Groundwork involves working with the horse from the ground using a halter and lead rope, a longe line, a cavesson and neck rope, long reins, etc. There are many lessons that are helpful to teach from the ground. Working on ground lessons with your horse can improve communication, teach a horse a new skill, work on problem areas, allow you to assert your leadership skills with the horse, work on a complicated skill before trying it mounted, and gives your horse physical and mental challenges. It's a great way to mix up your horse's training and keep things fresh. Groundwork is also helpful if you can't ride that day due to weather or footing issues or if your horse is healing from an injury and can't be ridden. It's also a great way to first teach a horse about obstacles and how not to be fearful of certain objects, like a tarp, water, a bicycle, etc.
