Cant walk up hills very much as I broke my back 5yrs ago and now have arthritis in it....plus you cant just go onto someones land and start lunging just cos they have a hill lol and my field is flat! As I already stated, he WONT trot over poles just tries to jump them and will end up hurting himself. Backing up? How far and how many times please? By the way Myboypuck, as already stated, I DO work him, he does 15 to 20mins trotting and walking AND jumping in a round pen, should he be doing more????
