드라이버 비거리 무조건 늘어납니다. "이 원리"를 알면 볼스피드 100% 빨라집니다. 죽어라 연습해보세요.

Key Summary: The reason you relax your muscles at address and during the backswing is to ensure the timing is right for releasing during the downswing. Impact is something that happens naturally. All we have to do is release, and that is it. The Key to Distance: While you apply acceleration, deceleration (releasing) is more important. Try to focus on releasing the momentum while accelerating in a state of weightlessness. Do not rotate your body blindly; instead, decelerate to some extent (hold your ground) and "synchronize" with the clubhead following behind at impact. If you release the momentum and the clubhead feels heavy and seems to be dragging along, that indicates the acceleration and deceleration have been properly executed and synchronized within the swing. This is the secret to hitting the ball incredibly far with a relaxed, light tap.
