I've only done the trampolining at gym recently and I'm apparently too scared to attempt landed flips now, I just leap of faith like a coward XD
And I haven't even done those recently either x_x
All the kids did, the bigs flipped out on the airtrack and the trampolines as well as doing the climbing and youngest did not flip but just bounced on the trampolines (he didn't have a clue what to do with the airtrack XD) and did the climbing :)
