I have been focusing on riding with a softer arm this summer. One tool that has helped, particularly to keep that straight line from bit-hand-to elbow, is to ride with driving reins.
For those that haven’t heard of this, essentially the reins rather than coming up between you pinky and ring finger up through your index and thumb, you rather have the reins go through your thumb and index finger. For me this helps to keep a soft wrist and following hand. (I’ve attached a link that has a photo. I just googled “driving reins dressage” and this was a good image https://murdochmethod.com/no-56-holding-reins-like-driving-lines/ )
I believe there was one rider at Kentucky that rode like this in the dressage phase. Was it WIll Coleman ? What would be the cons of taking this position into the competition ring? I will sometimes incorporate this into my warm-up on my fussier TB before going back to holding reins as normal for the rest of my ride. But, are there any limitations of the driving rein as you progress up the levels?
Thanks!
