The Importance of Alignment
One of the most common problems my students come to me with is poor alignment.. The absence of consistent alignment causes many swing compensations where the player is attempting to make the ball go to the target.
If the student is aimed left, they will attempt a swing to make the ball go back to the right and toward the target. The swing faults associated with alignment too far left are weak grip positions, open clubface positions, overly inside out swing paths, and clearing with the body early or coming out of the shot. All of these motions are out of athletic balance and will cause weak fades, slices or push shots not to mention poor contact and distance will be reduced, as it is a weaker hit. The student will be quite possibly one of the shorter hitters in the group.
Likewise, if the student is aimed right, they will have just the opposite problems with their swing. The swing faults associated with alignment too far right are closed clubface positions, strong grip positions, outside to in swing paths, and staying on their back foot letting their arms pass their body faster than what is recommended. The product of these out of balance swing faults will be pulled shots, hooked shots, topping the ball or hitting the ground first before the ball,
and yes, the dreaded shank
. This person is likely to be a long hitter with short to mid irons, but can struggle with long irons, some fairway clubs and Driver.
