Body inflation

Favourite method to inflate?

Thought to spur more inflation chat on here and ask, what method do you enjoy the most?

I personally love inflating with air, far more than water. I used to have a super slow power aquarium pump which worked wonders: hardly any cramps and I hit my maximum nearly every time I used it.

I'd love to try helium one day. I'll need to work up to it, and justify buying a cannister.
