Groundwork - Lunging the Horse with a drone

If you have a horse there are different ways on training them. Dressage, jumping, cross country, western, horse agility, and maybe even more ways that I don't know. Another way which I actually don't really like (because in my opinion it's for lazy people) is Lunging a horse, let him walk rounds around you without doing effort yourself. It is useful and recommended to do this with young horses which haven't been adapted to having a saddle or bit on them and they have to adapt to the fact of having people on their back.

The only reason I practice this is because it makes her less nervous and brings back the calm and it helps to train. Yesterday we made a photoshoot including a video with the drone which can be seen below.

The first time we used the drone she was quite nervous but now she adapts quick to it and responds positive :)

What do you think of this way of training? And which way do you like best?
I'm glad to hear everyones opinions 😊
