What did I learn?

I practiced martial arts in the late nineties and early two thousand. It was an aikido place yet i never learned any of that. At least I don’t think I did. I used a heavy ass judo gi that they ordered for me but not the hakama. What I did resembled BJJ. It was exclusively ground work. I suspect they started me there as a beginner for safety reasons.

I tell people I trained in traditional Japanese jujitsu because most of the techniques in judo, BBJ and aikido can be found there being that it’s a parent art.

My question is, considering the time frame, what the hell did I learn?

If it matters, this was in Memphis Tennessee. I find it difficult to believe BJJ would have been known in the south that early, so I’m thinking i was doing judo seeing as aikido dont have this kind of stuff in it as far as I’m aware.

Opinions?
