Hitting behind on wedges

[mtibt]

There is a tendency on wedges to stoop over. Stand up straight with normal posture, grip down on the club depending on how far you want the shot to go, and, get your wrists to remain dead. Getting wristy has ruined more wedge shots than anything else, just let the loft of the club go through the ball without decelerating which is a big tendency.
Hope this helps.
