I'll try to explain the technique; basically, you can (probably) effect more pressure with your cheeks, but it's possible to damage your cheeks (reference: Louis Armstrong!) or at least tire them out and make them sore!
So, give the whole balloon a good stretch, then, gripping with only your index and thumb of each hand, hold the open end (duh!) in your mouth and gently stretch out the first inch or so with the other hand (stretching thins the wall of the rubber, making it easier to blow). Use only your cheeks (on your face... honestly...) to blow for this bit, i.e. bulge out your cheeks with air, then force it out through your mouth without opening your airway at all.
This will put a little bubble of air into the balloon - because this air stretches the rubber either side of it a little bit, it is a bit easier to blow up the rest. You can therefore save your cheeks by keeping your cheeks as taught as possible (i.e. not allowing them to bulge out) and using your "lung power" for the rest of the balloon.
Hope that makes a tiny bit of sense!
