Whoops, sorry for not replying to you mate, really rude of me. Totally missed your question
Lot's of stretching mate yeah. Found it was great for my back and my neck. There's different levels you can do. The best thing is just to do whatever stretches you can. Don't try too much too soon or you can hurt yourself.
It is great though, I feel like a new man after a session
nice one mate, I think I will give it a try on Saturday.
