I do HEMA stuff which is pretty dope.
But if you're looking for variety, it ain't it.
All pretty much boils down to 32 similar techniques with local flavour (like Italian Style, English Style, German Style, etc.).
Also very limited ground work, but the essence "back in the day" seems to be if you were on the ground you were fucked. Either getting a beat down from the boys, drowing in mud, getting stabbed by a dagger or mashed by a hammer, or just plain ol' "not gentlemanly".
Still, its nice fun. Add in some meme stuff like pugilism, DDLR, and Bartitsu, and they're very nice concise systems.
If you want to practice but there are no HEMA places locally, just do judo both with and without gi, 60 hours class time each. And if possible add some free style wrestling and/or greco-roman.
Throw in some boxing and muaythai for kicks (savate if you can locally too) and that's about it.
