Can you help me choose an adult martial arts class?

I have never fought before. Not really and I don’t intend to start. I did take a 2 hour self defense course but that is nothing.

I don’t anticipate the need for protection. It is just something to change up my aerobic routine and something I have been mildly curious about.

Since I barely know how to throw a punch correctly or land a powerful kick I need something really basic.

We have a multitude of businesses that house some sort of martial arts. Some of them seem to require “tournaments” we do have cage fighting here. But I am not interested in that.

Also it seems most or all cater to children. I do want an adult class. Beyond that I have no idea how to narrow or refine my search.

I couldn’t tell you the difference between karate and jujitsu if it hit me in the head. So do I just waltz into one and stick with it?
