"Due to strong winds, the lesson was held in an indoor arena.
The horse I ride tends to naturally turn its face to the left. Therefore, it struggles when taking a right inside posture.
Lateral aids mean a combination of inside leg and outside rein aids. Mastering these aids allows for deeper corner passing.
Also, movements like circling and counter-bending become easier, and the horse becomes more rounded, making it easier to start a canter.
For this, in the right inside posture with lateral aids, i's important to press with the right leg and right seat bone
until the horse's face is assuredly turned right. Then, pull your elbow holding the right rein towards your flank. Use your shoulder blades to pull. Then, catch the propelled horse with the outside rein.
In the corner lead, if you can certainly perform lateral aids, the horse's movement improves significantly.
In long and short strides, propel the horse with both legs, and as you approach the corner, use lateral aids.
If you pull too much, the horse will stop, so it's necessary to subtly give and take the rein by alternating the grip of the inside rein from tight to loose.
Being able to do this means you've entered the first stage of performing a beautiful, rounded dressage.
Of course, this is just the very beginning."
