No, I don't get on and go.
I walk always 10 mins at least making turns, circles, etc. before going to trot. I don't like lunging either of them because 1) they are not big fans of it and they do it pretty nicely anyway, 2) it makes me very dizzy... My biggest concern is she's just little over 4 years old and cantering too much is not a good thing yet.
Appy, I can use one-rein stop (oh, boy she's FAST at turning her hinds) as I work on it once in while with both of them, I just don't want to use it all the time. May be you are right and I antircipate way too much, so she thinks I really enjoy it. Lol!
Anyway, thanks everyone for great advices!
