In simple terms, force plate data tells us how a golfer generates force from the ground up. 3D motion capture shows us how they deliver it to the club. A golfer can produce elite kinetics and still fail to maximize clubhead speed if their kinematics are inefficient. Two systems... show more

Many golfers believe that dialing back their swing speed is automatically going to produce a more controlled, technically sound swing. However, in reviewing motion-capture and force-plate data from elite players like Wyndham Clark, we often see the opposite is true. When we ask golfers to go after it, their data not only looks more athletic, they get a more dependable ball flight.

Optimizing ground reaction forces in the golf swing isn’t just about HOW HARD a golfer pushes against the ground, but HOW they push (timing and direction). One of the key kinetic variables we consider in a force analysis is called anterior-posterior force (or heel-toe force). Think of a golfer pushing frictionally against the ground, towards the target line with their lead leg and away from the target line with their trail leg. AP force is not only a meaningful contributor to clubhead speed, it also has a strong relationship to early extension. In order to prevent the pelvis from moving closer to the target line on the downswing, the lead leg needs to push considerably harder than the trail leg to drive the hip back (we often see over 2X AP force on the lead side vs the trail side in elite ball-strikers). As Newton outlines in his 3rd law, “for every action there is an equal and opposite reaction.” In the case of this PGA TOUR player, the trail leg was pushing equal to the lead leg, resulting in him early extending.

Working with Tom Hoge and his team to see how he might be able to find a few more mph ball speed with the driver. Whenever evaluating opportunities to improve speed, we consider three primary variables: 1) the size of an athlete’s “engine” by screening movement, strength and power; 2) their ability to generate force by assessing kinetics; and 3) analyzing how they deliver energy to the club by looking at kinematics.

How a golfer sees the target can influence how they set up to it. As Dr. Rose explains, same-side dominant players tend to putt with the ball slightly farther back and their stance slightly open. These preferences can help them see the ball and hole more comfortably. We teach simple visual system assessments in our Golf and Medical Level 3 seminars because they help us understand why a golfer might favor a particular setup. The better we understand why a golfer does something, the better we can determine what, if anything, needs to change.

Whenever a golfer comes to us asking for more speed, we start by answering a single question: is the gap between their current ball speed and their potential ceiling a mechanical, physical, or equipment issue? Teaching golf instructors, fitness and medical professionals how to evaluate problems like this is one of the foundational goals of our advanced course curriculum. By developing assessment skills for movement capabilities, physical capacity, force production and 3D mechanics, they can turn that question into a clear, traceable plan for every athlete they work with.

Many golfers are wearing shoes that are too long because they’ve added length when they actually needed more width. We’ve tested hundreds of golfers on force plates, and shoe fit is a detail worth checking. If the foot slides forward excessively inside the shoe, it can affect both the amount and timing of force a golfer applies to the ground.

How does waterskiing explain why early extension can prevent a golfer from reaching their ball speed potential? Think of a relationship between a ski boat and a skier. If the boat turns “away” from the skier, the skier accelerates. If the boat turns towards the skier, it creates slack in the rope and the skier slows down. If a golfer is thrusting excessively towards the target line, it may promote “slack” in the line. Many of the most powerful golfers in the world are actually moving away on the downswing, helping to accelerate the club.

One of the kinematic variables that stands out in Aldrich Potgieter’s 3D data is his ability to create lag and delay release in the downswing. While we generally don’t cue golfers to hold lag, research suggests that late-release in the downswing is closely associated with clubhead speed. Aldrich does this as well as anyone on TOUR. High-handicappers who cast the club and drag the handle, do not. If ground reaction forces are a good indication of how a golfer gets energy “into the system,” the ability to create lag is one of the ways they “transfer it to the club.” In our experience, the ability to create lag is aided by elite sequencing. Golfers that are able to initiate their downswing by pelvis -> trunk -> lead arm often create lag more efficiently. This is why we say we don’t coach lag, we coach movement.

128mph club head speed & 190mph ball speed. If you listened to my podcast with Young-Hoo Kwon you will have heard him talk a lot about lateral and vertical motion in the swing (especially when speed is the goal). Summary (for maximizing your speed) : Shift right and up early in the backswing. Fall left and down in transition Then absolutely smash it I would have liked to see force plate data from this one. To any of the coaches / speed enthusiasts following, where can I improve for 200mph 😎😬?

Back leg angles 🔑 We just did a breakdown on what it takes to throw hard as an undersized pitcher. On top of maximizing mass for your frame and trunk rotational velocity, we talked a lot about ground force. Specifically, not just how to maximize the back leg impulse (how much force and how long you can hold it), but how the angle of this ground force plays a major role in whether it actually increases your momentum towards the target.

Hyliion's Stirling engine technology just landed a major military contract. Thomas Healy of Hyliion tells Remy Blaire their system powers the new US Navy's unmanned autonomous ship, designed to run a full year without any maintenance. "That's a game changer in terms of how the military looks at how they can produce electricity."

Up till now i still can’t figure out how Chelsea was able to beat us in the club World Cup. They stopped us from a historic septuple in one season.

From my research, the biggest driver of clubhead speed is the average force applied along the hand path. When I first started working with Matt Fitzpatrick, this was a key area I wanted to improve—but explaining it in biomechanics terms would have been suboptimal. So I translated it. Draw Early. Fade Late. It’s a simple feel that captures how force should be applied throughout the swing—and it’s been a big piece of unlocking speed for many golfers.

Many amateurs wait until the top of the backswing to initiate the downswing. Elite players do not. When we look at force plate data from the best ball strikers in the world, the majority begin pushing against the ground well before the backswing is complete. These ground reaction forces help decelerate the pelvis so the player can lead with the lower body on the downswing. Force precedes motion. New video on our YouTube channel. Link below

One of the most common speed leaks in the golf swing can be the product of improperly fit equipment, but it isn’t always related to clubs. It can be the shoes. If a golfer’s foot is sliding inside their shoe during the swing, it can affect their interaction with the ground and “dampen” the ground reaction forces that help generate greater clubhead speed. Fit matters, especially in our footwear. Full video with FootJoy on YouTube.

A golfer’s ability to use the ground effectively is critical for maintaining dynamic posture and avoiding swing characteristics like early extension. In order to prevent the pelvis from moving closer to the target line on the downswing, golfers must push aggressively against the ground with their lead leg, both down (vertical force) and away (anterior-posterior force). One of our favorite strategies for helping a golfer develop a feel of creating these forces is a series of medical ball throws. By cueing athletes to focus on the timing and direction of their ground reaction forces, we can teach them to “use their legs to drive their arms” and avoid thrusting towards the ball.

This was the take down operation for the arrest of Matipandile Sotheni, the accused in the murder of Marius van den Merwe, Witness D in the #MadlangaCommission. Sotheni was a member of the Elite Task Force. The operation was conducted by Task Force members, overseen by General Mkhwanazi. You see him in a white Tshirt. The speed ad precision tells shows you how highly trained they are and knew they were dealing with someone as trained as they are. The General expressed sadness and disappoinment that they had to arrest one of their own, someone who trained and qualified under him. He brought shame to the prestigious badge.

Total torque has one of the strongest correlations to clubhead speed of any kinetic variable in our database. Since torque is a product of force and moment arm, we can increase torque in the golf swing by either pushing against the ground with more force or pushing further away from the center of rotation. Think about pushing a heavy door open. The further you push from the hinges, the easier it is to move the door. You’ve increased the “moment arm.” Increasing force is a gym intervention. Increasing moment arm is coaching intervention.
