This post is part of a series of discussions where I tackle a lot of common swing issues. However, instead of providing common fixes that you've probably seen elsewhere, I will be providing a more accurate way to think about how to obtain the correct feels of the swing. This series is catered to help more of an intermediate to advanced player who has somewhat of a functioning swing. These articles will assume you know some swing vocabulary.
Today we will be discussing a Power Leak that happens when your legs don't work correctly:
How it's different: This tip is different because the legs play a crucial role in providing power in the swing. Many people know that the legs act as resistance, but there is big myth that's killing swings out there which is the tip that tells you to twist your hips back.
There's a plethora of misleading articles and Youtube videos that talk about getting more hip turn and hip depth on the backswing. This information targets golfer's inflexibility and advises golfers to purposely twist the hips back to get into an overly excessive internally rotated hip position. This type of motion will most definitely lead to a loss of power because it decreases your vertical ground force and increases a sort of torsional sheer force in your feet. He is an example of an overly level and improper hip rotation. Notice how this golfer's left hip is really high and turned a lot more level.
What does this have to do with leg motion. well, you legs along with your hips play a vital roll in creating proper loading to the trail side of your body. Without your legs working properly, it will be difficult to get your body to tilt properly and create leverage into the ground. Here is what more of the proper hip tilt should look like:
HereNotice how Rory's right hip is much more higher than his left. Pound for pound, Rory Mcilroy generates a ton of club head speed compared to others on his size on the PGA tour.
However, today we're going to specifically address how the hips work by addressing more of an uncommon fix: The correct use of the legs. The correct sequence of leg work starts with the golfer pushing off the lead leg to put pressure into the trail leg. What you sense as weight shift will build during your backswing more toward the inner heel of you trail leg as your knee straightens. You'll feel as though your slightly straightening your trail leg and pressure will build under your trail heel more specifically. In tandem with this move you'll feel an unweighting of your left leg and your left heel which you will drive back into the ground with tremendous force. This build up is what you body uses as leverage to drive into the ground with your upper body. This is also at about shaft parallel in the downswing is where your ground reaction force should be at it's highest. If you get this motion right, look for an increase in your power and swing speed.
