In our latest article, we break down the force plate data behind elite chipping and share the simple rule of thumb we use with players: the lower body must move forward, back, and up. mytpi.com/articles/swing…

In the full swing, we know the lead leg wins. In terms of lateral force, players in our professional database push with about 20% of their body weight with the trail leg, then the lead leg slams on the brakes at roughly -29%, converting lateral motion into rotational speed. But when we put elite chippers on force plates, the pattern completely flips. Around the greens, the "lateral brake" isn't big enough to stop the motion. The trail leg wins, and the best short game players in the world are moving their center of mass toward the target through the strike. High-handicappers, on the other hand, tend to stall or even fall away from it. That reverse pivot is where fat and thin contact comes from.

Knowing whether a swing characteristic is the product of a physical limitation or a technical issue is one of the most valuable insights for anyone working with golfers. After all, asking a golfer to do something they aren’t physically capable of doing is the recipe for a bad session. In addition to helping capture screen results, our TPI Pro app highlights how physical limitations may be affecting the swing and even recommends drills and exercises to address them. Assess, don’t guess.

@RossADixon Yeah, impossible to know without a diagnosis, but would be the first place we'd recommend looking.

I had si joint pain when I used to play as a pro. 24 years old and I struggled to get out of bed due to si joint pain. It was described to me as an inflammation pain. Strength training on the legs did help but I have always suffered from very tight hips. It seems they are the culprit.

Like many injuries, SI joint pain doesn’t always represent an SI joint problem. The SI joints are where the pelvic bones meet the sacrum. They are designed for STABILITY, not motion. The golf swing, however, demands rotation. Ideally, that rotation should come primarily from the ankles, hips, and thoracic spine. Lose mobility in any of those “mobile” areas, and your body goes hunting for rotation somewhere else, often twisting the pelvis through the SI joints. Considering the explosive and repetitive nature of the golf swing is, this excessive stress can eventually result in pain. The SI joint is usually the victim, not the culprit.

Congrats to Tom Kim on his victory at the Scottish Open, his fourth PGA TOUR win at just 24 years old. Training here with @ChiroSportTVB to build power and durability. Skill wins tournaments, but skill only shows up if the body can deliver it.

The transition mistake most amateurs make: “get to the top, then go.” By the time an elite player’s pelvis changes direction, the forces driving it started long before. mytpi.com/articles/swing…

The simplest way to look at the human body is as an alternating pattern of mobile and stable joints. If a golfer lacks mobility in an area that is designed to be mobile, the body just steals the rotation from the stable ones, often the lower back. Keep the mobile joints mobile.

@drakesmith__ Well said. Static positions aren't representative of what a golfer feels or how they are pushing. Obviously, can be a really helpful teaching tool, but somewhat limited

This is why I really don't like backswing positional work. At times it is necessary but it is not how you swing the club at speed. The backswing is not a destination it is a reaction to you moving to the target. Everything starts from the forces you produce from the ground up. When you get your body moving right and creating forces properly it is amazing how the positions are looking for start to happen.

Force Precedes Motion: The Transition Mistake Most Amateurs Make mytpi.com/articles/swing…

Elite ballstrikers don't wait until the top of the backswing to initiate the downswing. Dr. Rose and Dave Phillips demonstrate how one of the best players in the world begins pushing against the ground early in the backswing, and rotating his pelvis toward the target before the club reaches the top. It's Newton's First Law at work in the golf swing: force precedes motion. mytpi.com/articles/swing…

The Transition Mistake Most Amateurs Make youtu.be/VbvOSr_QDQw

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

Got it. Well, it wasn't a scripted clip. It's literally just 7 minutes of Greg and Ben demonstrating/talking about a feel that he liked and that helped produce a jump in CHS that day. Apologies if someone didn't get the credit they very much deserve, but we don't direct these interactions, we just document them youtu.be/bY9JhsD_wBU?si…

I think it’s disingenuous, if we’re being honest, the greatest jump in club speed statistically was after this period from 2023 on…when he was working with a non affiliated tpi instructor. No mention of this though

@TJYeatonGolf We also acknowledge in the post that dedicated speed training was an integral part of him swinging faster. On this day, he and Greg were messing with a feel in the bay and they saw a big jump so asked us to grab the camera. Apologies if you thought it was weird.

Ben Crane worked extensively with TPI for nearly a decade in his prime as a PGA Tour Player. Between 2008-2019 club speed ranged from 105 to a high of 110. It’s ironic they’re claiming these gain now in 2026. Weird

"It has become a more athletic endeavor... There is a lot of force that goes into creating a 125 mph clubhead speeds." There are many things to emulate from Justin Rose, including his commitment and sound approach in the gym.

Trail shoulder external rotation can be a key shallowing mechanism in the downswing. We evaluate a golfer’s external rotation mobility in two ways through our 90/90 Test: standing tall and in golf posture. If they have less external rotation in golf posture than standing tall, it indicates a potential issue with scapular stability. Assess, don’t guess. 🎥: @meandmygolf

3x U.S. Senior Open champion 🏆 Congrats to @padraig_h on a record-tying third title at Scioto. Here’s Padraig dialing into our Level 1 webinar a few years ago to talk about the importance of assessments as feedback for guiding training. Our Lower Quarter Rotation test takes about 30 seconds to complete, but the results can provide motivation for the athlete and accountability for the coach. Whether looking at movement quality or power capacity, why guess when you can assess?

100 days until Golf Level 3 at TPI. Three days at TPI headquarters with Dave Phillips, Dr. Greg Rose, and James Sieckmann, learning how to turn 3D biomechanics, force plate data, and physical screening into better coaching. Upcoming Level 3 events: Power Level 3: September 18th – 20th Golf Level 3: October 9th – 11th Fitness Level 3: November 6th – 8th Medical Level 3: December 11th – 13th
