Oh my, when I tried english, I HATED contact. It was always "Michaela, more contact!" throughout lessons. My jumping instructor HATED me for it
One of the things most people know how to do, and I never got the hang of it. I always had the "Get off his face, get off his face..." mindset. I found the transition to english too hard and I didn't have the love of it to try hard enough to get it down. So I went back to doing what I knew, lol.
If this little guy is a reiner, remember when you say "whoa" to keep your feet out of his way. Sit on your pockets and kick your feet forward. A real reiner won't stop with your feet touching them, it'll put them on the front end.
The neck rein is just joyous when you get it down...I love a loose rein, head low, bumping up from behind, soft horse :)
Maybe watch some videos of how some reiners ride. Get a feel for that body position from seeing it.
