VO2 Max and RMR Testing
Experience the Gold-Standard in Metabolic Testing
We offer VO2 Max and Resting Metabolic Rate (RMR) testing to deliver precise insights into your fitness, metabolism, and longevity potential—helping you train smarter, eat better, and perform at your peak.
Book TestWhat Is VO2 Max Testing?
VO2 Max measures your body’s ability to use oxygen during intense exercise and is considered the gold standard for cardio-respiratory fitness and measuring your potential for longevity.
The higher your VO2 Max, the more oxygen your body can utilize, translating into greater energy production and performance potential.
Key Benefits of VO2 Max Testing
- Understand Your Fitness Level: See where you stand compared to your peers.
- Optimize Training: Tailor workouts based on your aerobic and anaerobic thresholds.
- Track Progress: Monitor improvements over time to ensure effective training.
- Enhance Performance: Maximize endurance and uncover untapped potential.


What Is RMR Testing?
Your Resting Metabolic Rate (RMR) is the number of calories your body burns at rest to maintain essential functions such as breathing, digestion, and circulation.
RMR testing gives you a clear picture of your daily caloric needs, helping you design a nutrition plan that aligns with your goals.
Key Benefits of RMR Testing
- Personalized Nutrition: Accurately calculate your daily calorie requirements.
- Boost Weight Management: Use RMR data to create a sustainable plan for weight loss, maintenance, or muscle gain.
- Improve Metabolic Health: Understand how your body uses energy to fuel better dietary choices.
