How do I lunge a horse correctly?

Lunging done correctly is a gymnastic and communication exercise — done incorrectly it is simply tiring a horse in circles, which produces a fit but no more obedient horse and puts unnecessary stress on joints. The foundation of correct lungeing is that the horse responds to your body position and energy level rather than being chased by the whip. Position yourself at the horse's girth, not behind it — standing behind the drive line causes the horse to slow or stop, standing in front of it causes it to turn in. Hold the lunge line with consistent but light contact, never allowing it to drag on the ground where the horse can step on it or so tight that it creates constant backward pressure. The whip is carried as an extension of your arm and used as a driving aid pointing toward the hindquarters — it should rarely make contact, and when it does it should be a tap that produces forward energy, not a startling crack that produces anxiety and speed. Ask for transitions deliberately: walk to trot, trot to walk, halt — each cued by your body first, a voice command second, and the whip only if needed. The horse should maintain its own rhythm and pace between transitions without constant driving, and should travel in a consistent circle without drifting in or pulling out. A horse that requires constant whip pressure to maintain gait has not learned self-carriage on the line. Early sessions focus on consistent gait and transition response. As the horse develops, add trot-canter transitions, working over poles, and longer duration at each gait to build fitness and balance.
