My friend took lessons as a kid, then more recently had several months of lessons, and now has her own horse. Unfortunately, her horse was lame for a bit and is in rehab. Right now she can do some walking around the arena, and that's about it (she can't even go on the trails, because the vet said not to do hills).
She doesn't want to take lessons again until her horse is better.
I know in my Dressage lessons we spent a TON of time at the walk, and I've passed on some of the activities I worked on. But as a beginner who isn't looking to show or anything, I think she might be getting a little bored and discouraged.
What kinds of things can I show her to keep her engaged and enjoying her horse?
