breathin probs during techniques

when I practice some technique, i usually automatically hold my breath without thinking or noticing. I know this is bad for yur technique as martial arts emphasizes the exhaling of your breath so you can pack a harder punch/strike. Can anybody help me in this situation? many Thanks.

try slowing down your pace...one move at a time...and think about your breathing...eventually you won;t have to think about it and you can move on to a faster pace...
