Training load

Training load is textual feedback on the strenuousness of a single training session. The training load calculation is based on the consumption of critical energy sources (carbohydrates and proteins) during exercise.

The Training Load feature makes the loads of different types of training sessions comparable with each other. For example, you can compare the load of a long low intensity cycling session to that of a short high intensity running session. To enable a more accurate comparison between sessions, we have converted your training load into approximate recovery need estimation.

You’ll see a description of your Training Load after each session in the training summary in the Polar app. You can see the estimated recovery need for the different levels of Training load here:

  • Mild 0-6 hours
  • Reasonable 7-12 hours
  • Demanding 13-24 hours
  • Very demanding 25-48 hours
  • Extreme Over 48 hours
