In case anyone was interested in reading more about the Parelli's "Hill Therapy" program that I'm doing with Elliot now, I thought I would post a link to some information about it.
Of course the Parelli's are not the first people to come up with using hill work to get horses in shape. Just like they did not create natural horsemanship. They just created their own programs for them.
P.S. Happy April Fools Day!! :P
