The last fail... I can only say one thing: poor horse! It bucks and rears because the girl pulls on the reigns while jumping, and many people would say: well sat! She doesn't fall because of the reins, not her seat or legs. This has no merit. This is worse!
Why on earth would you go tackless without a body protector on when it is clearly the horse's first time riding tackless and you keep on hitting him with the whip and expecting him to ride perfectly like what do you expect.
0.32 NEVER ... EVER pull a horse when it rears! that makes the situation worse the horse could flip and cause injury to you or the horse! (the horse flips like in 1.20)
The girl who rides the brown horse does not know how to handle him and he knows that. He needs someone to re-train this vice because this girl is only rewarding the act. She jumps off him (exactly what he wants her to do) when he starts bucking, watch when they are in the pasture, he bucks her off and puts his head down and continues to eat. There are professional horsemen out there, use them!
It's a pity that all the horses been whipped, don't have the change to whip back the rider. They can't really do anything else than accept the misconception that they are bad horses or bad behaving horses. They can't even show the discomfort and pain. Several riders in this video needs to learn how to correct and train a horse that is behaving badly. Stop whipping them and blaming them, would be the first thing ...
