DexaFit Naples Expands Client Results and Reach with VO2 Master Testing
How a cardiology-led clinic turned safe, on-site metabolic testing into a fast-growing service—without spending a dime on ads.
DexaFit Naples, headed by cardiologist Dr. Leandro Perez, MD, FACC, FSCAI, adopted the VO2 Master Analyzer to deliver precise cardio-respiratory insights for both heart-health patients and fitness clients. The service now draws competitive 60-plus “masters” athletes and strengthens community ties through team-trainer partnerships and local CrossFit events.

"They need to know the testing is available, what it can do and know that the metrics can be improved upon, this is what really motivates them."
-Dr. Leandro Perez, DexaFit Naples
Dr. Perez also serves a unique and growing demographic:
Active individuals over 60 who compete in sport, known as masters athletes. In addition, by partnering with team trainers for a variety of sports and participating in local events like Crossfit, the clinic is fostering deeper community connections, health awareness and human performance aspirations.

The Challenge: Access to Simple, Profitable Testing
Prior to adopting VO2 Master, the biggest issue was access to easy to use cardiopulmonary testing for healthy athletes and longevity clients in the Naples area. Many individuals, including competitive athletes and older adults trying to remain active, lacked local opportunities to get reliable data on their cardiovascular fitness. Additionally, the clinic wanted a solution that could provide testing without requiring symptomatic referral, making it accessible for proactive health monitoring. Their goal was to address this need proactively:
Bridge the gap between cardiac patients and healthy masters athletes who crave precise cardio-respiratory data.
Deliver safe, clinic-based VO2 testing for endurance athletes who want proof their training is effective and heart-safe.
Minimise workflow friction for busy medical staff and ensure repeatability to keep clients coming back.
My clients can see themselves and their live data as they do their VO2 max test and they are really motivated to do their best effort.”
– Dr. Leandro Perez, DexaFit Naples
The Solution: VO2 Master
Dr. Perez reviewed all the products on the market and chose the VO2 Master analyzer for its ease of use, portability and validated accuracy—making it more practical and financially viable than other available devices. He and his staff can now perform VO2 max and RMR tests directly in the clinic and during athletic events, like local CrossFit competitions. One of his staff members came in second place and many competitors wanted to know more about metabolic testing. Unlike larger systems, VO2 Master enables testing in real-world training environments indoors at gyms or outdoors with cycling or running clubs. He is pleased at how the device has been fully integrated into the practice’s workflow, with trainers and patients using the data to set baselines, track progress, and optimize training zones.
Dr. Perez has tested cyclists, runners, hockey players and more. They love the data, they share it with their teammates and coaches.
Baseline Testing & Data-Driven Training Plans
VO2 Master allows DexaFit clients to adopt a data-driven approach to improve their metabolic fitness, health, and body composition by following structured testing and programming interventions:
- Initial Metabolic Assessment: Clients undergo a VO2 Max and RMR test to establish their baseline fitness level and metabolic rate.
- Create a Training Plan: Individualized training plans can be designed, using the data, to target improvements in endurance and recovery.
- Create a Plan to Increase Metabolic Rate: Devise a tailored strategy considering both exercise and non-exercise factors to maximize metabolic efficiency.
- Reassessment & Track Progress: Clients return after 3–6 weeks for a follow-up test to see how their results have changed and adjust the plan accordingly.
The trainers and coaches say; “I will send you more of my athletes“ or “I’m going to bring my team in.” They appreciate it.”
– Dr. Leandro Perez, DexaFit Naples
The Results: 150+ Tests in 3 Months
Since implementing the VO2 Master Analyzer, the clinic has conducted over 150 tests either treadmill based or cycle ergometer for VO2 and also Resting Metabolic Rate (RMR). This has been almost entirely word of mouth, with very little marketing other than some Instagram posts. The visual nature of the testing, combined with personalized data feedback, keeps clients engaged and motivated to improve and return for retesting.
Coaches and athletes have responded enthusiastically, expressing interest in bringing entire teams for assessment. Importantly, the clinic has expanded its reach beyond cardiac patients to a healthy, active population—acquiring new clients with a referral-based service with strong retention benefits. The ability to combine cardiovascular insight with athletic performance data has transformed how the clinic supports long-term health and fitness, making VO2 Master central to its future plans.
- 150+ tests completed between September and year-end—entirely through word-of-mouth.
- Referrals snowball: local coaches now build VO₂ sessions into every training cycle.
- Retention boost: athletes book 3- to 4-month retests to verify gains, locking in long-term clinic revenue.
- Zero advertising spend, yet the service paid for itself twice over in the first 90 days.
