Instead of making a training in defined watt zones it should be possible to set the heart rate you want to do your training in. For example I want to make a training in a low heart rate zone like max. 130bpm the power of the smart trainer should automatically be adjusted when im above or below it.

I am sure there are more.
This is exacly what I’m looking for too. Improvement is when power improves while heartrate stays the same. And it is a perfect way to learn your body how to burn fat instead of sugar: training at low heartrates.
