VO2 Max Test in Nashua, NH
Maximize Your Fitness Potential
Get a VO₂ Max Fitness Test to assess your cardiovascular fitness, and get heart rate zones built from your own data instead of an age-based formula.
What you’ll learn
Your VO₂ Max. The most widely used measure of cardiovascular fitness, and one of the strongest predictors of longevity.
Your heart rate zones. Personalized training zones, including your true Zone 2 range.
Your thresholds. The intensities where your body shifts toward harder, less sustainable effort.
Your fuel use. How much you burn fat versus carbohydrate at different intensities.
Your biological age. How your fitness compares to your chronological age.
Why it matters
VO₂ Max is one of the strongest predictors of how long, and how well, you'll live. Large studies have found that low cardiovascular fitness carries a mortality risk comparable to smoking, diabetes, or heart disease.
It also declines with age, typically around 10% per decade after 30. That decline is what eventually makes everyday things harder: climbing stairs, carrying groceries, keeping up with kids or grandkids.
The good news is that VO₂ Max is highly trainable at any age. Knowing your number, and the heart rate zones that move it, means you can train with purpose instead of guessing.
Who it’s for
VO₂ Max testing used to be reserved for elite athletes. Now it's available to anyone 18 or older, whether you're training for a race, stuck at a plateau, or just want to know where your cardiovascular health stands.

Roland B.
What a great experience. I had a DEXA body composition scan and tested my VO2 max on their treadmill. The facility was super clean and comfortable. The owners were extremely kind, professional, and helpful. Camille went over the results with me at the end and I left feeling encouraged and motivated to continue the work I’ve been doing toward my goal of aging well with a health span that matches my life span. I highly recommend DEXAFIT Nashua!

FAQs
-
VO₂ Max is the maximum amount of oxygen your body can take in, deliver, and use during intense exercise. Think of it as the size of your aerobic engine. It reflects how well your lungs, heart, blood vessels, and muscles work together.
As you exercise harder, your oxygen use climbs. Eventually it levels off, even as you keep pushing. That plateau is your VO₂ Max.
Results are reported in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min), so you can compare across people of different sizes. Many recreational exercisers score somewhere in the 30s to 40s. Elite endurance athletes can reach the 80s.
A higher VO₂ Max means a bigger aerobic engine. That supports better endurance, better health, and more capacity for daily life as you age.

During a VO₂ 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 CO₂ output, providing data on your aerobic capacity. The test is designed to safely determine your fitness level under careful monitoring.
-
Zone 2 is steady, moderate effort, slow enough that you can still hold a conversation. It builds your aerobic base by training your body to use oxygen and burn fat more efficiently. That's the foundation of endurance and long-term cardiovascular health. Think of a brisk walk uphill, an easy jog, or a steady bike ride, usually for 30 minutes or more.
HIIT (High-Intensity Interval Training) alternates short bursts of hard effort with recovery, like 30 seconds of sprinting followed by a minute of walking. It's one of the most direct ways to raise your VO₂ Max.
Most people get the best results from both. A common approach is to spend most of your training time in Zone 2 and a smaller portion at high intensity.
Your VO₂ Max test identifies your personal Zone 2 range from your own data. Generic formulas based on age or max heart rate can be off by a wide margin. Training in the right zone is what makes Zone 2 work.
