Why We Use MyZone and Why We Train in Zones

Train smarter, not just harder—with benefits that go far beyond endurance.

If you’ve ever worn a MyZone heart rate monitor in one of our sessions at ThriveFit, you’re probably familiar with the green zone. That’s Zone 2—where your heart rate sits at about 60–70% of your maximum heart rate. It’s the zone where you can still carry on a conversation, but you’re definitely working. And while it might feel “easy” compared to red-line sprints or high-intensity intervals, Zone 2 training is where some of the most powerful long-term fitness benefits happen.

Whether you’re training in Nocatee, Ponte Vedra Beach, or a neighborhood nearby, Zone 2 training deserves a spot in your fitness routine.

Improved Endurance and Aerobic Capacity

Zone 2 training builds a strong aerobic base—the foundation of your cardiovascular fitness. It helps you go longer with less fatigue, making your workouts more sustainable and your recovery faster.

Enhanced Cardiovascular Health

Spending time in Zone 2 strengthens your heart muscle, helps regulate blood pressure, and improves circulation—critical components of a longer, healthier life.

Efficient Fat Burning for Fat Loss

In this zone, your body primarily uses fat for fuel instead of carbohydrates. Over time, this helps boost metabolic health and support fat loss, especially when combined with strength training and balanced nutrition.

Increased Mitochondrial Function

Zone 2 workouts increase both the number and efficiency of your mitochondria—the energy-producing engines of your cells. More mitochondria means more energy and better performance across the board.

Reduced Risk of Injury and Overtraining

Because it’s lower impact and lower stress on your joints and nervous system, Zone 2 is safer and easier to recover from than higher-intensity work. That means you can train more consistently without burning out.

Improved Insulin Sensitivity

Moderate-intensity cardio helps your body regulate blood sugar more effectively—key for preventing and managing conditions like insulin resistance and type 2 diabetes.

Enhanced Mental Health

Like all movement, Zone 2 boosts your mood, helps manage stress, and supports better sleep. The steady-state rhythm can be especially grounding and meditative.

Easier to Stick With

Zone 2 is enjoyable and accessible for most people. It doesn’t leave you gasping for air, so you’re more likely to build a habit and keep it. Consistency wins over intensity, every time.

The Bottom Line

Whether you’re new to fitness or looking to level up your personal training experience in Nocatee or Ponte Vedra Beach, adding Zone 2 training to your mix will help you improve endurance, accelerate fat loss, and stay consistent year-round. It’s the perfect complement to strength training, especially when programmed by the expert coaches at your local gym.
