UPDATE: Here is a link to my new video on the Arm Swing Illusion, released on July 15, 2015. For those of you who find this illusion concept fascinating and helpful, whether you intend to continue on in your reading and study of this mega-thread, consider buying the video (available from our website as a convenient download) and watching it several times. It is designed to be as close as possible to the actual experience of a live golf school with me, and is a total viewing time of 2 hours and 42 minutes. It covers the arm swing illusion, as well as several related illusions, in depth. The video consists of an Introduction to the basic concept, drills for de-constructing the Illusion from your subconscious mind swing map that are done without a golf ball, and finally drills you can do with a ball during range practice.
Any golfer who watches this video with a truly open mind will come away with a radical new understanding of what is actually happening in the modern tour pro golf swing. It is a mind-blowing experience that will challenge your previously un-questioned basic assumptions about what should be happening with the arm motion in a good golf swing. If you struggle with sucking the arms and club way inside the ideal plane in the backswing, over the top move during Transition, early wrist c0ck release and flipping, and arm dis-connection during Release, this video will show you the primary root cause of those Fatal Flaws.
And here is a small sample of that video: https://www.youtube....XUy5KN8AYM#t=24
We have completed the follow up video to that Arm Swing Illusion video: "Module Three - Advanced Arm Mechanics and Educated Hands" in two parts, a nearly three hour video Part A and a 40 minute video Part B. Both are available for download at the above link to our website. Module Three goes into a very detailed and technical explanation of the proper arm mechanics, and covers the Triangle concept, the Three Arm Pressures, more on the arm swing illusion, both swing map, slow motion mirror and ballstriking drills focusing on proper arm mechanics. Module Three also covers Elements Five through Nine of Educated Hands in the Balance Point System having to do with various forms of pressure, and awareness of hand path, clubhead weight, etc.
Module Four: Mechanics of the Pivot video is now available from our site as well. http://www.balancepointgolf.com/index.php/pro-shop.
Once you have a clear understanding of how the arms should work from Modules Two and Three, the next step is to learn about the basic elements of the Pivot: lateral weight shift on the forward swing, rotation, side tilt, forward Spine Angle, Tilt Illusion, Power sources, Pivot Thrust, Transition Trigger and related elements.
My e-book "Great Shot! Mastering the Craft of Ballstriking" also covers the Arm Swing Illusion material, but more importantly is a 205 page "encyclopedia" about the modern golf swing fundamentals, including sections on how to learn and practice effectively. http://www.balancepo...ro-shop/e-books
Thanks, Kiwi, for explaining that. The arms pushaway on a 45 degree angle to the chest, while the chest is rotating, in an actual golf swing. But - when we first present the Illusion concept in our golf schools, we do an exaggeration drill where there is no Pivot, to show what the arms actually do in relation to the chest, and in that drill, a club is placed on the ground from the middle of one's stance on a 45 degree angle to one's right. We practice the arm pushaway action which results in the golf club in one's hands being over the shaft on the ground, and the club in one's hands parallel to the ground, with just a touch of wrist hinge and c0ck as well. Then - we do the chest/belly Pivot with arms across the chest to around 45 degrees of chest rotation. Then we combine the arm 45 angle pushaway with the chest rotation for a perfectly on-plane takeaway or moveaway motion. The blending of the two motions is the key to a real takeaway.
Russc - you are taking connection too literally. You can have the left tricep touching the pecs while the upper left arm is moving on that angle to the right of mid-line a bit. We call it "connection in motion". And it happens for most of my students after the first third or so of the actual moveaway segment. Although you could certainly do it right from the start and still keep the upper left arm touching the pec as you start to do the pushaway motion. I recommend that option for some students who are way too inside with their arms during moveaway. You just have to synchronize the two at the right speed - otherwise you will get a seperation of the left arm from the pec.
