The pump drill is one of the simplest, most effective ways to rebuild your downswing sequence and cure an over-the-top move. By rehearsing the transition in slow motion before you swing, you teach your body to drop the club into the slot and deliver it from the inside. Here is exactly how to do the pump drill and make it stick.
What Is the Pump Drill?
The pump drill is a rehearsal move you perform at the top of your backswing. Instead of firing straight into the ball, you “pump” the club halfway down toward the delivery position two or three times, feeling the arms drop and the club shallow, before finally completing the swing. It grooves the correct first move of the downswing by repeating it in isolation, slowly, until it becomes automatic.
Because it separates the transition from the rest of the swing, the pump drill lets you feel a movement that normally happens in a fraction of a second. That awareness is what turns a fault you cannot control into a motion you own.
What the Pump Drill Fixes
The drill targets the single most common amateur fault: the over-the-top move, where the upper body and arms throw the club outward at the start of the downswing, producing a steep, out-to-in path, slices, and pulls. If that pattern sounds familiar, pair this drill with our full breakdown of how to stop coming over the top.
It also helps three related problems. It discourages casting, where the wrists unhinge too early and waste power; if you struggle there, our guide on how to stop casting the golf club explains the causes in depth. It teaches the club to shallow in the downswing, and it helps you retain and create lag for more effortless speed.
How to Do the Pump Drill: Step by Step
1. Set Up and Swing to the Top
Take a mid-iron and set up to a ball as normal. Make a smooth, unhurried backswing to the top and pause there. There is no rush; the drill is about feel, not speed. Keep your grip pressure light so the club can move freely.
2. Pump Down to Waist Height
From the top, start the downswing by shifting pressure into your lead foot and letting the arms drop straight down toward your trail hip. Stop when your hands reach waist height. At this halfway point the club shaft should point roughly parallel to the target line, with the butt of the club aiming down at the ball, not out beyond it. This is the “slot.”
3. Pump Back Up and Repeat
Return the club to the top and repeat the pump two or three times. Each rep, feel the trail elbow tuck in front of the hip and the clubhead fall behind your hands. You are rehearsing the sensation of the club dropping to the inside rather than being thrown over the top.
4. On the Final Pump, Swing Through
After your last pump reaches the slot, continue smoothly through impact and into a full finish, striking the ball. Try to reproduce the exact path you just rehearsed. Start at half speed and build up only as the motion feels repeatable.
Building It Into a Full Swing
The goal is to transfer the feel of the pump into your real swing without the pause. Work through a simple progression. Hit five balls doing the full two-pump rehearsal, then five balls with a single pump, then five with just a tiny “bump” of the lead hip to trigger the same drop. Finally, hit five normal swings while recalling the feeling. If the over-the-top move creeps back, return to the two-pump version.
This sequencing works because it links the isolated move back to the whole action, which follows the proper order of the kinematic sequence: lower body, torso, arms, and club firing in turn from the ground up.
What a Good Pump Should Feel Like
Most golfers do the pump drill mechanically without knowing what success feels like, so it helps to name the sensations. As you pump down, your weight should move noticeably into the lead foot first, almost as if you are about to walk toward the target. A beat later the arms feel like they simply fall, heavy and relaxed, rather than being pulled. The trail elbow should brush past your side, and you should sense the clubhead lagging well behind your hands, still pointing up and back while the handle leads.
Crucially, your chest should feel like it stays closed, facing the ball or even slightly away from the target, for a fraction longer than instinct wants. That patience is what keeps the club on the inside. If instead you feel your shoulders and chest spinning open immediately, you are still throwing from the top and should slow the pump right down until the drop leads and the rotation follows. Groove that order and the ball flight changes on its own.
Common Mistakes to Avoid
- Pumping with the arms only: the drop should be driven by the lower body shifting and rotating, not by yanking the arms down. Start the pump from the ground up.
- Going too fast: speed hides the very fault you are trying to feel. Keep the pumps slow and deliberate.
- Over-shallowing: dropping the club too far behind you creates an in-to-out path and blocks or hooks. Aim for the shaft on the target line, not under it.
- Losing posture: keep your spine angle and knee flex steady through the pumps so the low point stays consistent.
- Skipping the strike: always finish the final rep by hitting a ball, or the new pattern will not transfer to real swings.
How Often to Practise
Rebuilding a downswing pattern takes repetition, so consistency beats volume. Spend the first ten balls of every range session on the pump drill before hitting normal shots. At home, you can rehearse the slow-motion pumps without a ball for a few minutes a day; the movement pattern is what you are training, and it grooves just as well in the living room as on the range.
Expect real change within two to three weeks of daily rehearsal. Deep-seated patterns fade gradually, so treat the occasional over-the-top swing as a cue to slow down and pump again, not as a failure.
Why the Over-the-Top Move Happens
Understanding why the fault appears makes the pump drill far more effective, because you know what you are correcting. The over-the-top move is almost always an instinctive attempt to hit at the ball with the strongest, most familiar muscles: the chest, shoulders, and arms. From the top, the brain says “throw,” and those big upper-body muscles fire first, spinning the shoulders open and shoving the club out and over the correct plane.
A second cause is poor sequencing. In an efficient swing the lower body starts the downswing while the club is still finishing the backswing, creating a brief stretch that lets the arms drop. Golfers who start everything together, or who lead with the trail shoulder, never earn that drop and are forced over the top. A weak or passive lower body compounds the problem: with nothing pulling from the ground, the arms take over by default. The pump drill retrains all three issues at once by forcing a ground-up start and a patient, inside path.
Three Pump Drill Variations
Once the basic pump feels comfortable, these variations reinforce the same pattern from different angles and stop the movement becoming stale.
- Headcover outside the ball: place a headcover an inch outside the ball on the target-line side. An over-the-top path clips the headcover; a proper drop from the slot misses it. This gives instant feedback on every pump and strike.
- Trail-arm-only pumps: grip the club with only your trail hand and pump slowly. Without the lead arm dominating, you feel the trail elbow tuck toward the hip, the exact move that shallows the club. Add the lead hand back once the feel is clear.
- Split-grip pumps: slide your hands a few inches apart on the grip and pump. The separation exaggerates the feeling of the club falling behind your hands and highlights any early casting, since the wrists cannot flip without you noticing.
Rotate through one variation per practice session rather than doing all three at once. Each isolates a slightly different sensation, and cycling them keeps your attention sharp while reinforcing the single goal of dropping the club into the slot.
Taking the Pump Drill to the Course
You cannot make two full pumps before a shot on the course, but you can carry the feel into your pre-shot routine. Take one slow rehearsal swing behind the ball, pumping into the slot once so your body recalls the pattern, then step in and swing while trusting it. Over time the drop becomes your default transition and the rehearsal is no longer needed.
The pump drill is proof that better ball-striking rarely comes from a new tip; it comes from rehearsing the right move until it is automatic. Start slow, lead with the lower body, feel the club fall into the slot, and let the improved path do the work.
