Wearables Estimate. This Test Measures.
Your watch offers a useful estimate. A VO₂ Max test reads aerobic capacity directly, tracking how fast your body pulls in oxygen and turns it into fuel while the effort climbs.
The result is a clear picture of how you handle hard work, the point where fatigue takes over, and the system with the most room left to grow.
Whether you are training for the Peachtree Road Race, riding loops through Dunwoody, or logging BeltLine miles, a measured number gives every session a purpose.

Few single measures predict all-cause mortality as strongly as VO₂ Max. It reflects how well your heart, lungs, and blood deliver oxygen to working muscle, and it gives you a clear target to move.

Built for Everyone, Not Just Athletes
VO₂ Max often gets filed under marathoners and competitive cyclists. It carries the same weight when you are getting back into shape or want a clear starting point.
Returning after time off, staying fit through a long, hot Atlanta summer, or chasing a new personal record, your aerobic capacity shows you where to begin.
The goal is not a score to show off. It is a clear view of where you are today and what to focus on next.

Your Questions, Answered
What does a VO₂ Max test measure, and how does it feel?
VO₂ Max is the size of your aerobic engine: the most oxygen your body can take in and convert to energy. You run on a treadmill or ride a bike as the workload steps up, while a mask compares the oxygen you breathe in with the CO₂ you breathe out.
Your oxygen use rises with the effort until it stops climbing. That ceiling is your VO₂ Max, reported in ml/kg/min. Elite endurance athletes reach around 80 ml/kg/min, and sled dogs go beyond 200.
How long does a VO₂ Max test take at DexaFit Atlanta?
Plan on about 35 minutes at our Chamblee location. The test itself takes roughly 15 minutes. Skip food for about 3 hours beforehand. Results are instant, so you go over them the same visit and leave with a full report to revisit as your fitness changes.
How is VO₂ Max linked to how long and how well I live?
VO₂ Max reflects cardiovascular health more closely than almost any other single number. In a study of 122,007 people, the least-fit quintile died at roughly 5 times the rate of the most-fit quintile (Mandsager et al., JAMA 2018). VO₂ Max responds to training at every age, so lifting it supports both a longer life and a stronger one.
How do I improve my VO₂ Max over time?
Build most of your week on easy aerobic (Zone 2) sessions and add one or two hard interval workouts. That mix raises VO₂ Max steadily and supports your heart and metabolism along the way. Testing first gives you a starting point, so each gain shows up as a measured change.
What is Zone 2, and how do I find mine?
Zone 2 is steady, conversational aerobic effort, usually around 60 to 75% of your maximum heart rate. It grows your aerobic base and your capacity to burn fat, and it works best alongside occasional hard efforts. Your VO₂ Max test pinpoints your own Zone 2 range from measured data instead of an age formula.
What happens while I am on the treadmill or bike?
You begin at an easy pace on a treadmill or bike, and the workload climbs in stages toward your peak. A mask reads your oxygen and CO₂ the whole way, and a DexaFit Atlanta specialist stays beside you from warm-up to finish.
What will I learn from my VO₂ Max results?
Your report shows your VO₂ Max, your aerobic and anaerobic thresholds, your individual heart-rate zones and Zone 2 range, how you use fat and carbohydrate as fuel at different efforts, and how efficiently you breathe. DexaFit ai then translates those numbers into a clear estimate of your biological age.
