablet, and hands-on implementation support.
I adapted an existing design system and extended it with custom components like exercise cards and filtering systems tailored to the product’s needs.
Outcome
The final experience supports a smoother, more intuitive workflow for trainers and positions the product to scale beyond on-site facilities. Strongline now offers a clearer, more engaging interface aligned with the pace and needs of modern fitness professionals.
