What is VO Max?

VO Max measures the milliliters of oxygen you use per kilogram of body weight in one minute. If someone has a VO Max of "50" (fully expressed as "50 mL/kg/min"), it means their maximum oxygen consumption in one minute is 50 milliliters per kilogram of bodyweight. Data has shown that VO Max is not only a powerful marker of overall cardiorespiratory fitness but also one of the best predictors we have of all-cause mortality.

It also helps you figure out the best heart rate zones for your workouts, including Zone 2 training, for a well-rounded and effective routine.

Longevity and Lifespan

Improving how we exercise is one of the most powerful ways to support long-term health. Among all metrics, VO₂ Max stands out as one of the strongest predictors of lifespan — offering direct insight into your cardiovascular fitness, vitality, and how well you’re aging.

But we don’t stop there.

Our AI-powered platform goes beyond individual test results to deliver a deeper layer of understanding: your biological age. By analyzing your VO Max, RMR, and body composition data, our system calculates how old your body is functioning compared to your actual age.

This gives you a single, powerful number — backed by science — that reflects your true physiological condition.

With this insight, you can personalize your fitness, nutrition, and recovery strategies not just to feel younger — but to live younger, longer.

Step 1: Get ready and warm up

To begin, we'll secure a special mask on you and a heart rate monitor for the VO Max test. Then we’ll warm up on a treadmill.

What to expect

Step 2: Increase intensity

During the test, the difficulty (via incline) will slowly increase until you can no longer continue. Our system will monitor how much oxygen you use and how much CO you produce.

Step 3: Receive help from an expert

After the test, you'll receive a detailed analysis of your performance, which will provide valuable information about how efficiently your body uses oxygen during exercise and other important insights.

FAQs

  • Picture your body as a high-performance vehicle in an endurance race, where your VO max symbolizes the size and efficiency of its engine, specialized in oxygen usage. This test is about measuring your body's ability to take in oxygen, transport it through your bloodstream, and use it in your muscles to create energy at peak exertion.

    For instance, if you're jogging leisurely, you might use around 2 liters of oxygen per minute. Increase your pace, and this consumption goes up. At a fast, challenging pace, you might hit 4 liters per minute. But then, you reach a point where, despite pushing harder, your oxygen usage plateaus. This plateau is your VO max.

    During a VO max test, you'll typically engage in an activity like running on a treadmill or cycling, with the intensity gradually increasing. Wearing a mask connected to a device, your oxygen intake and carbon dioxide output are measured. The objective is to push you to your limit to find where your oxygen consumption peaks.

    Let's say your VO max result is 43 ml/kg/min. This indicates the maximum amount of oxygen your body can use per minute for each kilogram of body weight during intense exercise. It's a benchmark of your aerobic capacity. For context, elite athletes like Lance Armstrong have recorded VO max levels around 84 ml/kg/min, whereas sled dogs, known for their incredible endurance, can reach a VO max of over 200 ml/kg/min.

    Your VO max score isn't just about speed; it’s more about the power of your aerobic engine. A higher VO max indicates a greater potential for endurance performance, much like a car with a bigger engine potentially going faster.

  • A high VO Max is crucial not just for athletic performance but also for your overall health and longevity. It's a key indicator of your cardiovascular health, with a direct correlation to reduced risks of chronic diseases and lower all-cause mortality rates. Improving your VO Max can significantly enhance your quality of life, allowing you to maintain an active lifestyle as you age.

  • Improving your VO Max through targeted training like high-intensity interval exercises can lead to numerous health benefits. Enhanced VO Max improves your body's efficiency in using oxygen, which is vital for endurance and overall fitness. Regular training adapted to boost your VO Max also contributes to better heart health, reduced risk of chronic diseases, and improved metabolic function.

  • Zone 2 training involves moderate-intensity aerobic exercise, typically maintained at 60-75% of your maximum heart rate. This level of intensity is where your body maximizes fat oxidation and improves aerobic capacity. An example of a Zone 2 workout could be a steady, moderate-paced run, cycle, or swim where you can comfortably hold a conversation.

  • While Zone 2 training focuses on sustained, moderate intensity to improve endurance and efficient oxygen use, High-Intensity Interval Training (HIIT) contrasts sharply with its structure. HIIT involves short bursts of intense exercise followed by rest or low-intensity periods. For instance, a HIIT session might include 30 seconds of sprinting followed by a minute of walking, repeated several times. HIIT is designed to improve anaerobic capacity and metabolic rate.

    Zone 2 training is recommended for building a strong aerobic base, vital for long-term cardiovascular health and endurance. HIIT, on the other hand, is excellent for boosting metabolic health and improving strength and power. Balancing these two types of workouts can lead to a well-rounded fitness profile, catering to both endurance and strength aspects of physical health.

  • During a VO Max test, you'll perform a graded exercise test on a treadmill or bike, starting at low intensity and gradually increasing to your maximum effort. You'll be fitted with a mask that measures your oxygen consumption and CO output, providing data on your aerobic capacity. The test is designed to safely determine your fitness level under careful monitoring.

  • The VO Max test is ideal for anyone interested in optimizing their fitness, from amateur exercisers to elite athletes. It’s especially beneficial for those looking to tailor their exercise programs to specific health or performance goals, or for anyone curious about their cardiovascular fitness level.

  • Absolutely. Understanding your VO Max can be a game-changer for those struggling with weight loss or a fitness plateau. Tailoring your workout intensity based on VO Max data can lead to more effective exercise sessions, helping break through barriers and achieve desired results.

  • From the VO Max test, you will gain a comprehensive understanding of various crucial aspects of your fitness and health, including:

    Aerobic Capacity: The primary outcome, VO Max, is a measure of the maximum amount of oxygen your body can utilize during intense exercise. It's a definitive indicator of your cardiovascular fitness.

    Aerobic and Anaerobic Thresholds: The test identifies at what point your body switches from aerobic (oxygen-using) to anaerobic (oxygen-lacking) metabolism during exercise. This helps in optimizing training intensity for endurance and performance.

    Energy Utilization: Understand how your body uses different energy sources (fats and carbohydrates) at various exercise intensities. This insight is crucial for tailoring diet and exercise plans.

    Heart Rate Zones: The test delineates your unique heart rate zones, allowing for more precise and effective training regimens, especially for endurance sports.

    Respiratory Efficiency: Gain insights into how efficiently your lungs transfer oxygen to your blood and how effectively your muscles use that oxygen.

    Beyond these fundamental metrics, our advanced AI technology takes the data analysis a step further. It synthesizes your test results to provide a simple yet profound metric: your biological age.

    This AI-derived insight offers a clear picture of your overall health and fitness in relation to your chronological age, giving you a more comprehensive understanding of your body's true condition and potential areas for improvement. With this knowledge, you can tailor your lifestyle, exercise, and nutrition plans to not just meet, but exceed, your health and fitness goals.
