I have an open stance, semi-western topspin forehand. when i want to hit a powerful forehand, i coil by pivoting over the right foot excessively but when i lift up and jump, i see myself turning more than 90 degrees. When i land on my left foot, it's like i'm looking the opponent over my right shoulder and he can see my back. That comes unconsciously but destroys everything. I don't know if i should begin with limiting my uncoiling consciously or coiling weaker. You have any suggestions for me to prevent it ?
