What is Attcak Angle ?

Measured relative to the horizon, Attack Angle is the up or down movement of the club head at the time of maximum compression.

Golf shots hit off the ground (not off tees) should have a negative Attack Angle to optimize trajectory.

However, golfers with slower club speeds should be careful not to hit too much down (negative Attack Angle) with their irons. This will affect the golfer's potential distance as well as their ability to control the ball on approach shots.

To maximize distance with your driver, hitting up on the ball (positive Attack Angle) is a must. The driver's loft should be chosen so that it complements the golfer's Attack Angle and club speed. Having a positive Attack Angle does not guarantee maximum distance. The fit of the club is also an essential piece of the puzzle.
