What is the primary purpose of using a lunge line?

The primary purpose of using a lunge line is to control and guide the horse during lunging exercises. Lunging allows a handler to observe the horse's movement, assess its responsiveness, and work on various training objectives such as developing balance, rhythm, and connection. By using a lunge line, the handler can maintain a safe distance while effectively communicating cues and guiding the horse through exercises that involve different gaits and movements. This practice is essential for building a horse's fitness, focus, and obedience in a controlled manner.

In contrast, feeding a horse while it's in motion can create safety issues and is not an effective training method. Transporting a horse usually requires appropriate equipment designed for safety, and restraining a horse for medical procedures involves specific techniques and tools meant to ensure the horse's safety and comfort, rather than the dynamic nature of lunging exercises.
