INSIGHTS STUDIO | ZONE 2 CARDIO
WHAT IS ZONE 2 (AND WHY IT MATTERS)
To improve your fitness, more cardio at maximal effort isn’t always the answer. For the majority of people, Zone 2 training, aerobic workouts at approximately 70%-80% of your maximal heart rate, can be an effective way to improve health, increase energy and enhance long-term athletic performance; without the need to push to exhaustion. In practical terms, Zone 2 effort is the pace at which you can still hold a conversation, but your body is exerting hard enough that you have to use fat as a primary fuel source, allowing you to make positive adaptations that can carry over to other workouts. Adding consistent Zone 2 training into your current workout routine can be a way to enhance your training program without accumulating excessive fatigue or risking burnout.
HOW YOUR BODY ADAPTS (AND WHAT THAT MEANS FOR YOU)
While there is no magic solution for health and exercise, Zone 2 training is an effective tool that can change how your body produces and uses energy. For many individuals, adaptations can include:
- Improved energy production (mitochondrial function): Your muscles becomes more efficient at creating energy from fat by using oxygen. Result: you feel more energized throughout the day and less dependent on quick energy spikes.
- Stronger cardiovascular system: Your heart becomes more efficient at delivering oxygen to working muscles. Result: you recover faster, feel less “winded,” and can handle higher-intensity efforts when needed.
- Improved aerobic base: You build a foundation that supports all other training. Result: strength training, classes and recreational activities feel easier and more manageable.
FOR MOST GYM-GOERS THIS MEANS
More consistent workouts and better recovery meaning you can exercise without feeling burned out. Zone 2 training is not as taxing on the nervous system as high-intensity interval or functional training.
A realistic, sustainable approach to staying active long-term. Zone 2 allows you to remain active and is suitable for almost all populations.
HOW TO KNOW YOU’RE IN THE RIGHT ZONE
One of the biggest challenges with Zone 2 training is accuracy. While many fitness wearables will estimate your heart rate zones and place Zone 2 at approximately 70-80% of your maximal heart rate, in the Insights Studio, we use direct metabolic testing to remove that guesswork and get your individualized heart rate zones and calorie utilization at each heart rate zone.
Using a VO₂-based ramp protocol, we can:
- Identify your exact heart rate ranges based on how your body uses fuel
- Show where you transition between effort zones
- Provide clear, personalized targets for your training
These are key takeaways that allow you to optimize your training time and maximize your results.
WHERE TO START
If you’re looking to build consistency in your aerobic workouts, improve energy and support long-term health, Zone 2 is one of the most valuable places to begin. Sessions can include bouts of cardio on the treadmill, stair climber, exercise bike or any preferred modality as long as you are able to monitor and adjust your intensity levels to allow your body to respond.
If you’re unsure what that should look like for you, the Insights Studio can help you define it clearly: and give you a plan you can actually follow. Schedule an Active Metabolic Rate test to determine your individual heart rate zones and learn how you can use the data to improve your workouts.
