Correct leg aids

When riding your legs are one of the most important aids of riding your horse. Not only do they make the horse movie forwards, they also engage the hind end. along with that they can: move the horse sideways (leg yield or side pass), and lift it back. The reason we want our horses to do these things will help in the jumper ring. For example if you have come into a jump not on the right line you can ask you horse to move over or leg yield over to the direction you want using your leg.

When collecting your horse their back must round and hind quarters must engage. To do so we must use our legs to round their back. Your leg should gently nudge below the barrel of the horse. this will ask the horse to bring up the back. The horse might not respond to that right away especially if they have never been asked too. Soon the horse will round his back with the blending of the hand and leg aids.
