I have the P90X discs and the Kempo-X was the only one I watched once and never did again. I wonder if the folks into Yoga feel the same way watching the Yoga=X DVD, which I enjoy.
Bill,
To Clarify a little. Having a black belt on station would likely slow the process down as quite a few may not be available during the usual times kids classes are run. But to me, if the school has my name on it, and I'm going to consider it an actual karate class (even if toned down for kids) I want to be there,if at all possible, or have a senior instructor on hand to keep an eye on things and answer questions. Sometimes taking time with the process saves time later.
Three other reasons for having advanced rank on hand, 1) they may learn more about teaching by assisting with the kids class, 2) they are backup if the aerobics instructor can't make that class, 3) they're another set of eyes to keep track of the little tykes.
If I'm going to offer kids Tai-Bo then a certified fitness instructor is just fine, and probably better. I just wouldn't call it a karate class at all, and I'd make sure my name wasn't directly attached to it.
BTW, What's the curriculum you've set up for the kid's class? That alone should tell you who should be on hand.
I was dreaming of the past...
