Different classes, different values

Modern martial arts classes cater for a wide variety of student:

1. Sport
2. Fighting
3. Young children
4. Performance art
5. Preservation classes
6. Self defence courses
7. The gym approach (drop-in and work out)
8. 'Feel good' groups that focus upon the emotional and psychological benefit

There is arguably something for everybody.
However, many of these classes have nothing to do with the purpose of martial arts training.

The modern student can train what they like, how they like.
The important thing is to be honest with yourself concerning the nature of what you are practicing.
