It's just a different 90 degrees. :)

Lag is technique and the answer to "how do I get seemingly effortless - relative to hackers - power." It is not what powers the golf swing. It is what makes a swing powerful.

And, whats more, the spoke and spindle in human terms is not capable of generating anywhere near the clubhead speed that a flail could.

Listen for the "swoosh".

Repeat the process but with backswing torso rotation. Do you hear any difference in "swoosh" sound? No, I thought not, so what does that tell you?

Performing the same motions (Hitting) with your right arm only and your experience will be no different.

Barry does have amazing lag. Seeing this is very humbling and explains why I could never hit a softball very far in the corporate league. After all these years of golf, I could never imagine trying to be so open at impact. As a result, poor rotation. a quitting stroke to be sure.

Alternatively you may be misinterpreting somehow :roll: that I would be suggesting, after much discussion of flailing that the rigid structure of arms would remove flailing. This is not the case. Think extensor action.

If however you are suggesting that the firm attachment of the left arm to shoulder excludes the flailing of a flail formed by the lever from the spine to shoulder (roughly) and the left arm, that is true but a secondary effect in power generation.Golfie

A pitcher does this by standing his shoulders perpendicular to the batter, not have them parallel like in cricket which is a running throw. A pitcher must make a stride - a forward motion - down and off the “rubber.” In order to make this slide off and down the hill or the mound, the front leg must lift and step forward. This becomes a weight transfer, what baseball players call “putting the hip into the pitch.” The pitchers shoulders do become square to the batter after the front leg lands after the stride. The front leg movement, the pitcher’s stride, is the weight transfer, pivot and power package of the pitch. A good pitcher does not throw flat long throws. 60 feet 6 inches. The pitch will move downward from the top of a high hand release, the wrist snap puts a spin on the ball and if well executed will “break” off its path a few inches from the batters whirling bat. Strike one!

Our golfing flail requires no rotary motion to generate, and transfer, its power from top to bottom. This is done by the straightening of the assembly to its in-line condition: arm power in hitting and centripetal force in swinging.

As Homer was fond of reminding us, the golf swing is a body transported - not powered - arm swing.
