Hip Turn / Action + Knee Action

[dd1979]

Anyone,

Could someone describe / explain the motion of the hips and the knees for me. i have been trying to (unsuccessfully) use standard knee action with a shiftless turn and delayed hip action. I would assume that as the right leg straightens and the left leg bends the right hip would be higher than the left? however, my hips seem to level out as the shoulder turn and the club moves to the top. then as I tranition into the downswing the right hip 'pops over the top' and I get a sagging look to my leg action instead of my attempted Sam Snead sit down position. Any explanations would be appreciated.
