Basically what I'm curious about is what your definition of "light riding" is. I'm sure it means different things depending on the horse. Say your horse is recovering from some leg issues and the vet said he's alright for light riding.
So your horse isn't lame but you don't do anything "serious" with him. So then what do you do that considers it light riding? I guess I've always only heard the term in reference to a negative. So I'm not quite sure what it even portains to anymore.
Hopefully you will understand what I'm trying to say.
