The wrist in your golf swing can add some power to your shot. Your wrists are going to work differently depending on how you are swinging. In a two-plane golf swing what happens since you are taking the club straighter back is that the club does not tend to rotate on its own, so you really have to do a lot of wrist cock drills trying to get your wrists hinged. Some people will try a very early wrist cock when they are trying to swing on a two-plane way, but they are really trying intentionally to cock that wrist and rotate the golf club to get it on the angle or swing plane that we need. In a one-plane golf swing what happens is that the weight of the golf club tends to hinge your wrists naturally. When you are bent over and you are swinging the club on a diagonal line back to the inside like you do on a one-plane swing, the weight of the club tends to hinge your wrists back so you get some angle to your golf swing pretty naturally, it is almost like a flinging feeling. If I ever see a student and they do not have any wrist hinge in their swing it is a big trigger to check the tension level in the golf swing, if it is too tight they can not hinge their wrists. I check their grip, if they have too much of a palm grip the wrists will not hinge without their hands coming off so they will grab hold of the golf club, or I check the swing shape. Remember, if a person is swinging in a two-plane way there is really no wrist hinge that happens on its own, you have to make it happen. So again, one more reason why a one-plane swing might work better for you. It will activate some wrist action in your swing, set your angle and give you a little bit of power in a natural way.
