You train. You track. But sometimes progress stalls and the reason isn’t obvious. Biometryx brings your health and performance metrics together to estimate your Biological Age and highlight the systems that may need attention. Instead of looking at dozens of disconnected metrics, Biometryx helps you see the bigger picture. How Biometryx Works Biometryx analyzes signals from multiple health systems: • Cardio fitness • Metabolic health • Muscle performance • Recovery & sleep Using metrics such as: • VO₂ Max • Resting heart rate • HRV • Sleep duration and deep sleep • Strength performance • Body measurements • Blood biomarkers Each system is analyzed individually and then combined into an overall Biological Age estimate so you can understand where you currently stand. Your Health, Broken Down Clearly Biometryx helps you identify which systems may be holding you back. You’ll see: • Your Biological Age estimate • Cardio Age based on endurance and heart metrics • Metabolic Age based on body composition and biomarkers • Muscle Age based on strength performance • Recovery Score based on sleep and recovery signals Turn Insights Into Action Biometryx analyzes your metrics and provides AI-generated insights designed to help you better understand your data. These insights highlight patterns across your metrics and suggest areas that may deserve attention in your training, recovery, or lifestyle habits. Track Your Progress Health improvements take time.
