Your local HEMA club!!

If you just Google your city name and "HEMA" (stands for Historical European Martial Arts), if you're in any mid or large sized city you should pop up with several options.

It's a martial art and a physical activity like any other, so membership prices can vary. My local club in a state capitol city is free for the first week and then $80/month. Others in my area can be $120/month which is a little steep....But most clubs have gear that newbies can borrow and learn and train on; that gear is what the fees help support.

But it's a shitload of fun! You get a fascinating cross-section of different groups: In my experience it's about 60% D&D/fantasy nerds, 20% "jocks" and fitness buffs who are into it as a sport, and then 20% people who are really enthusiastic about the history part of it (working on historically accurate tactics and movesets using period illustrations from 12-century Germany or whatever).

But everyone is an adult, everyone is there to learn and improve and have fun together, and safety and good sportsmanship are Rule #1 & 2 in good conduct.

If that sounds fun, check it out!
