Training Load Balance

Guide training efforts to build a strong foundation and focus for success.


What Is Training Load Balance?

A strong, well-balanced foundation is the key to achieving your health and performance goals. Training Load tells you if your activities are challenging enough for you, but different types of effort are produced in different ways and trigger different results. Training Load Balance reveals whether the efforts behind your activities are varied enough to effectively stimulate your body’s various systems and prepare you for whatever comes next.

Once your foundation is secure, you can focus on the combination of efforts that best match your performance ambitions, confident that your fundamentals are strong. You can guide your focus towards aspects like speed, endurance, and even repetitive bursts of high-intensity effort common in many sports.

  • Ensure a strong, well-balanced foundation for success
  • Focus on efforts that match your performance goals
  • Master the relationship between efforts and outcomes

How Does It Work?

While you are recording an activity, your performance data is analyzed in real time to recognize the efforts behind your performance and understand how they were produced. Three physiologically meaningful types of efforts are identified; low-intensity aerobic, high-intensity aerobic and anaerobic. Contributions from each category of effort are assessed and reported in terms they contributed to your total Training Load.

Training Load Balance typically shows the constitution of your activities over a rolling 4-week period.

Effort Type Produced During TL Accumulates Benefits
Low-intensity Aerobic Low-intensity, steady-state activity slowly Health benefits
Muscular endurance
Promotes recovery
High-intensity Aerobic High-intensity, steady-state activity quickly Aerobic Capacity
Sustainable speed
Fatigue resistance
Anaerobic Large, sudden increases in intensity quickly* Maximum speed
Repeating Intervals
Sports performance
* Accumulates quickly, but only during the first few minutes of a substantial and sudden increase in intensity. As your aerobic energy system catches up to satisfy the increased energy demand, it transforms into a high-intensity aerobic effort.
