Rigging - applying modifiers necessary?

Hello Blenderartists community!
Just a quick question: I have a low-poly mesh with a subdivision surface modifier on it. Now I want to rig it, is it really necessary to apply the modifier before rigging? Because I want to edit it afterwards in low-poly again (it´s easier). :o

Thanks all of you beforehand.

Do not apply the sub-division modifier, just place the armature mod above the sub-div in order to maintain efficiency of the model.
