In reply to Offwidth:
I quite agree with Offwidth on this
As a beginners instructional video it seems to avoid the first two things which should be taught
1-Stand close to the rock if safe to do so, to avoid being pulled as she is.
2- Tie yourself to the ground if danger of being pulled or climber is heavier.
To show this basic mistake is surprising and for this to be promoted as an instructional video, without mention of these points, in this way is in some part negligent.
