This has an added benefit. Besides strengthening my legs, and improving my balance, Grey and I get to work through his urge to take advantage of a loose seat or any movements that are out of the ordinary. He has a rather evil sense of humor when he feels me loosen up, and is overall a rather silly guy. Now and then I try bareback, but it can get a little tricky.
Up until I was in my late teens, and got into Saddlebred show horses exclusively, I rode bareback a LOT. The horse is not as wide as I remember.
