Bottom Rib Backswing

A great way to work on sequencing is to make a backswing, pause and collect your thoughts of what you want to do and then execute that movement. In this case, the normal thing to work on with the hit from the top is starting the downswing with the lower body. This drill is especially challenging for golfers who want to pull hard on the handle with their arms because typically they won't have the same amount of lunge to balance the pull. 

hit from the top is also a great way to work on specific movements of the arms. If your sequencing is good, you should have no problem hitting it solidly from a dead stop. The part of your swing that will typically suffer in this form of training is your distance.
