How can you match your in-exercise breathing to translate to real-world performance improvements? Well, you gotta track your V02. But most of the sophisticated equipment, hoses, and machines needed to measure this are built into labs that only the world's elite athletes can access. At least until now. 

The V02 Master Analyzer is an advanced mask and app system allowing everyday fitness enthusiasts as well as professionals to perform advanced VO2 measurements and tracking wherever they like to work out.


  • Accuracy
  • Portability
  • Quality


  • Price
  • Setup takes while
  • Initial learning curve

The mask works with an app to provide advanced, real time insights into a person's oxygen consumption and conservation during workouts. This allows you to make adjustments to your efforts to maximize performance.

Users can customize which metrics are displayed within the V02 Master App.

The aptly named V02 Master App can bring together more metrics than just those relevant to your breathing. It supports displaying and synchronizing data from additional sensors you may already have. This lets you view and customize all the data within one dashboard to really fine-tune your training and focus on the metrics that matter most to you specifically.

As your training progresses and your VO2 levels change, different user pieces (included) can be inserted into the mask, which help measure ventilation range at more precise levels.

  • Portability: The compact size and lightweight design of the VO2 Master make it easy to carry and use anywhere, whether in a gym, on a track, or outdoors.
  • Real-Time Feedback: The device provides immediate feedback on an individual's oxygen consumption, allowing for on-the-spot adjustments to training intensity and duration.

What Might Deter You From the VO2 Master:

  • Cost: This is a sophisticated piece of exercise tech and comes with a premium price tag ($6,295) VO2 Master is priced higher than traditional VO2 testing equipment, which may be a deterrent for budget-conscious individuals or organizations.
  • Initial Setup: The five-point headstrap takes some adjusting to achieve a perfect fit for initial use, however, from that point forward it is easy to take on and off. Same thing with the app. Initial setup will take awhile to customize the displays for your needs, but this is a one-time thing.
  • Learning Curve: While the device is user-friendly, some individuals may require training or guidance to use it effectively and interpret the data accurately.

The Thought Behind The Product:

Your VO2 max is a measure of the maximum amount of oxygen your body can use during intense exercise. It's a key indicator of aerobic fitness and is often used to assess an individual's cardiovascular endurance.

If you're tracking your V02 Max with a device like the V02 Master you can monitor changes in your oxygen consumption during workouts allowing you to tailor your training routine for optimal gains. You can identify how your oxygen consumption could be limiting your performance in a workout and begin to take steps to train in the right way to improve your VO2 levels.

Monitoring your V02 levels during workouts can help you optimize performance. 

For example, if your goal is to improve your endurance for a marathon, focusing on workouts that target your aerobic capacity, such as long-distance runs or interval training, can help increase your VO2 max over time.

Factors such as genetics, age, gender, and training status can influence your VO2 max. Even geography plays in (altitude and temperature can greatly improve or impede your V02 max training). While genetics play a significant role in determining your VO2 max potential, regular aerobic exercise is the most effective way to improve it. 

V02 max can be impacted by genetics and geography.
