Many golfers I teach have a difficult time starting their forward-swing. What I usually see is that as they get to the top they have a violent move to start the swing down and after they hit the golf ball they fall out of balance. What you want to do in the golf swing is have a gradual acceleration when you start down.
Gradual Acceleration on the Downswing
If I let this club go it starts down slow and then builds up speed. Its maximum speed is down by the bottom of the swing arc. The same thing is true in golf as I swing the club back, and when I come down, it is a gradual acceleration. If I want to build a 100 miles per hour of clubhead speed at impact, the way I do it is, as I swing to the top, I gradually start down with slow speed and I let all my speed occur at impact.
Maximum Speed: Bottom of the Swing
Just like if I let this club go, when I let it go, it starts slow and its maximum speed is down by the bottom. I want you to do the same thing when you're hitting a golf ball. When you start down from the top with your arms and your body, it's a gradual acceleration, then building the speed up at the golf ball. And it's the same for every club. I'd like to demonstrate one for you. With a three-wood, I'm just going to have a gradual acceleration as I start my forward-swing. If you can learn to do that with every club in your bag, you're going to play a better round of golf.
