The best indication of cardiovascular fitness, designed to measure how efficiently your bosy uses oxygen during exercise.
Smartwatches estimate VO2 Max using heart rate, age, and activity data - providing a useful estimate but inaccurate measure of your fitness.
A true VO2 Max test uses specialised equipment to directly measure how much oxygen your body consumes during intense exercise. By analysing your breathing and oxygen uptake in real time, it delivers a far more accurate and reliable assessment of your fitness.

You'll run on a treadmill for 10–15 minutes, with intensity gradually increasing.
You'll wear a mask connected to our system to measure your breathing and oxygen use, while your heart rate is monitored throughout to assess your cardiovascular response.
Our VO₂ Max test can be performed on a stationary bike or treadmill.
Cycling results are typically 7–18% lower, as running engages more muscle groups. For experienced cyclists, a bike test offers more relevant results, while non-cyclists are better suited to a treadmill test.
We use a Zwift Ride with a Wahoo Kickr Core 2 for a smooth, accurate testing environment.

The most advanced VO2 Max equipment, complemented with our innovative software.
We’re the UK’s leading provider of longevity scans, with over 41,000 scans completed.
Highly detailed reports built from the most precise and relevant datasets - setting a new industry standard for fitness testing.
Easy-to-understand results that help you make informed decisions and confidently progress your fitness.
Your results will clearly show your current fitness level, a breakdown of your heart rate, VO2 Max rate and Calories burnt per hour across your aerobic and anaerobic thresholds, and the rate at which your heart rate recovers over 2 minutes.
You will also get a breakdown of your training zones. This gives you clear information about how many Calories you burn at what heart rate, as well as the speed and incline of the treadmill to achieve that — enabling you to better target your workouts to reach your goals.

Improve your VO2 Max with regular HIIT (High-Intensity Interval Training), alternating short bursts of intense effort with lower-intensity recovery. Your report identifies your aerobic and anaerobic thresholds, so you can accurately set both training zones.
Alongside 2–3 HIIT sessions per week, add a longer, steady cardio session.
We'll provide your exact heart rate zones and personalised guidance based on your results to help you train effectively.
