One score that fuses VO₂ max, heart rate variability, and recovery into a heart health narrative.

Cardiovascular fitness is one of the strongest predictors of healthspan, so Metric treats it as a headline metric. The Cardio Health Score brings VO₂ max, resting heart rate, HRV, respiratory rate, and recent training load together to show how resilient your heart and lungs are today.

Why it matters

Research from the American Heart Association shows that small improvements in cardiorespiratory fitness can reduce all-cause mortality risk by double digits. The Cardio Health Score helps you identify which lever—more zone two work, better sleep hygiene, stress management, or recovery—will deliver that improvement fastest for you.

• Score details reveal how each input moved the needle compared with your personal baseline.
• Historical charts expose seasonal swings, making it easy to compare training blocks or travel stretches.
• Cortex suggestions recommend the right mix of conditioning, strength, and recovery sessions when your score dips.
• Community comparisons show how your progress stacks up against peers pursuing similar goals.

Turning insight into action

When the score highlights falling HRV, Metric nudges you toward restorative movement and breathwork. If VO₂ max climbs, the dashboard celebrates the win and suggests maintenance strategies. Everything is there to help you make informed trade-offs between intensity and recovery.

Recommended check-in cadence 2-3 times per week. That is how often most members review the score to stay ahead of stress and overtraining.

Whether you are training for a marathon or reclaiming lost fitness after an injury, the Cardio Health Score keeps your heart front and centre and shows exactly how today’s habits shape tomorrow’s resilience.
