Wearable data integration with fitness platforms now delivers instant health insights with real-time workout recommendations to life-saving revelations.
In this episode of the Wexer Podcast, CEO Paul Bowman chats with Marco Benitez, CEO & Co-Founder of ROOK, to explore how behind-the-scenes technology is powering a new wave of hyper-personalized health experiences. He reveals why smart data might be the most valuable asset in fitness today.
While ROOK might not be the “sexy front-end” of fitness tech, as Marco puts it, the work happening behind the scenes—structuring wearable data for software developers and operators—is transforming the way we approach wellness, personalization, and engagement in digital fitness.
Marco’s Journey From Martial Arts to Medical Data
Marco’s journey into health tech started long before ROOK. He was a national Taekwondo champion in Mexico, training since he was just five years old.
Taekwondo taught him about discipline and structure, which led to an equal passion for science and data. He became a biomedical engineer, later moving into clinical trials for Big Pharma, working on oncology, vaccines, and respiratory diseases. He was also an early adopter of wearable tech—using devices like Polar’s chest straps as far back as the early 2000s.
“I believe that hyper-personalization is the future.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
Building the Bridge Between Fitness and Healthcare
The healthcare and fitness sectors are notoriously siloed. Fitness focuses on performance and lifestyle, while healthcare zeros in on diagnostics and treatment. But wearables are beginning to blur that line.
Paul shared a personal story about how his doctor used 10 years of his WHOOP data to guide a treatment plan—proof that the worlds are starting to converge.
Marco echoed this, adding that his own father’s life was likely saved by a wearable device detecting an ECG anomaly early. These aren’t just fitness accessories anymore—they’re health tools.
“The health industry is starting to see how fitness is improving in a lot of things. Doctors are now considering information about fitness to help people get better.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
How Rook Works
So, what does ROOK actually do? Simply put, ROOK is an API that connects to hundreds of wearables and medical devices, cleaning and organizing the data so developers, fitness clubs, and health apps don’t have to deal with multiple integrations. Rook supports 300+ wearables and medical devices.
Instead of integrating Apple Watch, Garmin, Fitbit, continuous glucose monitors (CGMs), lab testing, and blood pressure monitors separately, ROOK does it all through one API and webhook. This cuts integration timelines from 24 months to just one.
ROOK’s role is backend. It’s not the interface users see, but it’s the engine that powers hyper-personalized, data-informed user experiences.
“Rook helps operators customize the end user experience.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
Fitness Wearables & Data Stats You Should Know
- 🔁 1 in 5 U.S. adults uses a fitness tracker or smartwatch regularly (Pew Research).
- ⏱️ Wearable users are 44% more active than non-users on average (Johns Hopkins University).
- 🧠 Personalized fitness recommendations based on wearable data increase content engagement by up to 28% (Wexer Podcast, Ep. 64).
- 😴 Sleep tracking is the #1 feature users engage with on wearable devices (Statista, 2024).
- 🩺 82% of wearable users say tracking helps them better understand their health and fitness (Deloitte Global Survey).
- 💡 Operators who integrate wearable data see improved member retention and program adherence—especially when tailoring workouts to recovery scores.
- 🔗 Wearable data integration can reduce app churn by up to 30%, especially when used to trigger personalized push notifications or workout suggestions (ROOK internal data).
- 🏋️ Over 300 wearables and medical devices can now be connected via a single API using platforms like ROOK.
- 📈 Global wearable market expected to reach $63 billion USD by 2027, driven by demand for health monitoring and personalized fitness (Allied Market Research).
- ❤️ Real-time heart rate monitoring is the most commonly used biometric, followed by sleep quality, HRV, and step count.
- 🚶♂️ WHO guidelines recommend 150 minutes of activity per week—wearables help users stay accountable and track progress toward this goal.
- 🔍 Data-driven fitness programs lead to 20–40% higher completion rates compared to generic, one-size-fits-all programs.
How Wearable Data Encourages Engagement, Habit Loops, and Retention
For digital fitness operators, personalization isn’t just a nice-to-have—it’s directly tied to user engagement. This creates a contextual content loop where the workout isn’t just “on-demand,” it’s on point.
With this kind of actionable data, operators can guide users based on their recovery scores, sleep patterns, or even stress levels:
- Didn’t sleep well? Offer a restorative stretch or meditation.
- Low recovery score? Skip HIIT and push a low-impact workout.
- Elevated glucose? Recommend content on nutrition or rest.
“Clients are 28% more likely to do particular content if it’s recommended to them based on their wearable.” ~ Paul Bowman, CEO of Wexer ~
Future Use Case: A Car That Knows You’ve Had a Bad Day
Marco shared an especially futuristic use case—one of ROOK’s clients in the automotive industry is integrating wearables into the driver experience. Your car could adjust the lighting, air conditioning, or even music based on your wearable’s stress data. This isn’t just a gimmick. It’s part of a growing trend to connect wellness touchpoints across all environments—home, gym, car, and even the workplace. Your car becomes part of your wellness journey beacuse it knows you had a rough day and responds to it.
How Privacy, Compliance, and Consent Play Into Wearable Data
Of course, personalization brings up critical concerns about data privacy and trust. ROOK, with its healthcare roots, was built from day one to be HIPAA, GDPR, and SOC 2 compliant. Security isn’t an afterthought—it’s built into the product DNA. This makes it easier for operators to plug into ROOK without worrying about breaching trust or legal boundaries.
“It’s not just about cloud infrastructure—it’s about company behavior, SOPs, governance. We take it very seriously.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
What Wearable Data Metrics Actually Matter?
When asked what data points are becoming more meaningful, Marco pointed to sleep.
Sleep, stress levels, glucose, and heart rate variability are now foundational in creating fitness journeys that are both effective and sustainable. Younger generations, Marco noted, are skipping Saturday night parties to get solid rest before 6 AM workouts. The behavior shift is happening—and the data is driving it.
“It’s a new era of information. Before, no one talked about the importance of sleep.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
How Do You Create Hyper-Personalization Without the Creep Factor
Can too much personalization get… weird?………………..Yes—and that’s why consent and simplicity are key.
Let users choose how deep they go. Some just want basic trends. Others want to analyze 60 variables a day. The platform needs to support both journeys. Read more about how Biometric Data & AI Fuel the Future of Personalized Fitness.
“Don’t overwhelm the user. Focus on a few meaningful insights and keep it simple.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
What’s Next For Wearable Technology
Marco is bullish on wearables becoming ubiquitous—and smarter.
From micro-pills that scan your body to home AI that nudges you to move, the future is about creating a connected ecosystem where every space—from your car to your living room—nudges you toward healthier habits.
“Everything is going to be connected. Your home, your app, your fitness club. That’s huge.” ~ Marco Benitez, CEO & Co-Founder of Rook ~
What Is The First Step For Fitness Operators?
Data is no longer just for analysts or elite athletes. With tools like ROOK, every club, app, and operator can tap into real-time health data to engage, retain, and truly help their users. The winners will be those who act now—those who build smart systems that connect wearables to actionable outcomes. Because at the end of the day, content without context is just a screen.
Take the first step and integrate the API. It’s free to start. You’ll be surprised how much information your users are already generating—and what you can do with the data.
