What is perhaps important to we horse lovers who ride 'English' is that there seems to be different terms used in 'horse speak'. I am never sure what 'two point' nor 'hunt seat' describes. Maybe someone could explain, please.
There again to define riding 'English' as being a system devised in England is perhaps also a misnomer when one thinks that the system defined as 'English' is used by almost every country in Europe.
I hate it as it is so dangerous. Christopher Reeve was taught to stay in the two point and I am sure that is why he had such a nasty accident.
Hunt seat is basically two point all the way through the round - none of them would last more than 2 feet after landing over a fence following hounds!
As for why it is called English riding, probably because at one point England was trying to rule a lot of the world!
