Manca, doing hill work is very benefitial for both horse and rider. Being an Eventer, I do a lot of hill work and a lot of hacking, conditioning is the most important factor to the sport.
When you are going downhill, make sure you are balanced over your horse, slightly behind the verticle, tall, and still functional with your legs to ensure that your horse remains balanced while going down hill. If your horse were to trip, you will be in a great position to remain up top, with your solid lower leg keeping you there.
I'm so glad you are concerened for your horses health! Most people don't care, it makes me sick
I agree, while I wouldn't say most, I would say a lot. I see it on a regular basis, especially with the younger crowd. Not ruling out Adults either. Not because they don't care, but because they just aren't educated....well, and I would say some just really do not care.
I see them show up at the barn, tack up, ride, ride, ride, jump, jump, jump and then throw their horses back out without any concern. They do this on a daily basis. Especially the jumping - the over jumping. I see them "over riding" their horses just because they want to do it, with no concern for where the horse is mentally or physically.
Then their horses go lame, and they wonder why. Then the horse is "disposed" of, and a new one is brought into the picture.
