Right before the canter starts you can see me tip forward and dump my hips out behind
Trying to rise up instead of swinging under
Additionally this time I got to discover I really don't know how to post. Theoretically I understand, but putting that theory into reality isn't happening. There is some sort of disconnect, which I texted my trainer "I don't understand how to post without tipping forward. Help." And being the amazing trainer she is, she didn't bat an eye and said "Of course!"
Don't let that face fool you, he broke a lead rope and took 45 minutes to load
The next time I rode with her, trainer tossed me up on her very nice upper level horse to teach me how to post. He is super steady in the bridle but also very sensitive so I could very easily feel the difference in his trot when my hips were under me and when I was letting them trail out behind. It really helped me get the feel for swinging my seat forward instead of up.
