Lower Body Stability Swing Faults
Good Lower Body Stability
A stable lower body will create a consistent and powerful golf swing. The keys to a stable lower body are:
Adequate width of stance.
Knees over big toes at address.
Stable trail leg through the backswing.
Stable lead knee through the backswing.
No early extension (forward thrusting of the pelvis) of the pelvis at impact
Narrow Stance Fault
Having the appropriate width of stance promotes stability and power in the golf swing. Your stance should become wider the longer the club. The reason for a wider stance is to generate stability. As you swing faster with longer clubs you need the ability to stabilize the lower body through a wider stance.
Caved In Knees At Address Fault
You might think caving your knees in at address helps with rotation and stability. It actually isn’t good for your knees, and decreases rotation. This causes a lot of inward pressure of the knee and promotes bad rotation through the backswing and downswing. Having your knees over your big toe at address relieves pressure on the knees and brings stability.
Straight Trail Leg
A straight trail knee is a common style for some golf swings. However, if the trail knee straightens too much it can cause over rotation of the pelvis, and over swinging. If you over swing keep your trail knee flexed, and limit your lower body rotation. Having too much flex in the trail knee can cause squatting and lead to other problems.
Caved Lead Leg Fault
An inward collapsing lead knee is a very common lower body stability fault. When your lead knee collapses your upper body tilts the opposite direction. This creates another issue called reverse spine angle, and it’s the most common cause of back pain. Reverse spine angle isn’t just bad for your back. It’s also bad for:
Proper Downswing Transition
You will tend to notice that you are good with your short irons, but bad with long irons and woods.
Early Extension Fault
Early extension is the most common swing fault in golf. Early extension is the pelvis thrusting forward or “moving off the line” on the downswing. However, it can start at the top of the swing as well. Typically the pelvis is tucking under instead of rotating through the impact zone. The pelvis should stay “on the line / wall” through the impact zone. Good pelvis mechanics promotes:
Club Face Control
Early Extension can be caused by a number of things:
Unaware of Proper Mechanics
Tight Hamstrings and Calves
Unable to Pelvic Tilt
