To dramatically help you improve the quality of your golf game, a good warm up is essential. A good way to start warming up is to practice the body rotation.
Start by holding a club across your shoulders and standing upright. Rotate the club, along with your shoulders and hips, back and forth around your spinal axis and in a horizontal plane. Make sure your body follows through until you face forwards.
Then lean forwards from your hips, take your set-up position and continue to turn around your spinal axis to practice the correct body rotation for your swing. If you feel your hands are not releasing the club enough to allow the head to pass freely through the ball, take your grip and then hold the club horizontally in front of your body.
Start to swing the club around you, backwards and forwards, with a relaxed rotation of your hands and body. The club head will stay at a constant height above the ground throughout the swing, if you are turning correctly.
So practice body rotations as a warm up in golf, and reap the benefits.
