If your freestyle catch feels weak or your hand slips through the water without grabbing anything, the fist drill is one of the fastest ways to fix it. Swum by everyone from age-group swimmers to Masters and triathletes, it’s a staple in pool workouts precisely because it forces your body to find a better catch on its own, without a coach shouting cues from the deck.
This guide walks through exactly how to swim the fist drill, sample sets to work it into practice, why it works, and how to fold it back into full-stroke freestyle so the improvement actually sticks. It also covers the mistakes that make the drill useless if you’re not careful.
Quick Answer
Swim freestyle with your hands closed into loose fists instead of open palms. With less surface area on your hand, you’re forced to catch and pull water with your forearm, which builds the early vertical forearm position and high-elbow catch that make freestyle efficient. Swim a length or two with fists, then switch back to open hands and try to keep the same forearm feel.
How to Swim the Fist Drill Step by Step
Start in the water and curl each hand into a loose, relaxed fist — don’t clench so hard that your wrist or forearm tenses up. Push off and swim freestyle exactly as you normally would, keeping your regular stroke rate, body rotation, and kick.
As you extend your arm forward at the front of the stroke, rotate your elbow outward slightly so your fist points toward the bottom of the pool and your forearm turns into a paddle. This is the ‘early vertical forearm’ position coaches talk about — your forearm should feel vertical, or close to it, well before your hand passes under your shoulder.
Pull through using your forearm and upper arm, not just your fist. Because your hand alone can’t generate much propulsion, you’ll immediately feel whether your elbow is staying high (good) or dropping toward the pool floor (a wasted stroke). A dropped, or ‘saggy,’ elbow at the start of the catch is one of the most common freestyle flaws, and it’s exactly what this drill exposes.
Swim a set distance with fists closed — commonly 25 yards/meters, or four to six lengths — then open your hands and swim the same distance at full stroke, trying to keep the identical forearm and elbow feel. Repeating this fist-then-open pattern several times per set is what transfers the drill into your real stroke.
Fist Drill Sets: How to Work It Into a Workout
There’s no single required format, but most swimmers and coaches build the fist drill into practice one of a few ways. The simplest is straight alternating 25s: swim 4 to 8 rounds of 25 fist / 25 open freestyle, resting 10 to 20 seconds between rounds so the forearm feel carries over cleanly.
Another common approach is dropping fist lengths inside a longer swim — for example, swim a 100 or 200 freestyle and close your fists for one 25 in the middle, or swim a 100 as drill-swim by 25s with fist as the opening 25. This keeps the drill connected to race-pace swimming instead of isolating it as a separate, slower rep.
If your balance or body position falls apart with fists closed, add fins for the first few sets. Fins add propulsion and lift, which lets you focus purely on the forearm and elbow feel before removing that crutch and doing the drill unassisted. Beginners in particular benefit from this progression: fist drill with fins first, then fist drill without fins, then straight into open-hand freestyle.
Why the Fist Drill Works
Your hand normally does a lot of the ‘feel good’ work in freestyle, even when your technique is flawed, because an open palm still catches some water no matter what your elbow is doing. Closing your hand removes that crutch. With a smaller paddle, the rest of your arm — mainly the forearm — has to do the pulling, so any weakness in your catch becomes obvious immediately rather than staying hidden.
This is also why the drill tends to increase stroke tempo: with less surface area per stroke, swimmers naturally speed up their arm turnover to keep momentum, which can help swimmers with an overly long, loping stroke tighten things up.
Fist Drill for Backstroke, Breaststroke, and Butterfly
The fist drill isn’t freestyle-only — the same forearm-awareness principle applies to all four competitive strokes, and it’s worth practicing on whichever stroke you’re trying to refine.
For backstroke, enter the water pinkie-first with the fist and avoid leading with the elbow; rotate the elbow toward the pool bottom to find the vertical forearm position, the same way you would in freestyle. Because backstroke relies more on body balance, fins are especially useful here if you find yourself sinking or losing rhythm with fists closed.
For breaststroke, rotate the elbows outward so the forearms turn vertical, and experiment with how wide you scull out before catching — breaststroke pullers often need a slightly different hand-and-elbow width than freestyle to keep the catch effective with a closed fist. For butterfly, focus on rotating the elbows and pressing upward with a bent-elbow catch rather than pushing straight down; fins help maintain the body undulation and hip drive that butterfly depends on while your hands are occupied learning the forearm feel.
Tips and Common Mistakes
Keep your fist relaxed, not clenched tight — a white-knuckle grip tenses the whole arm and defeats the purpose of feeling for a smooth catch.
If you find yourself flailing or spinning your arms rapidly just to move forward, slow down; that’s usually a sign you’re trying to replace the missing hand surface with speed instead of better forearm positioning.
Watch for wrist breakage — letting the wrist bend backward or forward instead of staying firm in line with the forearm — since this is one of the most common errors in the drill and quietly re-hides the exact flaw you’re trying to fix.
Use feedback whenever you can: swim next to a lane-line mirror if your pool has one, or have a training partner record you underwater. It’s hard to feel your own elbow position accurately, and a few seconds of video is often more useful than repeating the drill blindly for a whole set.
Don’t skip the open-hand comparison length. The drill only helps your real stroke if you immediately swim open-handed afterward and consciously try to replicate the forearm feel — fist swimming alone, without that transfer step, is just an isolated drill that doesn’t change your normal stroke.

fist drill swimming FAQs
What is the fist drill in swimming?
It’s a freestyle (and multi-stroke) drill where you swim with your hands closed into loose fists instead of open palms. With less hand surface area to catch water, your forearm has to do the work instead, which builds the early vertical forearm position and high-elbow catch that make a stroke efficient.
How far should I swim with the fist drill?
There’s no fixed rule, but a common approach is 25 to 50 yards/meters of fists followed by an equal distance of open-hand freestyle, repeated for 4 to 8 rounds within a set. Some swimmers instead drop a single fist-drill 25 into the middle of a longer 100 or 200 swim.
Is the fist drill only for freestyle?
No. It’s most commonly used for freestyle but works for backstroke, breaststroke, and butterfly too, since the goal — using your forearm rather than just your hand to catch water — applies to all four strokes, with small adjustments to elbow rotation and width for each.
Should I clench my fist tightly?
No, keep it loose and relaxed. A tight fist tenses your forearm and wrist and makes it harder to feel the water, which works against the point of the drill.
Can beginners do the fist drill?
Yes, though beginners may want to start with shorter distances and pair the drill with fins or a kickboard to isolate the arm feel without also managing body balance and breathing, then remove the fins once the forearm position feels natural.
What’s the biggest sign the drill is working?
You should notice your elbow staying higher and your forearm feeling more ‘grabby’ in the water once you switch back to open hands, rather than your hand simply slipping through.
