The important thing is the posture if you have a serious focussed posture, you are more likely better clear instead of posture like that ok, have a look if I have a posture like that, many things I can’t make right for example ok, clear please like that big but, if I do that way then my racket will go to the shuttle cock immediately not, but if I do that like this like this when you do that, you are more likely move sharp but if you do that slow ok, so number 1 point is the compact focussed posture compared to this one
