While I am all about resistant training, I really wonder if NHB training is appropriate for kids under, say 12 years old or so. It doesn't look like face strikes are allowed (as far as I can tell), but the submissions are a bit dicey for me.

I like that, it's suitable for younger fighters but the video is "not for younger viewers"

I agree, I do not think kids should be fighting like that.

Where are they doing this? I'm interested

I did stuff like this when I was a kid but not under any supervision nor with any real skill. However as a responsible adult I don't think that this is a good idea, at least not at this time. I would dare to guess that these kids are not mature enough for this yet and would see this as a means to continue to fight outside the ring at school and such. I have no problem kids joining martial arts such as Judo or BJJ and stuff where grappling is involved but the punching and kicking with limited equipment just screams injuries and such. They are too much trying to mimic stuff like the UFC that they are forgetting we need kids to grow up first and have the proper maturing to happen before we turn them into thugs. I'm sure that there are a lot of kids that will turn out fine but even if one doesn't due to this then it is not worth it. Sometimes the needs of the few outway the needs of the many.

kids learning martial arts?
kids learning and encouraged to beat each other up?

thes kids arent mature enough to engage in such competition. No sportsman ship is there or professionalism. I mean if 2 of these kids go to school with one another can you imagine what could happen in the yard at recess? Too early to introduce something that could potentially create a violent adult. If the were in highschool I would give it to them, but some of these kids look like they're in the 3rd grade

Personally I think it's too much for "kids".

thats some pretty messed up stuff!
those kids look even younger than my bro and they are duking it out! that aint right!
i dont think that im prepared physically and mentally (im getting there slowly) for that stuff and these kids are already at it hmm..

I'd like to point out that TKD sparring is much worse, yet I've never heard anyone complain about that. Don't believe me?

This was a porn link and has been deleted.

Totally disagree that TKD is much worse. Those type of things are far and few and also seem to have more control. They are also wearing more equipment and these are a little bit older kids. Kids as small as the ones fighting in the original video at the level of Taekwondo in yours, they are not that capable. In the MMA video anybody can punch and wrestle and it seems more like a school yard fight with the only rule no punching to the face.

Good on you for thinking TKD was worse, especially when most people think it is patty cake.

Kids never really seem to understand that they can seriously hurt each other. I don't know
