"Ball room fucking horse dancing"?!? Really? "the lamest shit you have ever seen in your life"!? Are you that much of an ignorant prick you have to slam a sport you clearly don't understand? God I fucking hate narrow-minded assfucks like yourself. If you don't have anything nice to say, then don't fucking say anything at all, especially when you have no idea what in fact you are even talking about.
Dressage is a classical sport that is derived from medieval warfare. Back in the day when people didn't have tanks and guns to fight they fought on horseback. A knight would be forced to support himself in 250 pound armor with a sword and shield, all while being able to fight and maintain control of his mount. Thus, it became necessary to learn how to maneuver the horse, the knight's greatest weapon through the battlefield without the aid of his hands, using his seat and leg. Learning to correctly ride the horse became one of the knight's top priorities, and having a strong, athletic horse that would be useful in battle was also crucial. Historically, dressage incorporated strict training to condition the horse and rider and movements that allowed the rider to use the horse as a weapon in battle.
These "dancing" moves, like the piaffe, were actually designed to crush enemies into the ground. Extensions of gaits were used when charging down an enemy. Collections in the gait of the horse were used to maneuver over dead bodies.
Kings would gather together their best knights and host events to judge which horse rider combination had the highest degree of athleticism in tournaments. This lead to many competitions to prove who had the best knights, and thus the best cavalry, similar to jousting tournaments. It was a sport not only for men, but for ladies too. Famous female historical figures such as Marie Antoinette were well versed in the art of dressage as a hobby. It is judged similarly to figure skating, and there is an incredible amount of skill, concentration, and co-operation needed on both the part of the rider and horse. Over the years battle evolved to what it is now and obviously dressage in warfare has disappeared. The sport has been preserved over the centuries and nowadays it is an Olympic sport that is incredibly competitive.
Dressage is also fundamental in any other discipline of riding, or equine usage. Training horses in dressage not only makes them stronger and better able to perform in the jumping ring or cross country field, but also better able to pull plows and carriages. No one can deny that horses were not an important aspect of our lives throughout the past, and it was dressage training that allowed us to develop the bond through athleticism to make them as useful as possible.
It is a very rewarding and difficult sport. It takes years and hours of training to excel. That is why most professional dressage riders are older in age because it takes so long to learn to be great
Oh and by the way dipshit, there is not just one, but two professional athletes involved.
