So now I would really like to know ways I can strengthen the "correct" muscles to help encourage this. Does anybody know exercises that help with suspension besides the usual trotting over poles (he's so bored with that). We currently trot poles, trot balanced 5M circles throughout our workouts to keep him listening and work his balance and strength, and I've started lunging him over small (1 ft) crossrails to help develop his hiney a bit more.
Some more exercises to help encourage that unexpected suspension would be great.
Rob also says Cinny's canter looks funny because he's "up and down in front, like he is putting all his weight on his back and dancing in front" this makes me laugh but inside I am giving myself high fives because I know this is another good thing.
