Apple Watch Cardio Fitness – Why It Matters

One of the most valuable features is Apple Watch cardio fitness tracking, which measures your VO₂ max. This metric reflects how efficiently your body uses oxygen during exercise—a key indicator of cardiovascular health.

• What it means: Higher VO₂ max = stronger endurance and better heart health.
• Why it matters: Low cardio fitness has been linked to increased health risks.
• How Apple Watch helps: The watch uses your heart rate and activity data to estimate your score and notifies you if your fitness is below average.

If you’re looking for something more budget-friendly, Fitbit provides a solid range of fitness features, but it falls short when compared to Apple’s premium ecosystem and advanced capabilities.
