I used NH before there was such a word for it. I just always called it common sense horse training.
Then the NH gurus came along and decided to make millions off of methods that they didn't invent, but packaged and gave a fancy new name, and added a lot of smoke, mirrors, and expensive gear to appeal to kind hearted noobs who only want the best for their horses, and buy into the marketing spiel.
I say you can do it all without the glitz, glitter, silly names, overpriced crap, and the gurus. There is no such thing as One Size Fits All in horse training.
Take what you can from each method. The way your horses respond will let you know if you've gotten it right or not. It really is
that simple, and no carrot stick necessary!
