it just hit me like a tonne of bricks !!! in the last few minutes,
after spending time today (at work ), swinging a yard & a half long piece of aluminium shaft ( basically a Dowel equivelant )... it hit me..what i should be trying to achieve in a golf swing.
view the left arm, club shaft, club head, right arm...as a structure, much like a you might view some scaffolding as a structure.... and use the pivot to propel the 'structure' backwards in the backswing.and then forwards in the downswing ...alll on plane of course...BUT..the important piece being..that the "structure" never changes! ( apart from the bend aquired in the right wrist in the take-away/ backswing ...and the cocking/ uncocking of the left wrist/right elbow )...but the overall structure does NOTHING, it is propelled by the pivot and remains in its shape.
hope this helps....cos this image/concept has sure helped me.
