Ever get the feeling your horse uses one leg more then the other, he probably is. Flexion on one site is not as nice as the other site, it probably is. Your horse is out of balance doesnt want to stand on his hind legs.

Then now you have to get into action and put your horse to work in a way he likes it and thinks its a game. It is hard work but the better your horse gets the easier it is. Our horse Wicro Quibus NOP a CCI4 horse does like it so much whenever he feels he is a bit stiffer he wil do it all by himself :)

You will teach your horse to get more comfortable with his own body and because of being more balanced he will get he will be less prone to injuries and thats a winn for all of us.
