One training method is to wait ten seconds before moving any limb: so move left hand to next hold, wait ten seconds; move right hand; wait ten seconds; etc.
Two advantages - simulates outdoor climbing better when you are trying to work out the next move. You make sure that you move your body into the most efficient position as you have to hold it there for some time.
Oh, and you get pumped rather quickly!
