Whip up more Speed
Imagine there’s a whip connected at the club head. To get the whip to crack at the bottom of your swing, you must “snap” your wrists and hands through the strike without over swinging your shoulders. Here, I’ve attached a piece of ribbon to the shaft. (It’s a lot safer than an actual whip.) The trick is to consciously get the end of the ribbon to “crack” right at the bottom of your swing arc.
This drill is a great way to take your mind off hitting balls, and instead hone in on increasing your club head speed.
