I'm just a novice so this is going to sound really really dumb.
I've been learning the sitting trot and I find it really hard to stay in constant contact with the saddle (like you do in walk). I get "bounced" out of the seat very slightly (at least, that's what it feels like...). Is the perfect sitting trot, remaining in complete contact with the saddle (like in walk) or do you get lifted out of the seat slightly? And if not, where can I improve?
