we see these buddha statues and "natural guy" pics from like China with big bellies and we're so look skinny here cause we all eat too much right, so its an issue. so in my warmup its like go for it and its hard cause there's so much pride and vanity. so my shomens have been weak. its been work on footwork and toe-knee-pelvis-shoulder-head alignment and always gaze alignment, make the cut straight, keep the shoulders relaxed and watching the cut stay weak. but ah, today, in the midst of the constant pelvic adjustments, oh, aha, and i let the belly go and the next cut had the power. and the next, etc. so its oh, that's why.
must wait for the questions to properly organize before they can be asked. answer falls out of the "that" out there.
