Got that from Dana, did you?
I also work on elbows together.
I am working on some 5SK Moves -- roll up the toes, and roll the ankles to get the weight FORWARD.
The drills were very helpful.
I always work on my big bugaboo - which is keeping the trailing elbow at the shirt seem and not behind it - trying to feel as if my right arm does not bend (so my arms feel more in front of me) and putting pressure onto the left thumb.
