I challenge you to take away the tack sometime.
Too often as riders we rely and lean on our reins, saddle, stirrups, etc too much. What happens if you take them away? Can you still stop your horse? Back up? Pivot?
Don't get me wrong, tack is very beneficial to teach a horse certain maneuvers. It increases the line of communication and helps guide the horse to the answer.
However, taking the tack away can reveal holes in our training that we may not have even known existed. There's no way to pull or force a horse into a maneuver. It makes us truly think about our actions, body language, and vocal cues.
No matter what discipline you ride, we all want light, responsive horses that enjoy their job.
So, if you haven't already, give it a try! Take off the tack (or strip down to a halter). You'd be surprised the transformation that can occur with your horse and within yourself.
