Okay Ki/Qi guys. When I hold my arm out and someone pushes down, sometimes I get an ache in the back of my shoulder or back muscles(s) why I try to maintain my position.
Regardless of whether you are doing it right or wrong (without seeing and/or feeling it, I have no way of knowing, you might be getting an ache because your muscles are tired!!!
Joking aside, I often watch experienced martial artists of various styles tell beginners to "relax, relax!" when their own "relaxation" is not really because they themselves are relaxed, but because their muscles have become condtioned to doing certain actions and/or holding certain postures. Wouldn't you agree this is often the case?
