Fitness for Fitbit
2022-2024
Overview
I led the end-to-end fitness experience for Pixel Watch 3 and co-defined the future of fitness at Fitbit alongside PM partners. Building on the foundation of the first-gen Pixel Watch, we launched key features including heart rate training, advanced running metrics, and Readiness & Load training. I also initiated a generative AI effort that catalyzed a broader strategic shift toward personalized, intelligent fitness coaching across Fitbit.

UX Design lead
/ 2 direct reports
- Led the end-to-end fitness experience by guiding design execution and feature development
- Co-defined fitness strategy with PMs to shape the product direction of Pixel Watch products
- Pioneered genAI integration into the fitness experience, influencing the Fitbit’s larger vision
Impact
Defined and launched Pixel Watch 3’s fitness experience and influence Fitbit’s strategic direction
Challenge
Pixel Watch 3 was Google’s third-generation wearable. With growing competition in the health & fitness space, we needed to transition from a data tracking and dashboard product that Fitbit once was, to a coaching product in order to differentiate through intelligence and coaching.
How might we redefine the fitness experience to feel proactive, personalized, and motivating?
Defined product strategy
I worked with the PMs on the team to define a product strategy for Pixel Watch 3. We are aiming to build a world-class wearable for fitness enthusiasts. Start from cardio exercises, which is built on the advantage of heart rate tracking on Pixel Watch. And we can expand to other fitness verticals in the long-term.
Create and communicate the vision
I led 2 designers to work closely with our PM team to create an end-to-end experience to demonstrate the fitness coaching experience across watch and mobile. This artifact shows the team’s ambition with a one-year outlook, so it is grounded in reality but communicates the direction we want to go.
Guide design execution
I managed 2 designers and coached them on the design process and collaboration with their peers. I advocated for updating our UXR testing methods to test the wearable in realistic settings to get better user feedback.
Build your custom run
Create warmups, cool downs, intervals and pace and HR targets. Then access saved workouts and track your PRs.
In-workout coaching to keep you on track
Start one of your custom runs and get audio and haptic cues for when to sprint, cool down or maintain pace.
Know what your body is ready for each day.
We worked with a clinical expert and introduced a new metric that can inform how hard you work your heart.
Analyze your run
Advanced motion sensing measures your cadence, stride length, vertical oscillation and more to help improve run performance.
Impact
- Launched Pixel Watch 3’s fitness experience and influence Fitbit’s strategic direction.
