Why We Added VO₂ Max & Resting Metabolic Rate (RMR) Testing
No two bodies perform exactly the same, so why rely on estimates?
We believe the best decisions start with understanding your body. VO₂ Max and Resting Metabolic Rate (RMR) testing provide personalized data to help you train with purpose, fuel more effectively, and track meaningful progress over time.
THE BEST TRAINING PLANS START WITH DATA
Whether you’re training for a marathon, preparing for your next HYROX competition, chasing a new PR, or working toward better health, every goal starts with a plan.
The question is whether that plan is built on estimates or built on data.
Fitness watches, online calculators, and generalized training plans can provide a helpful starting point. But they don’t measure what makes your body unique.
That’s why we added VO₂ Max and Resting Metabolic Rate (RMR) testing.
These assessments measure how your body performs during exercise and how it uses energy at rest. The results help you make more informed decisions about your training, nutrition, and recovery.
WHY VO₂ MAX & RMR TESTING MATTER
No two people are exactly alike. Even people of the same age, height, and weight can have very different fitness levels, metabolisms, and training needs. That’s why averages can only take you so far.
VO₂ Max and RMR testing replace estimates with measurements specific to your body. Instead of wondering if your training or nutrition plan is working, you’ll have objective data to guide your decisions.
Those results become your baseline. As your fitness changes, you can measure your progress and adjust your training or nutrition plan based on real data instead of assumptions.
Whether your goal is improving endurance, enhancing athletic performance, managing your weight, or supporting your long-term health, understanding how your body works is one of the best places to start.
WHAT IS VO₂ MAX TESTING?
VO₂ max measures the maximum amount of oxygen your body can use during exercise.
In simple terms, it tells us how efficiently your heart, lungs, and muscles work together to deliver and use oxygen while you are active. The more efficiently your body uses oxygen, the greater your ability to sustain exercise over time.
VO₂ max has long been considered the gold standard for measuring cardiovascular fitness and endurance, but its value extends well beyond competitive athletics. Research continues to show that cardiorespiratory fitness is one of the strongest indicators of overall health and healthy aging. If you’re interested in learning more about the science behind VO₂ max, Harvard Health provides an excellent overview.
During your assessment, we also measure your ventilatory thresholds, allowing us to identify personalized training zones based on your body’s actual physiology rather than generalized heart rate formulas.
This information helps you:
- Train at the right intensity for your goals.
- Improve endurance more efficiently.
- Avoid spending too much time training too hard or not hard enough.
- Monitor improvements over time with objective data.
WHAT IS RESTING METABOLIC RATE TESTING?
Your Resting Metabolic Rate, or RMR, is the amount of energy your body uses each day just to keep you alive.
Even while you are sleeping, breathing, or sitting at your desk, your body is constantly using calories to support essential functions like breathing, circulation, and maintaining body temperature.
Many nutrition plans estimate your calorie needs using formulas based on age, height, weight, and activity level. While those calculations can provide a general guideline, they do not account for individual differences in metabolism.
Our RMR assessment uses indirect calorimetry, the clinical and scientific gold standard for measuring resting metabolic rate. Instead of relying on estimates, it measures your body’s actual calorie expenditure at rest and identifies whether your body primarily burns fat or carbohydrates for fuel.
Knowing this information provides a more accurate starting point for developing a nutrition plan that supports your individual goals, whether that’s weight loss, building muscle, improving athletic performance, or maintaining long-term health.
WHY WE RECOMMEND BOTH TESTS TOGETHER
Although these assessments measure different aspects of your health, they complement one another.
VO₂ Max answers the question:
How well does my body perform during exercise?
Resting Metabolic Rate answers the question:
How does my body use energy at rest?
Together, they provide a more complete understanding of how your body functions.
By combining both assessments, you will gain valuable insight into your cardiovascular fitness, personalized training zones, and daily energy needs. This can help you make more informed decisions about your workouts, nutrition, and recovery.
For those looking for the most complete picture of their health and performance, we recommend scheduling both assessments together. When booked as a bundle, you will also save compared to scheduling each test individually.
WHO CAN BENEFIT FROM TESTING?
Performance testing is not reserved for elite athletes.
These assessments can benefit anyone looking to better understand their body, including those who are:
- Beginning a new fitness journey.
- Training for a race or endurance event.
- Looking to lose weight.
- Building muscle or improving body composition.
- Returning to exercise after time away.
- Interested in improving their overall health.
- Looking for measurable benchmarks to track progress.
Whether you’re just getting started or have years of training experience, objective data can help you make more informed decisions and measure meaningful progress over time.
WHAT TO EXPECT
VO₂ Max and Resting Metabolic Rate (RMR) testing require different preparation, so we schedule them as separate appointments. That helps ensure the most accurate results.
Your RMR assessment measures how much energy your body uses while you’re at complete rest. To capture an accurate measurement, you’ll fast before your appointment and avoid caffeine, alcohol, and strenuous exercise beforehand.
Your VO₂ Max assessment measures how efficiently your body uses oxygen during exercise. Because you’ll perform a maximal exercise test, it’s important to arrive properly fueled, hydrated, and ready to give your best effort.
Before each appointment, we’ll send detailed preparation instructions and answer any questions so you know exactly what to expect.
After your assessment, we’ll cover the key takeaways with you before taking time to review your results in more detail. You’ll receive a personalized summary, and if you’d like to discuss your results further, we’re always happy to schedule time to meet with you.
READY TO STOP GUESSING?
Whether your goal is improving performance, supporting your health, or simply learning more about your body, VO₂ Max and Resting Metabolic Rate testing give you meaningful data to guide your decisions.
Book your VO₂ Max assessment, your RMR assessment, or bundle both together to gain the most complete picture of your health and performance.
