This is a simple riding stretch I have done for years, it helps with my confidence, balance and muscle memory.
Which was good earlier this week when Buttercup bucked. I found myself face downward over left shoulder and having lost my left stirrup. I was able to return to return to sitting position because of muscle memory.
While horse is standing quietly, right hand to poll, dock, right toes then left toes (much easier 40 years ago.) Repeat with left hand. Work up to doing them while horse walks quietly. The Aging Horsewoman.
