So, here are the circumstances:
You're the second person ever on a green 2-3y/o who has only about 3 true "rides" on him.
You are riding in a saddle that is 2" too big for you.
The stirrups are WAY too long and end under your foot and you can't adjust them.
What do you do? This has been ruining my riding posture for so long, but I deal with it because it's the only way I get an opportunity to ride. Recently I've bought myself a saddle, but I'll still have to do this until the horse is up to the point where I would trust them not to ruin a new saddle.
Also I would like to know if anyone knows of ways to improve balance and postion and all that good stuff besides riding w/o stirrups or bareback (not allowed to do that on the colts.)
