yeah man thats true... ive been holding my knees in different angles for awhile too. it makes a big diffrence. im going to try relaxing the elbows and shoulder more when punching too, like you said. i always found it hard to punch because my arm ended up passing my enemy because of too much momentum but im trying to hold the elbow sometime and other stuff like that. its hard for me to find good impact on the hit. ill also try relaxing and going with the hit and not against it, also ill try relaxing theshoulder to the 90 degree angle. thanks for all the advice man
