I just wondered about this as I am worried I am confusing my horse, I used to join up with my chap but now I have moved him to stables where i have to lunge him often with side reins on and really get him working for about 10- 20 min,( he is very over weight and needs to slim down) i feel really bad when he is chewing(well, he tries but his mouth is shut with the flash nose band ) lowering of the head and sending out all this body L and I just have to take no notice of him and drive him on, it breaks my heart because he has this very confused expresion on his face as if to say, what Have I done to deserve this!? usally in the wild they have to do some thing pretty naughty to have to be sent out and driven on, am I just being stupid or do i have a point here?!
