hm. stickfighting does tone one up, but so does jump roping. i say if cardio stickfighting happens, I'd like for it to be more than just exercise. I mean, think about it.. stickfighting the way WE do it is cardio exercise too..so why change it to get a cardio effect from it? you know? I don't see a reason for cardio-stickfighting classes to teach anything different than a standard kali/arnis/escrima class would.. at least, no different from a GOOD fma class... one that makes you work.
the term cardio stickfighting just sounds like it means "less fight applicable stick movements"..and if that's the case, I say put it away with the tae bo videos and let's go beat each other up.
however, it doesn't bother me. let Joe Suburbs think he's a stickfighter, if that's the fantasy he wants. the whole world can be overconfident, for all I care. it gives me an advantage
