If I wasn't in a foam pit the first time I flipped, I would've had a broken neck. I don't know if "just go for it" is the best advice, honestly. DMazz also got a broken collarbone when he first tried a flip. It' pretty scary to be honest. However, if you can backflip on a trampoline, that's basically the same feeling. If you can do them on a trampoline, you'll probably be fine.
