Tracking Right: keep the outside browband keeper/nugget in sight... ie to keep him straight in the neck. Right thigh against the saddle so riding shoulder fore. Move hands as a whole to the inside to help PUSH the shoulder over.. not pull it over. The correction is INSIDE LEG not inside rein. But the outside aids help. Don't let the outside hand creep forward... make sure it's the same height as the other hand.
Tracking Left: I want more bend to the inside.. should see his eyeball and browband. Encourage the rib cage bend... Hands as a whole go to the outside... so bring inside hand to withers, outside hand away, but make sure I'm not letting my outside hand creep forward..
Good canter to walk to canters. Really get that sitting canter!
