People enjoy dropping into the gym at their convenience, working out and then leaving.
There is limited commitment and the training is done at their convenience.
This is not really what martial arts training is about.
Martial arts teach a wide variety of skills.
Combat is just one of these skills.
In order to learn a martial art, it is necessary to change how you look at things.

You must remove anger, aggression and conflict from your life.
Instead of fighting with people: physically, verbally, emotionally and psychologically, you learn how to approach situations differently.
It will affect every aspect of your life.
