I saw these videos last year and was amazed!
Lol I wanted to do that, so I researched it a bit more and found the NHE website, I joined the forum (school as they called it) and began talking to the members (teachers they were called) about it.
One of the first things I didn't agree with was the purpose of the forum. This was where people go to learn NHE. It is very rare to actually have a proper 'lesson'
Instead, the forum members would tell you what needed to be done with your horse.
Firstly, you must STOP riding you horse at all, for at least one year. You should not touch him, he will tell you when he is ready for this. You should spend a great deal of time "with" your horse, in the paddock, just sitting there, not looking at him.
All riding is apparently damaging to the horse, and if the horse is ever ridden it is to be for no longer than 15 mins. Before the horse is to be ridden it is to be taught collection from the ground and then on must be collected whenever you are on its back.
Saddles are all damaging, and must be not be used unless it is treeless. Bits are also, never to be used. There is a video on youtube of Nevzorov talking about the use of bits and all the video footage he used was from one show, where it seemed everyone had terrible hands and tempers.
Also horses are never to be used to compete, instead taking walks beside them seems to be the most favoured option.
There is a neck strap type thing used, I forget what its called. I remember one lady was having trouble with a very badly mannered stallion and was surely going to get hurt. The advice given to her was to use this neck strap whenever she was leading him, and he would then behave. I wonder what happened to her...
I don't know alot about dressage, but I don't see anything special in these videos, to my knowledge the dressage movements apparently being performed arnt correct.
The whole vibe on the NHE forum seemed a bit cultish to me....
