Knowing when to push hard and when to back off is one of the most challenging aspects of training effectively. Garmin’s Training Readiness feature provides a sophisticated solution to this age-old athletic dilemma, offering a precise, personalized assessment of your body’s current state to help maximize training efficiency and results.

What is Training Readiness?

Training Readiness is a comprehensive metric designed to give you actionable insights about your body’s preparedness for training stress. Rather than relying solely on feel or guesswork, this top-line feature analyzes multiple physiological and lifestyle factors to help you determine when your body is primed for challenging workouts and when recovery should take priority.

The feature provides a simple-to-understand classification system, categorizing your readiness as:

  • Prime: Optimal state for challenging workouts
  • High: Well-prepared for moderate to intense training
  • Moderate: Ready for standard training sessions
  • Low: Some limitations present; consider lighter workouts
  • Poor: Recovery should be prioritized over intense training

Beyond the basic classification, checking the Training Readiness widget reveals your current numerical score and a breakdown of how various underlying factors have contributed to your current state.

How Training Readiness is Calculated

Garmin’s Training Readiness doesn’t rely on a single data point but instead uses a multi-layered analysis that combines activity metrics with lifestyle factors. The primary components include:

1. Sleep Score (0-100)

Your sleep score reflects not just duration but quality, based on:

  • Total sleep time
  • Sleep stage distribution (deep, light, REM)
  • Recovery activity in your autonomic nervous system (measured via heart rate variability)

This score compares your sleep patterns against standards established by sleep science organizations to determine how effectively your body is recovering overnight.

2. Recovery Time

This countdown timer shows when your body can be expected to fully recover from your last activity. Initial recovery time is calculated based on:

  • The intensity and duration of your most recent workout
  • Any remaining recovery time from previous activities

The countdown can be dynamically adjusted based on:

  • Sleep quality improvements or deficits
  • Daily stress levels
  • Physical activity outside of structured workouts

3. Acute Training Load

This metric evaluates whether your recent training volume is:

  • Optimal: Sufficient to maintain or improve fitness
  • Excessive: Potentially compromising performance or increasing injury risk
  • Insufficient: Not enough stimulus to maintain current fitness

Each workout’s impact gradually decreases over a 10-day window, providing a rolling assessment of your short-term training stress.

4. HRV Status

Heart Rate Variability (HRV) provides insight into your autonomic nervous system function:

  • Balanced: Your 7-day average HRV falls within your personal baseline range
  • Unbalanced: HRV falling outside your normal range, potentially indicating:
    • Inadequate recovery
    • Excessive workloads
    • Alcohol consumption
    • Immune system activation (fighting illness)

5. Sleep History

While a single good night’s sleep is beneficial, it doesn’t immediately erase a sleep deficit. This factor considers your sleep quality over recent days, not just the previous night.

Additionally, exceptionally long periods of wakefulness before your most recent sleep (e.g., 20+ hours) can negatively impact readiness regardless of sleep quality.

6. Stress History

Using all-day stress tracking, this metric factors in your stress levels over the past three days while awake. High stress—whether physical, mental, or emotional—requires energy resources that might otherwise support training adaptation.

How Training Readiness Changes Throughout the Day

Your Training Readiness score isn’t static but updates dynamically throughout the day:

  • Morning update: The most substantial adjustment happens when you wake up, incorporating your sleep score, HRV status, and overnight recovery
  • Ongoing updates: The score continues to evolve throughout the day:
    • Increasing as recovery time expires
    • Decreasing after recording activities (with intensity determining the magnitude of the decrease)
    • Adjusting based on stress levels and other factors

This dynamic nature makes Training Readiness an excellent tool for making real-time decisions about your workout plans.

Training During Low Readiness Periods

A low Training Readiness score doesn’t necessarily mean you should skip exercise entirely. In certain training paradigms, such as block training, deliberately training through periods of lower readiness is part of the approach—creating an overload stimulus followed by extended recovery.

If using such a training model, pay attention to which factors are driving your lower readiness:

  • If primarily due to high acute training load and longer recovery times, this aligns with the deliberate overload approach
  • If driven by poor sleep history or high stress, you might want to reconsider your training plan

Remember that Training Readiness is just one perspective to guide your training. Always integrate this data with subjective feelings and the broader context of your training plan.

Training Readiness vs. Performance Readiness

An important distinction exists between training readiness and performance readiness. Your Training Readiness score on race morning isn’t necessarily predictive of your performance potential.

Many elite athletes report poor sleep before major competitions yet still achieve personal bests. Pre-race anticipation can elevate stress levels without negatively impacting performance.

Training Readiness is designed to optimize your day-to-day training decisions, focusing on:

  • Balancing strain and recovery
  • Promoting good sleep habits
  • Maintaining homeostatic balance
  • Improving performance capacity over time

Race-day performance is more about executing your abilities rather than building them—a different physiological context than regular training.

Compatible Garmin Devices

Training Readiness is available on select Garmin devices, including:

  • Forerunner 955, 965, and 970 series
  • Fenix 7 and 8 series
  • Epix (Gen 2 and newer)
  • Enduro 2
  • And other premium Garmin watches with advanced training metrics

To access all contributing factors, your device should support features like:

  • Advanced sleep tracking
  • All-day stress monitoring
  • HRV status
  • Training load metrics

Making the Most of Training Readiness

To optimize your training using this feature:

  1. Check first thing in the morning to plan your day’s training approach
  2. Review contributing factors to understand what’s driving your score
  3. Consider the context of your broader training plan
  4. Make appropriate adjustments to intensity, duration, or workout type
  5. Track patterns over time to identify lifestyle factors that consistently impact your readiness

By making data-informed decisions about when to push and when to prioritize recovery, you can maximize adaptation while minimizing the risk of overtraining or injury.
