I have recently Just posted another similar thread under golf machine basic, sectoin, but i am having great dificulty with my weight shift, i was on a dynamic balance machine today, and i saw that my weight was shifting way to far back onto my heels and even behing them on the backswing, and the main problem is way way to dar out onto myleft toe at impact, coming out of my psture, thrusitng my hips towards the ball, no matter how hard i try i was unable to stop the weight shift issue, but on video was able to stay down in the shot however it was a great struglle. I thinkthat htis may at least be partly a physical conditioning issue, any exersizes to help get through the ball better woudl really help. I constnatly struggle to usemy hips and keep them goeing to keep the lag and drag in the pivot train, as they seem to want to stop prematurly, and the overtaing begins way to soon, causing an array of swing flaws the biggest of which is runningout of right arm and then beding my leading wrist.
