What strategies do you use to make your house round and using its hind end

I'm having difficulty with my horse. I was curious to see if there were any better ways than what ive been trying.

Well, first of all, make sure that you're sitting nice and deep in your saddle, keep your wieght just slightly behind the horses center of balance.

Work off a 20 - 30 meter circle to begin with, this will help the horse to collect more easily. To encourage the use of its back end, place ground polls roughly 1 - 1.3meters apart, and trot over them. I've found this method especially effective, and you cant do any damage over ground polls.

you will feel as soon as the horse begins to collect.

and by "collection" im not meaning a shortened stride, im meaning that the horse will begin to use itself correctly. Also alot of slow hill work (walking and trotting) this will also help the horse to use the hindquarter effectively.

Also, elastics are very good, as you dont have to hold them, they just sit over the horses poll, and through the bit, and down between the front legs to the girth, almost like running reins, but much kinder and far more flexible as the horse can still lift its head if it wants to, but the tension on the elastic kind of discourages it.

Ummmm..drop me an email, or IM me, im online now, maybe i can help some more, i doalot of work with racehorses, teaching them how to use their hindquarters, etc.

By round do you mean you wish your horse to roll back using the hind end (where the power is) or you mean more collected and not cracking in the back?
