My legs do the same but a drill on here from Yoda really helped. It entails placing/attaching a dowel across your thighs. If your legs move to fast or incorrrectly you will hit the dowel with your club. I have never attached a dowel but played this weekend imagining the dowel there and dropping the hands/arms first so I don't hit the dowel really helped. It is a great image/drill. One that I will work on all winter. Have to figure out how to attach it however.

This is an excellent drill and likely the cure for you. Slide the dowel through your two front belt loops.

Hitting shots with your feet together, or as a better variation, with your trail foot crossed in front and feet together, are other drills that should help you quiet down your leg drive. Putting a small object (ball, piece of 2/4 etc) under the outside edge of your lead foot will really help you feel the 'post up' move, but use this with caution or you'll hurt your knee.

Often this goes along with being well under plane, so I would also suggest doing some plane line tracing.
