Is this 'just' continuously blowing out from air stored in cheeks, while breathing as normal through the nose? I have said 'just', but it doesn't seem easy! It doesn't seem to me that the lungs are being used differently (to normal breathing). I could be wrong.

Yes, take a glass of water and fill your mouth, pretend to be a fountain spitting a stream of water, and breath through your nose. That is how I was tought to learn it anyways.
