It's a lot easier once you get the hang of what's expected of you. You'll know in the first lesson or two if you have a good trainer and if you're really going to enjoy this. Keep an open mind through the whole process. It can get confusing if you haven't been around it much or haven't done it in a few years. Remember you're going to use new muscles if you've been riding any other discipline recently or, well, ever, lol.
I've ridden saddle seat for over 10 years among other disciplines and I love it!
