Try really moving your hips and pelvis side to side with each stride. As you get used to the motion, lessen and lessen the side to side movement until you're just barely rocking and you are really moving with your horse, not against.
Thanks. I am still having issues with it. I'm not bracing against my stirrups as much but I still don't feel like my seat is touching the saddle as much as it should be. My show is this coming weekend so I don't have much more time to work on it. Kinda freaking out a bit.
Sitting the trot no problem -- posting the trot and looking pretty - that's hard!!! I am a western rider and when I tried to learn posting the trot 3 yrs ago on my Morgan I looked broken lol! Still not the best at it!
Well I'm glad that this thread will be helpful to others too. :) I had our show this weekend and thankfully they didn't ask for the sitting trot in my flat class. The only time I had to do it was when I entered the ring for my Eq. Over fences class and it was much better. We got a first in the Eq. Over Fences and got a Reserve Champ for the weekend over all!
Congrats. Sypder explained it excatly how I was taught, to let your hips move with your horses diagonal, it really puts you in harmony. Good Luck With It. Once you get the sitting trot it'll be so easy, I much rather sit then post... sitting the extended is a different story though!
