At D5 Health, we use the VO₂ Master Analyzer—the world’s first portable, lab-grade metabolic testing device—to give you precise insights into your fitness, metabolism, and overall health.
VO₂ Max Testing measures the maximum amount of oxygen your body can utilize during exercise. It’s the gold standard for evaluating cardiovascular fitness, endurance potential, and training effectiveness.
Basal Metabolic Rate (BMR) Testing measures the calories your body burns at rest. Knowing your BMR allows us to personalize your nutrition and optimize your energy balance for weight management, performance, or longevity.
Together, these tests provide a comprehensive picture of how your body uses oxygen and fuel—empowering us to create a customized plan for your health and performance goals.
