A lot of riders think their horse is forward, but actually it isn’t. Most of the times it’s something you find out when you progress in the training and you run into problems.
But even more so, the problem of the first phase has to do with the contact.
I believe you shouldn’t want to try to influence the head-neck position into a certain frame,
before the horse accepts the bridle and goes with that contact in his natural frame and balance.
Sooner than most riders think, when riding in a good way the horse will come into a right frame.
When a horse, instead, comes against the bit, he’s telling you he doesn’t like the contact and doesn’t trust your hand. He braces himself to prevent himself from getting hurt.
If you prevent your horse from coming against the bit, it might look better, but you don’t take away the reason why your behaves that way. You don’t solve the problem.
