VO₂ Max Explained and How to Improve It

If you want a clear way to measure your cardiovascular fitness, VO₂ max is one of the most powerful metrics available.

VO₂ max measures how much oxygen your body uses during exercise and is associated with better physical fitness, lower cardiovascular disease risk, and increased longevity.¹

More importantly, it’s something you can improve with structured training and the right equipment.

What Is VO₂ Max?

VO₂ max stands for maximal oxygen uptake — the maximum amount of oxygen your body can use during exercise.¹

During exercise, your body delivers oxygen to your muscles, where it’s used to produce energy. The more efficiently this system works, the higher your VO₂ max.¹

It’s a clear, objective indicator of your cardiovascular fitness.¹

Why VO₂ Max Matters

VO₂ max matters because it reflects how efficiently your body supports sustained movement and overall health.¹

A higher VO₂ max is associated with:

• Lower risk of cardiovascular disease

• Reduced risk of chronic conditions like diabetes and stroke

• Improved overall fitness and longevity¹

It’s also closely linked to endurance performance.³

How NordicTrack Helps Improve VO₂ Max

Improving VO₂ max comes down to one thing: training at the right intensity, consistently.

That’s where your equipment and programming make a difference.

NordicTrack equipment and iFIT can help you consistently train at the intensity required to improve VO₂ max.

On a NordicTrack treadmill:

• Incline automatically adjusts to increase training intensity

• Speed changes to match structured interval workouts

• Cushioned decks support more consistent, lower-impact training

On NordicTrack bikes and ellipticals:

• Resistance adapts to match effort levels

• Trainer-led intervals guide you into higher-intensity zones

• Smooth motion supports longer, sustained aerobic sessions

On a NordicTrack treadmill like the Commercial 1750, incline and speed automatically adjust to match trainer-led interval workouts.

Train Smarter with iFIT

iFIT removes the guesswork from improving VO₂ max by guiding your intensity for you.

SmartAdjust: Automatically adjusts speed, incline, or resistance based on your past workouts, helping you progress over time.

ActivePulse: Uses heart rate data to keep you in the right intensity zone, which is key for improving aerobic capacity.

Follow Trainer: Automatically matches your machine to the trainer’s workout so you hit the intended effort without guesswork.

This combination helps you consistently train at moderate to vigorous intensity – the range shown to deliver the greatest cardiovascular benefit.²

The Most Effective Way to Improve VO₂ Max

High-intensity interval training (HIIT) is one of the most effective ways to improve VO₂ max.³

Many iFIT programs are built around this structure:

• Short bursts of higher intensity

• Recovery periods between efforts

• Repeated intervals that challenge your cardiovascular system

Even a few weeks of structured interval training can lead to measurable improvements.³

Ready to level up your VO₂ max? Try these iFIT Series

These series include dedicated interval and speed sessions designed to challenge aerobic capacity:

• Train Like A Pro: Sanya Richards-Ross Includes structured 400m interval blocks that align with interval training methods shown to improve VO₂ max.³

• Parthenon Running Series Features repeated 30-second VO₂ max intervals with equal recovery – a classic high-intensity structure for improving oxygen uptake.

• 5K Training Series: Vietnam Blends steady-state and interval sessions to progressively build aerobic base and speed.

• 10K Training Series: Slovenia A periodized program combining pillar workouts, recovery runs, and long runs to improve endurance and cardiovascular efficiency.

• Iberian Fast and Fit Series Alternates tempo, interval, and steady-state runs to improve VO₂ max and lactate threshold.

A Smarter Way to Train

VO₂ max isn’t just a number. It’s a measurable reflection of how efficiently your body performs during effort.

With NordicTrack and iFIT, you don’t have to guess how to improve it.

Your equipment adjusts.Your workouts are guided.Your progress builds over time.

Choose a structured program, stay consistent, and build measurable aerobic progress over time.
