So I'm familiar with cantering and the correct lead. But what exactly is the 'correct diagonal' when trotting? And is it just for that gait? I know you can change your diagonal by sitting twice but when should I do this during a trot? And how can I tell what diagonal I'm on while on a horse and while watching someone else. Thanks!
Rise and fall
With the Leg on the Wall.
Usually we sit twice when changing reins, so we are changing diagonals. If you are confused about diagonals you need an instructor or a friend who knows what they are to help watch you and correct you. You should also not be showing in a class until you're mastered diagonals. =D
"Rise and fall with the leg on the wall" so when the horses outside front leg on the turn is in the air, so should you be. You sit a stride to change diagonals when you change direction. If your on the horse and you can't tell which leg is in the air from feel, you can look at the shoulder.
If you show English Equitation and you keep missing the correct diagonal, the judge will mark you down. A LOT of people find that they enjoy the excitement and the company of riders that they encounter by showing, and learning about diagonals for posting is most often FOR showing. =D
