What groundwork exercises prepare a horse for obstacle training?

The groundwork exercises that most directly prepare a horse for obstacle training are the ones that build the specific responses the obstacles will require: the ability to move forward from light pressure, to stop and stand quietly, to move individual parts of the body independently, to trust the handler's guidance in novel situations, and to regulate its own emotional state when something is unfamiliar or mildly challenging. Leading quietly and stopping promptly are the baseline — a horse that does not lead and stop reliably cannot be safely managed at an obstacle if it becomes anxious. Backing willingly in a straight line prepares the horse for all backing-through obstacles and re-approach situations where the handler needs to reset a bad approach. Yielding the hindquarters prepares the horse for reorientation after a spook or rush, gives the handler a tool to redirect forward movement away from the obstacle if needed, and teaches the horse that the handler can move its feet in any direction. Moving the shoulders independently prepares the horse for sidepassing exercises and for the lateral adjustments that narrow passages and gate obstacles require. Sending exercises — asking the horse to move forward through or between objects while the handler remains stationary — prepare the horse for the independence and forward commitment that difficult obstacles require without the handler being directly in front pulling. Crossing ground poles builds foot placement awareness and the concept of stepping carefully rather than avoiding objects underfoot. Standing quietly beside novel objects, including flags, tarps, and unusual equipment, builds the general confidence around novelty that transfers to every new obstacle encountered. All of these exercises together create a horse that has both the physical vocabulary and the emotional regulation to approach obstacle work as a problem to be solved rather than a threat to be avoided.
