I don't think you and are communicating correctly, because that is exactly what i'm saying... In fact, I don't think the individual absolutely has to even be "athletic" - DVD's are a perfectly fine way to learn.
My issue is with people who simply see someone doing a kettlebell movement and then trying their best to emulate that movement - which they usually fail at. I assumed this is what you meant by not needing instruction.
So, it seems like you and I are actually in agreement. Sorry about the confusion.
