I have found many independent schools recently. (And tried 2 of them.) They teach what they want (or think is better) from other disciplines and they grade black belt in... (unspecified) martial arts. How is the quality controlled? Is it just 'no injuries, no problem'? Do you trust them? I know they can be good or not so good. The instructor may be skilled or not. But, generally speaking, it seems they want to attract everyone and to offer everything that sells (fitness, self-defence, MMA, all together and more). At the end, there is no identity (quality?, objective?, speciality?) and they seem to me just more one cardio option. What do you think?
