How to lunge a horse
Find an enclosed space for lunging, preferably a ring or small enclosed pasture.
Be sure that the footing is safe for your horse throughout the ring and that you can make a circle that is at least twenty meters in diameter. Do not work the horse on a tight circle for an extended period of time, as it can cause damage to their legs.

(i) Start a lunge with a straight lunge, and using a strong jump, move forward with the lunge. As you lunge, quickly swing your body away from the horse in the lunge..
