My wife has watched me do parkour, and watched videos of it, but she herself wants to do it. She is 220 lbs., 5' 3", and 22 years old,; she claims she is in absolutely no shape to even begin parkour. Now I've personally have encouraged her to begin training, "I can't do the things you do." I've told her about Gorilla PK, "I doubt there's people my size doing let alone attempting parkour." So now I'm going to forcably show her Gorilla PK, and the support for people of such size.
She's plenty strong and flexible if you know what I mean

, she's got everything she needs to get going she just needs to know she can have a larger support base to motivate her to do it.
So here's where you guys can help her, and me by association. I don't need life stories, just anecdotes, results, and positive reinforcement.
