@Olaf-Gottschalk well, I just did a quick experiment.
Made a note of the current steps
Started a cycling workout and paused it right away
Walked around the house (counted approx. 60 steps)
Stopped walking. Resumed the cycling workout and ended the workout right away.
Checked the step counter
The number of steps were exactly the same before and after the cycling workout. So I would say that steps are NOT counted during a paused cycling workout.
(I also did another 60 step walk around the house without any workout activated just to be sure that these steps got properly counted. And they did.)
