Squat For Power To begin the downswing, I squat to create leverage. The squat disappears as my left leg straightens, however. This move creates tremendous power and speed. My extra-long swing length results from bending my left arm and cupping the left wrist. It's all okay if I return to a squared potition at impact. To start my downswing, I employ a classic power lifter's squat position. To some, it appears I'm having a tug-of-war with the weight of the clubhead. this is very similar to pictures of the legendary Sam Snead at the same point in the swing. It's important to note that my body drops slightly due to the increase in knee flex as I yank on the handle of the club with my legs, stomach and trunk, not my hands. By primarily using my body, I can explode into the golf ball with everything I've got without any undue hand action.

Many amateurs are so consumed with anxiety about the incremental parts of the golf swing (grip, alignment, posture, setup, etc.) that they lose sight of the overall objective, which is to strike the ball squarely and forcefully. Let me suggest a method to alleviate this anxiety: Focus on the finish.
There are many keys to a powerful swing, and my number-one focus is to establish a powerful backswing coil. Notice how my left arm is parallel to the ground while the shaft is perpendicular to it. This position indicates a massive turn away from the ball and not a simple lifting of the club to the top (you can see my entire body stretching and straining to get turned). The coil is further enhanced by my left foot, which is firmly on the ground. This limits the amount I can turn my hips while still allowing me to rotate my shoulders as much as possible. Some other keys:

One of the first lessons most golfers learn is to “keep your eye on the ball.” I’m here to offer a better suggestion: Move your eyes behind the ball.
You can’t hit big drives if your body gets stuck. That’s why I make a point of rotating my hips completely open on the downswing. This allows my arms to fully extend through the hitting area. Not only do my hips clear, but they remain level, which is key. By rotating through on a level plane, my right shoulder, arm and hip are able to continue adding power through impact. This prevents my body from getting stuck, which would limit the potential for clubhead speed by forcing me to hit only with my hands.

I’m frequently approached at my power clinics and exhibitions by senior golfers who claim they’ve lost strength and suppleness, which translates into shorter tee shots. My advice to them for regaining lost distance is simple and direct: preload your power. By that I mean seniors should make a few swing adjustments to compensate for advancing age and a diminished ability to turn their shoulders and torque their torso.
One of the keys to a solid golf swing is a level turn of the shoulders and hips during the backswing. A solid rotation not only promotes consistent ballstriking, but lays the foundation for achieving maximum distance as well.
