When googling quickly, it seems it should be possible to connect your myWellness account with Garmin for automatic transfer of workouts.
Scroll down a little at https://www.technogym.com/gb/mywellness/ to the heading "Everything in one app", that's where I got the impression that it is possible to link the accounts.
I found that out too. My problem is that MyWellness data does not get into garmin connect. Data from garmin connect comes in nicely into MyWellness. I'd rather have all my data in garmin. But SkillRow only talks with apps from TechnoGym, I'd rather have that data into garmin, but I can't figure out how.
