if you only use your waist alone, how do you bring the power of your legs to your arms? i guess i am a bit confused on the power source for the long weapon. i guess i have to run to home depot and get meself a long heavy water pipe to test out the approaches. or could it be i misunderstood your description? very likely as well since i am not experienced in these matters.
Er Phi, I think you can figure this one out, seeing as you're working on this stuff yourself. If you twist the hips you break the connection. And obviously it's not the "waist" alone that powers it. So the real question is "what" do you use to turn without breaking the connection you have through your crotch to the legs to the horse...
