Garmin Training Load Planner Calculator
Plan a target acute load, load ratio, and approximate workout load budget from the numbers shown on your compatible Garmin device. The tool explains where Garmin's proprietary calculation ends and this planning estimate begins.

What Does Garmin Training Load Mean?
Garmin training load estimates the physiological impact and recovery demand of recorded exercise. It is based on excess post-exercise oxygen consumption, called EPOC.
Garmin describes exercise load as the impact of one activity. Acute load combines recent activities with a weighted moving average. A new activity enters at full value, then its effect fades during the next 10 days and is normalized to a 7-day view.
Chronic load is a weighted average of acute load scores over 28 days. Load ratio equals acute load divided by chronic load. Garmin Support currently lists 0.8 to 1.5 as the fixed optimal load-ratio range.
Why Can't You Add Seven Garmin Exercise Loads?
Garmin states that acute load is a weighted sum, so it cannot be calculated by adding recent activity load values. Older devices may show a simpler 7-day view, which can differ from newer devices.
This planner uses your displayed Garmin acute load as the starting point. It never labels a simple workout sum as an exact future Garmin acute load.
How Does the Garmin Training Load Planner Work?
The planner selects a target ratio inside Garmin's 0.8 to 1.5 optimal band. It multiplies that ratio by chronic load to estimate a target acute load.
| Planning goal | Target ratio | Use |
|---|---|---|
| Recovery bias | 0.85 | Lower recent strain while staying inside the Garmin band. |
| Maintain | 1.00 | Keep acute and chronic load near the same level. |
| Gradual build | 1.20 | Plan a moderate rise above long-term load. |
| Upper optimal band | 1.40 | Plan near the upper part of Garmin's band with more caution. |
The new-load budget equals target acute load minus projected acute load after the decay assumption. This is only a planning estimate. Actual Garmin decay depends on when each activity occurred and how Garmin weighs it.
Garmin Training Load Planning Examples
A load ratio needs context. The same ratio can lead to different plans when acute load, chronic load, recovery, and workout type differ.
An acute load of 300 and chronic load of 500 gives a ratio of 0.60. A recovery or maintain plan can rebuild load without jumping to the top of the band.
An acute load of 620 and chronic load of 580 gives a ratio near 1.07. A gradual build target can add a modest budget across planned sessions.
An acute load of 1,050 and chronic load of 650 gives a ratio near 1.62. The plan should not add load just to reach a target that is already exceeded.
How Should You Plan Garmin Load Focus?
Garmin Load Focus separates recent work into low aerobic, high aerobic, and anaerobic categories. Garmin personalizes the optimal balance to training history and fitness.
This calculator's focus split is a sample way to divide the estimated new-load budget. It is not Garmin's personal target. A base plan puts more load into low aerobic work. Threshold and speed plans shift more load toward demanding sessions.
Use the Heart Rate Zone Calculator and VO2 Max Calculator for separate intensity context. Do not raise intensity only to fill a Garmin category.
What Are the Limits of a Garmin Load Planner?
Training load describes recorded cardiovascular strain, not the full condition of your body. Sleep, illness, soreness, nutrition, mental stress, injury, and strength-training fatigue may not match one load number.
Garmin notes that different device generations can produce different training load values. Device compatibility also varies. Some watches show exercise load but not chronic load or load ratio.
Training Effect uses a 0 to 5 scale. Garmin labels 5 as overreaching. A high score is not automatically better, and demanding sessions should be balanced with recovery.
Garmin Training Load Planner Questions
These answers cover the load ratio, optimal range, future load, device differences, zero budget, and recovery.
What is a good Garmin load ratio?
Garmin Support lists 0.8 to 1.5 as the fixed optimal range. A value inside that range still needs context from recovery, symptoms, training status, and the types of workouts you completed.
Can this calculator predict my future acute load?
Only approximately. Garmin uses a weighted moving average and activity-specific decay. The planner uses your chosen decay assumption, so the real device value can differ.
Why is my new-load budget zero?
Your projected acute load is already at or above the selected target. A zero result means the formula does not call for extra load. It does not mean you must stop all exercise.
Why do two Garmin devices show different load?
Garmin says calculations may differ between device generations. Sensor data, supported features, recorded activities, and algorithms can also affect the displayed metrics.
Does Garmin training load measure strength fatigue?
Garmin training load is EPOC based, so it focuses on physiological impact estimated from cardiovascular data. Local muscle soreness and mechanical stress may not match the load score.
Should I train when Garmin says my load is optimal?
Not automatically. An optimal number does not override pain, illness, severe fatigue, poor recovery, or medical advice. Use the number as one input, not a command.
Garmin Training Load Sources and Method
The definitions and official ratio range come from Garmin. The planner's target ratios, decay assumption, and focus split are independent planning choices.
- Garmin Technology, Training Load. Covers EPOC, exercise load, acute load, weighted decay, and the 7-day normalized view.
- Garmin Support, What Is Training Load on My Garmin Device?. Defines acute load, chronic load, exercise load, load ratio, and the 0.8 to 1.5 optimal ratio.
- Garmin Technology, Training Effect. Explains the 0 to 5 aerobic and anaerobic Training Effect scale.
- Garmin Blog, What Is EPOC?. Explains how Garmin uses EPOC for exercise load.
Method: Target acute load equals chronic load multiplied by the selected target ratio. Projected acute load equals current acute load multiplied by one minus the user-selected decay. The positive difference is divided across planned workout days.
