CHALLENGE

Underutilized
Body Composition Analyzers


InBody USA installed body composition analyzers in 30+ Southern California gyms, but adoption remained low. This pattern was unique to U.S. markets, where the same devices succeeded in South Korea.

Based on operational insights, we found that group fitness challenges increased device usage when trainers actively helped members with the scanning process. However, manual challenge management was a burden for trainers, creating the need for an automated solution.



Group fitness challenge?
A type of group training where members set shared goals, such as losing weight, compete with each other, and work toward achievement together.


RESERARCH

Understanding Operational Challenges
How many people use the device? How can we make trainers use our fitness challenges?


To uncover why devices went unused, we conducted comprehensive research across 6 gyms in SoCal during peak hours (6–8 p.m.), including a 3-month embedded study at Gold's Gym where we observed daily operations and interviewed 15 trainers.


Across all gyms, I was in the same space as more than 300 people in total, yet none of them used the devices, except for a few members who were training with personal trainers.


Through observations and interviews, I discovered that members wanted to use the devices but felt uncomfortable scanning themselves in front of others and couldn't interpret the numbers without guidance.

  • Felt uncomfortable scanning themselves in front of others

  • Couldn't interpret body composition numbers without guidance

Member Accessibility Barrier 

Members struggled to interpret the data without trainer guidance, creating dependency on already-busy trainers.

Low Motivation




The operational challenges caused trainer engagement to drop, diminishing use of body composition data.

Despite these challenges, fitness challenges remained valuable because they naturally aligned body composition tracking with long-term behavior change if we could reduce operational friction while maintaining human guidance.


KEY INSIGHT

Adoption failed not from lack of user motivation, but because trainers bore all the operational burden without proportional rewards.

DEFINE

Key insight: Three-way disconnect

Research Question

"How might we integrate body composition insights into trainers’ natural workflow in a sustainable way, so that it feels like a benefit rather than a burden?"

IDEATION

From Trainer Burden to Trainer Tool

Initially, we thought that a data-syncing dashboard for managing fitness challenges would motivate trainers to adopt the device by eliminating manual record-keeping.

While it reduced operational friction, it didn't directly address trainers’ need for recognition, ownership, and visible impact.



Not Just Automation, but Motivation

While automation saved time, it didn't give trainers a compelling reason to initiate device usage with members in the first place.


How can we make this more rewarding?

To motivate trainers, we designed a challenge management dashboard that reframes them as “expedition partners.”




Through the dashboard, trainers build fitness challenges using body composition data, track member progress, and guide members through shared fitness journeys, making their impact visible and socially recognized.

DESIGN

Driving Engagement Through Gamification


To boost trainer engagement, I designed a dashboard that visualizes trainers' direct impact on member success through a ranking system and real-time challenge progress, creating a powerful feedback loop that fosters sustained use.

Enabling Proactive Coaching

Trainers can launch fitness challenges in seconds using an AI feature that recommends optimal parameters (duration, metrics, frequency), eliminating the high-friction manual setup process. (5 minutes ➜ 20 seconds)

By automating administrative tasks, the system freed trainers to engage members in meaningful conversations about what their body composition changes meant for their fitness goals, transforming intimidating numbers into actionable insights.

User Testing

Test and Iterate


We iteratively conducted A/B design testing with trainers to validate which feedback mechanisms most effectively increased trainer engagement.

Lesson Learned

Designing for All Stakeholders


This project taught me that equitable access requires restructuring systems to support everyone involved, not just one user group. By automating trainer workflows and visualizing their impact, we freed them to provide the guidance members needed, creating a system where both parties benefited.



Designer as Bridge Builder


Regular co-design sessions with developers and PMs helped me translate insights at gyms into solutions the whole team could align on, proving that designers mediate not just interfaces, but team understanding.
