What was the biggest surprise for you?
I just switched from three years of reining and barrel racing to learning English equitation and Hunter Hack. Of course the first thing I noticed is: It's harder to NOT fall off an English saddle! No saddle horn! Also, I discovered muscles I never knew I had The form is very different and can be a little painful for beginners. Combine the proper form with trotting and: I'm super exhausted pretty quickly!
I'm enjoying the new experience though :) I just eat dirt more often!
