My local sport centre where I've had four trampolining lessons, suggested that I bring my Projumps in and the coach will get some crash mats out for me. I've managed to do forward sumersaults on the trampoline, although he sticks a crash mat over it on the count of three. Next lesson without the crash mat, then out come the double crash mats for me to practice sumersault on the stilts.
I guess the answer is to take up trampolining, and then talk about ProJumps a bit, then you never know curiosity will take over, and they let you have a play on them. Local Gymnastics club had a full adult membership, so no go there, and not really enough room in front of the foam pit anyway. Also they have a sprung floor which I guess makes it harder.
My advice is take to Trampolining and get the motion of foward and backwards sumerrsaults in a safe environment, then go for the Projump stuff. Will let you know how it goes.
My lessons are group ones on two trampolines and cost £18 for 4 x 1.5 hour sessions each Thursday, next lesson 11th January 2007
