You don’t need to be built like a linebacker to launch bombs off the tee. Just ask Justin Thomas — 5’10”, 160 pounds soaking wet — who regularly rips it over 300 yards. How? Not because he swings harder. Because he swings smarter.
Let’s break down what JT does differently, and more importantly, how you can steal a little bit of that secret sauce for your own game.
He Squats to Jump — Literally
Most of us try to stay tall in the backswing. JT? He drops. From address to the top of his backswing, he lowers himself by 6–7 inches. That squat is the key to what comes next: a full-on vertical push through impact.
By pressing hard into the ground with both legs — especially the lead one — JT generates explosive upward force. His body actually lifts off the ground at impact. And no, it’s not just for show. That momentary “air time” means he’s maximizing energy transfer to the ball.
Swing studies show he creates over 2.5x his body weight in vertical force before contact. For context? That’s like launching yourself with the strength of a kangaroo… while hitting a golf ball.
Hips That Don’t Lie (They Rotate)
Where amateurs slide, JT rotates.
His downswing starts with a lightning-quick firing of the trail hip. But here’s where it gets wild — instead of bumping the front hip toward the target, he pulls it back, creating external rotation in the lead leg.
Think about that move you do when you try to shake out tight hips at the gym — now add 118 mph of clubhead speed to it.
That aggressive hip clearing, combined with a tilt of the left pelvis, gives JT the torque to unwind like a spring. And here’s the kicker: his back heel lifts early, letting the trail hip fire with max intensity.
Want to feel that kind of rotation yourself? Try this:
The Basket Drill
- Place two baskets behind your front leg.
- Take a few swings trying to knock them over — using hip rotation, not a side slide.
- If you’re sliding and not rotating, the baskets stay put. That’s your cue to fix it.
The Arm-Chest “Squeeze” at Impact
While the legs and hips do the heavy lifting, JT’s upper body knows its job too.
At impact, he maintains a tight connection between his lead arm and chest — what coaches call the “maximum squeeze.” This ensures he’s not dragging the handle through (which kills distance) and keeps energy moving through the ball, not around it.
It’s like he’s hugging the power in — and then releasing it right into the back of the ball.
Timing: The Real Secret Ingredient
The real magic isn’t any one move — it’s the sequence.
JT starts shifting his weight before the backswing even ends. That separation between upper and lower body stores elastic energy. It’s the same kinetic chain you see in pitchers and quarterbacks — and it’s why his swing looks so effortless, even though it’s anything but.
He also keeps his trail elbow tucked and swing arc narrow in the downswing, which boosts clubhead speed. Combine that with a wide backswing turn, and you’ve got max torque in a small, powerful package.
Want to Try It? Here’s How
These drills help you feel what JT feels — without needing to jump off the ground like a maniac (though… it helps).
1. The JT Jump Drill
- Take your normal stance.
- Swing and intentionally jump at impact.
- Focus on pushing into the ground and coming up on your toes.
- Key tip: the lower you squat before the downswing, the higher (and faster) you can spring up through impact.
2. Vertical Force Reps
- Load into your trail side at the top.
- Transition to your lead side while straightening the front leg.
- Feel like you’re stomping into the ground, then driving up and around.
3. Three-Piece Position Check
- Break your swing into three checkpoints.
- Pause and align at each one — takeaway, halfway back, full top.
- This builds awareness of your sequencing (and kills bad habits you didn’t even know you had).
JT isn’t long because he’s big. He’s long because his swing is efficient.
He uses the ground, rotates like a coil, and times every move with ridiculous precision. And while we can’t all jump like him, we can steal the principles behind that pop.
You don’t need to swing harder — you just need to learn how to use what you’ve got, better.
