If you can build a good structured backswing, you can store a tremendous amount of energy to be unleashed in the forward motion. There are three 90 degree angles that if built properly, will make your backswing condition extremely powerful.

1) The right arm bend at the elbow should form a perfect 90 degree angle.

2) The shoulders should turn 90 degrees from address.

3) The left arm and club shaft should form a 90 degree angle at this time.
