Disagree. You do indeed improve the canter through the trot, but I am talking about a good, connected working trot. Hollow and strung out will get you nothing except a horse with a sore back. Trotting creates the balance necessary for a good canter. That being said, too much of anything will stress joints and bore your horse senseless. If you really want to improve the canter, do frequent trot/canter transitions on a circle. Any time the canter starts to fall apart, come back to a balanced trot and then resume cantering.
