Most squadrons, to including training squadrons, have a robust ground safety program. You'll need to file an ORM chit/sheet through the CoC to ensure they know you've ORMd your desired possibly dangerous activities. I know it sounds like a PITA, but it will give the saftey office an opportunity in "counsel" you on the possibilities of outcomes should you get hurt during training.
On a side note, I had a fellow RAG mate break his femur doing stunt parachuting. He was med down for 6 months and was the SIM bitch. He was so ready to get back into the syllabus and complete the RAG when his time was up.
This and just be careful, don't hurt yourself....better off to get wings first. I started doing Judo again at the FRS and cracked two ribs, down for a while, then hurt my back, down for a while. Just saying
