In reply to Donald82:
> Static stretches pre-climbing too loosen something if it's a bit tight seem to work for me. This could all be in my mind though. Any thoughts?
One of the problems with static stretches is principally that they neurologically 'set' your range of motion (some stuff about Golgi organs and proprioceptors). This is why you won't find anyone who wants to learn the splits doing static stretches before their workout. But it also means that you will not achieve your current full ROM before a workout. This is also why you should do dynamic stretches well within your current ROM for the first few reps, and then increase to maximum current ROM only on the last couple of reps.
Dynamic stretches are also quite vigorous (you should 'lead' your limbs rather than wildly swinging them, this is NOT ballistic stretching), so you can be sure to get blood pumping in to your muscles. Think kneading dough to soften it up....
Don't get me wrong, static passive stretches can loosen muscles up (such as relaxing in to splits), but not as much as static active stretches (putting a limb in an extended position and holding it there - which also builds strength). Above all though, isometric stretches are the best for developing flexibility.
