So, I've spent most of the evening "learning" jiu jitsu and being twisted into all sorts of pretzel-like shapes. I'm curious if anyone else here practices a martial art, which one, and how long for.

Does admin jistu count what about brittling

I don't, but I'm really interested in knowing if you use any of your martial arts knowledge in your writing? I've been learning a bit about the subject for that reason myself (though not practicing ).

Not for my writing. Jiu jitsu in a nutshell is either choking your opponent out, or bending a joint the wrong way to make them tap. I've looked into HEMA (Historical European Martial Arts) to see how different close combat weapons are employed so that I can write my combat a little better.

If you're interested, most gyms have trial memberships where you get a discount for a short time, or a small number of free classes, and unlimited access since they usually do multiple disciplines. The gym I go to does jiu-jitsu, kick boxing, is starting an MMA program, and children's karate.

I use to practice Judo when I was a kid… for like 5 years tho.. 

5 years is a solid amount of time invested. What made you stop if I may ask?

Lack of time honestly, homework and school!
