Lexi Thompson's Golf Swing: A Great Example of Downswing "Separation"

Published: March 2, 2026

If you've ever wondered what good upper body-lower body separation in the golf swing looks like or how to achieve it, this analysis of Lexi Thompson's golf swing may be just what your swing needs.

As you likely know, Thompson recently became the youngest winner ever on the LPGA Tour.

She also averaged over 275 yards per drive for the week, which would easily place her among the longest hitters on Tour — a testament to her exceptional swing mechanics and power generation.

To pick up some extra yards of your own, you should pay great attention to Thompson's transition move, which you can see in the pictures (and full video analysis) below. You can also use an AI swing analyzer to measure how well your own transition compares to elite players.

The images make it clear that she does a great job demonstrating the RST principle of starting the downswing with the lower body and keeping the trail shoulder quiet through transition.

This upper-lower body separation is the hallmark of all long-hitting pros — they initiate the downswing by driving the lead hip toward the target while the trail shoulder remains back, creating a powerful rotational lag that translates directly into clubhead speed.

This is the separation all long-hitting pros create and what you should strive for in the RST. The GOAT Drill system is specifically designed to train this exact lower body lead and hip-shoulder separation pattern through measurable, repeatable reps.

Check out the video below to get some tips on how you can incorporate this move into your own swing while also learning which of Thompson's moves you'll want to avoid — and how to use intentional practice to ingrain the correct kinematic sequence for maximum distance.
