Understanding Readiness Scores

Brief explanation of what each metric means

Updated January 16, 20252 min read

Readiness scores help Iridium adjust workout intensity based on your body's recovery status. The overall readiness score (0-100) combines multiple health metrics.

Key Metrics

HRV (Heart Rate Variability) - Measures your nervous system recovery. Higher values indicate better recovery. The app compares your current HRV to your baseline.

Resting Heart Rate - Lower is generally better. Elevated RHR can indicate fatigue or stress.

Sleep - Tracks duration and quality. Optimal sleep (8+ hours) supports better recovery and performance.

Muscle Recovery - Calculates recovery status for each muscle group based on training volume and time since last workout. Shows which muscles are ready for training.

Training Load (ACWR) - Acute-to-chronic workload ratio measures if you're training too much relative to your recent average. Values above 1.3 indicate high injury risk.

Cycle Phase (Women) - For female users, menstrual cycle phase affects performance and recovery. The app adjusts recommendations based on your current phase.

How It's Used

The readiness score influences workout generation:

  • High readiness (70+) - Suggests challenging workouts with higher volume
  • Moderate readiness (50-70) - Balanced workouts with moderate intensity
  • Low readiness (below 50) - Lighter workouts, active recovery, or rest days

The app automatically syncs health data from Apple Health when available, or you can manually input values.
