One of the most overlooked 'actions' in a swinger's motion is the bent right wrist. During a swing the left wrist only cocks and uncocks (via the right forearm) and the right wrist only bends.
EdZ, I have a problem with that procedure. I don't disagree, but I'm unable to do it. I've been very successful with Start-up Swivel, but my Right Wrist Bends as my Left Wrist Flattens only during the Release Swivel. I don't want to change my procedure but I would really like to understand why I can't swing with my Right Wrist Bent throughout the swing as you recommend and as I have tried for so many years.
If my problem is obvious, please tell me. Otherwise, I'll continue many more years suffering tortuous research to learn and find the answer. Which, by the way, is quite familiar to me.
