Transformations Studio boosts member accountability and engagement
Fitness studio rolls out the Lumen program to their clients and doubles their Lumen device order

Background
Transformations, a high-end, “by-appointment-only” studio fitness club located in Hilo, Hawaii, has been long dedicated to helping clients achieve lasting body composition changes through personalized training and nutrition. Their key challenge was keeping clients accountable and engaged in a fitness journey where progress can sometimes be gradual or difficult to measure and recognize.
To bridge this gap and nurture engagement, Transformations integrated Lumen, a handheld metabolic tracker, into their coaching programs and set itself apart by offering something unique: real-time metabolic tracking, paired with hyper-personalized plans.
Challenges: Making the invisible, visible
Traditional programs often emphasize aesthetics like weight loss and muscle gain, yet clients often lose motivation and accountability when results aren’t immediately visible, even if their metabolism is improving.
Owners, Heather and Garrett, both accomplished athletes and coaches, had full confidence in their fitness teachings and methodology. Their programs delivered results; but without immediate aesthetic proof, many members struggled to stay motivated.
Creating hyper-personalized nutrition and training plans was also time-consuming and relied on subjective assessments, making it difficult to track real progress.
Solution: Integrating Lumen into gym programs
Heather and Garrett first discovered Lumen as users, experiencing the benefits of optimizing their own metabolic health. After seeing the positive impact on their personal goals, they decided to introduce Lumen to their members and make it a part of their program.
“Lumen was the missing link to keep clients engaged and on track to their goals.”
- Garrett Hall, Pro Trainer at Transformations
Expanding the program for greater impact
Transformations extended their 12-week program to 22 weeks, introducing Lumen at week 12 to boost both results and member retention.
With real-time metabolic tracking, trainers were able to fine-tune workouts and nutrition based on each client’s fat and carb burn, leading to more effective weight loss and improved fitness performance. As clients’ Lumen Flex Scores improved — indicating greater metabolic flexibility — motivation stayed high, and long-term success became more achievable.
“Lumen has truly been a game-changer. It’s taken our personalized coaching to the next level, delivering results our members never thought possible.”
- Garrett Hall, Pro Trainer at Transformations
Enhancing engagement with daily feedback
Lumen delivered daily metabolic insights, keeping clients engaged and accountable. Members could see how their bodies responded to food, fasting, and exercise — unlocking a level of personalization traditional metrics lacked. Regular check-ins sustained motivation and long-term commitment.
Adding a unique competitive edge
Beyond improving client results, Lumen differentiated Transformations from other gyms, increasing retention and client satisfaction by delivering real-time, personalized guidance.
“In fitness, retention is everything – the longer we keep members connected to Transformations, the more successful we are. Lumen increased engagement, which directly improved client retention and business growth. When clients see progress, my job gets easier.”
- Garrett Hall, Pro Trainer at Transformations
