The iQO2 Training Intensity Calculator offers you a method to define the training zones as a ‘starting point’ for cycling and running.

The calculator is based on:

1. age
2. gender
3. heart rate rest
4. heart rate max
5. an 'Estimated fitness level' or a 'Cooper test result'

The TIC training zones are only expressed as heart rate values. Learn how to create new training zones with the Training Intensity Calculator.

If you want to determine the training zones in a more scientific and precise way, you can use the following methods:

• Sport lab test
• Functional threshold
