Interpret Your Exercise Readiness Score

What each readiness level means, what color it appears in, and how to choose your training intensity for the day.

Last updated2026-09-13

Interpret Your Exercise Readiness Score

The readiness score maps to five levels. Each level carries a color, a short description, and a suggestion for training intensity. Use them as a daily guide — not as rigid rules.

The Five Levels

Excellent (above 95%) — Purple

Your body is well recovered and ready for demanding sessions. This is a good day for intervals, tempo work, or longer endurance efforts.

High (75%–94%) — Blue

Recovery is solid. You can handle most types of training, including moderate-to-high intensity. A good day for a solid workout.

Moderate (50%–74%) — Green

Your readiness is balanced. Keep training within your usual range. Steady-state or technique-focused sessions work well today. Avoid unnecessary spikes in load.

Low (25%–49%) — Yellow

Recovery is lagging. Avoid high-intensity work. Choose low-intensity aerobic activity, active recovery (such as a light walk or gentle stretching), or take a rest day.

Poor (below 25%) — Red-Orange

Your body is showing signs of significant fatigue. Prioritize rest and recovery. If you do train, keep it very light.

How to Use the Score

  1. Check before you plan. Look at your readiness score before deciding on today's workout intensity.
  2. Match the level to the session. Higher scores invite harder efforts; lower scores call for lighter work.
  3. Watch the trend, not just today's number. A single low score after a hard week is normal. A sustained downward trend deserves more attention.
  4. Combine with how you feel. The score is based on heart-rate data. It does not know about your stress, sleep quality last night, or how your muscles feel right now. Your own judgment matters.

What Low Scores Do Not Mean

A low readiness score is not a warning that something is wrong with your health. It simply means your recent training load has been high relative to your established baseline. This is a normal part of training — hard blocks push the score down, and recovery blocks let it rebuild.

The goal is not to stay at 100%. The goal is to train with awareness.

What High Scores Do Not Mean

A high readiness score does not mean you should always train hard. It means your body has capacity today. You can still choose a moderate session — especially if your weekly plan includes variety.
