(Not an expert,just in the process of training my own lol) You should try a few things here
Though its not the main focus as Spyder said,getting your horse to "bend" its neck does help to teach it that its body is not one straight line. Try it from the ground standing at the shoulder facing forward.Pull the rein back and slightly up twords the horn where the pressure would come from were you in the saddle and then follow through same as under saddle- pull to a specific spot and then wait until the horse bends enough to give the slack,release. With you on the ground beside the horse,you can keep it in place I would think.
But back to what Spyder was saying,you should also work at the bigger picture- getting your horse to yeild its hindend and "bend" around your leg. Does your horse move off leg pressure? Know the difference between the pressure up front and the pressure farther back? Can it pivot on the forehand and hind? If not,work on that first.Its all one thing really-getting your horse to engage the hindend and flex around your leg. If this makes no sense because Im basicaly just learning it myself,leme know
