As someone who rode in the 80s, quit and started up again in 2011, I noticed that a LOT of things have changed/are different now.
For example, in the 80s riding instructors used to preach at us about pinching with the knees. The harder and longer you could pinch, the better. Now riding instructors are advocating for a soft knee, that softly drapes around the horse.
What are some of the changes/differences you have noticed?
