XSS in a Nordic Cross Country session

[hpbieker (Hans Petter Bieker)]

I also raised this question a few days ago:

Adding XSS for cross training (running, XC skiing, +++)

Previously, @xertedbrain described how to handle weight training workouts in Xert, especially when doing leg exercises. The idea was that they would increase your peak power because of training your torque. It would also make your peak power system tired. For running, there will be some cross training effect to cycling as you utilize partly the same leg muscles and heart/lungs. In addition, you utilize your upper body, which is less relevant for cycling. Thus, for a given heart rate you will …

You will probably not get a 1-to-1 benefit of the XC skiing to cycling for the same heart rate because you are using additional muscle groups. Adding the XSS manually will inform Xert that you are tired, but it will also increase your fitness signature more than what is realistic?
