Sorry Yoda. I am not magnifying my split hair well enough! How does one attempt to straighten the right arm (extensor action) while bending the elbow (push basic)? I swing and do not use #1Acc, except on the greens. I understand (I am pretty sure) how the left arm checkrein causes the right arm to bend as it moves closer to the right shoulder. With push basic it is just the right elbow bending and unbending (while it attempts to remain straight? )
