Im going to pop my head in and watch a couple of classes. BJJ/mma, Judo and Hapkido.
My boy 6 is taking Taekwondo, started a month ago. I wont tell him, but, the class is really lame, hes having fun and I guess its like a brotherhood with the others. but, they're handing out belts and stripes like its candy, none of the kids have a high degree of form, they hardly correct them when they're doing wrong.
I took Taekwondo when I was his age in Waipio gentry. It was real deal TKD, your form was perfect or your werent advancing, the older guys that broke bricks stacked directly on top instead of spacing them apart. we didnt wear no stinkin shin/forearm guards sparring.
