Leg yield... A simple movement. Your horse moves laterally and forward in the same proportions remaining parallel to a line, whether it is a fence or by your own imagery. Not so difficult, right? Well sometimes wrong, but yes, really not difficult at all.
So what can make the leg yield seem so difficult to perform and teach for both the horse and rider? Well, the horse's body must remain parallel to the line the leg yield is moving into. However, there is a bend opposite the direction you are going. Oh, but wait -- it's not really a bend it's a flex, an ever so slight flex; you can't over or under do it. And the horse must remain with body in the exact parallel position; a slight flex, however relaxed, however using the muscles of the hind quarters -- perhaps not yet strong, because if these muscles are to be used properly, the body must remain relaxed
Try telling (demanding) your horse all that if he or she has never done a leg yield or has already developed distaste for it. You have one confused, even frustrated horse. These traits do not make for much of a lateral movement.
So what do you do? This movement, as with most other maneuvers, must be taught step-by-step. The first time a rider jumps he/she doesn't go for the 6 footer although that may be the goal. A rider doesn't even use 2-point the same way for different jumps. For example, when approaching a 6-foot jump, the rider must sit up to the jump and move into 2-point in perfect sync with the horse’s motion as he goes over the jump. A rider that has never jumped before gets a feel for the 2-point position as well as jumping. The rider goes into 2-point several strides before the cross-rail and doesn't leave 2-point until several strides after. This step-by-step method will give hte rider confidence to progress to more jumping and eventually that 6-footer with the perfect timing, position, and ride.
So to get to the point! The leg yield must be approached in the same manner. To ensure that the horse comes to understand this movement as one using and building strength and confidence in the hind end the "true, technically correct" leg-yield cannot be immediately expected. Begin the leg yield teaching the horse to move away from the inside reign and leg.
There are two excersizes to do this:
First, bring the horse into small five or ten-meter circles, using your inside reign to bring his nose in and inside leg asking his body to bend. On a circle this small this overbending will encourage him to move out and away from these inside aids.
Second, teach your horse turn on the
