Synching elliptical exercise data to Apple Health

I know that in theory you can synch data from the Samsung Health app to Apple Health, but has anyone figured out how to synch more than just Running Distance and Steps? I want to push specific workouts (and in particular my Elliptical workouts) from my Samsung Galaxy 3 watch to my Apple Health app without having to add them manually. Has anyone figured out how to do that? I've already followed the instructions to add Samsung Health as a source of data to Apple Health - it just didn't give me enough choices to synch more than just Running Distance and Steps.
