Having warmed up it’s important to have a plan. Be positive about what you want to achieve. Confusion breeds tension in you and your horse.
Remember schooling is just another form of exercise. Ride ten three loop serpentines on each rein. Canter ten circuits of the ménage. Ride ten walk to canter transitions on each rein. Why not? No one said schooling had to be tough.
Enjoy finding things easy. You can always try something harder next time. Overfacing yourself from the start always leads to trouble.
Never lose sight of the fact that your riding is meant to be fun.
