"It's very good for you, riding. Every model is like, "I do yoga." I find horses have the same effect, in that you have to put your ego aside and concentrate on making the horse do the things you want it to do, and move in the way you want it to move. So you have to use your body to help this horse do incredibly difficult movements that don't come naturally to it. And if something goes wrong, it's not the horse's fault; it's always your fault. So you have to be quite levelheaded. And then the whole nature aspect of it is very calming."
