Step 1: Create Width. Step 2: Push away - transfering force away from the direction of the swing - not up. Step 3: Re-hinge the club; this requires relaxation, which increases speed.
Speed comes with control. Practice getting comfortable with the shots you are good at.
The motion of the golf swing is an unforgettable feeling. In the new year, learn to feel this motion.
The New Year is here, and being comfortable with all of your clubs is more important than ever.
