Learning how to use a pull buoy is simple: you tuck the figure-eight-shaped foam float between your thighs, stop kicking, and swim using only your arms — which lets you isolate your upper body and feel what a high, streamlined position is really like. Here’s how to place it, use it in a set, and avoid the mistakes that make it less useful.

The short answer

A pull buoy is a buoyant foam float you hold between your thighs (or lower, between your knees or ankles) so your legs stop working and float up. With the kick removed, you can focus entirely on your arm pull, breathing, and body position. It’s excellent for building pulling strength, smoothing out your stroke, and — because it lifts your hips — letting you feel the level, gliding shape you’re chasing when you swim normally. One important caveat: it is a training aid, not a flotation or safety device.

What a pull buoy is and where it goes

A pull buoy is a piece of dense foam shaped a bit like a figure eight or an hourglass, sized to wedge comfortably between your legs. There’s no “right” side up — just squeeze it in and go.

  • The standard spot is between your upper thighs. This gives the most lift and the most stable hold, so your hips ride high and you can relax. Start here.
  • Lower placements are a progression. Held between the knees or ankles, the buoy floats less of your body and challenges your core to keep everything aligned. Try this only once the thigh position feels natural.
  • Hold it snugly. If it keeps popping out, squeeze your legs gently together — you shouldn’t have to clamp hard, but a light, steady hold keeps it in place.

What it’s actually for

The whole point of a pull buoy is to take your legs out of the equation so your upper body gets your full attention.

  • It isolates the pull. With no kick to think about, you can feel your hand entering the water, catching it, and pushing it back — the engine of your freestyle. This is why swimmers call these “pull sets.”
  • It improves body position. The buoy lifts your hips into a flat, streamlined line, so you get to experience the position good swimmers hold naturally. If your legs tend to sink, this lets you feel the alternative.
  • It builds feel for the water. Freed from kicking, you can pay attention to the “grip” of your hand and forearm against the water — the subtle skill that makes every stroke count.
  • It builds pulling strength. Moving your whole body with arms alone is honest work, and it strengthens the muscles that drive your stroke.

How to use it in a set

You don’t need anything complicated. Slot pull work into your swim like this:

  1. Warm up normally first, swimming a few relaxed lengths with your usual kick.
  2. Add a pull block — for example, swim a handful of lengths with the buoy in, focusing on one thing at a time: a long reach, a clean catch, or steady breathing.
  3. Alternate buoy lengths with normal lengths so you keep connecting the feel of the pull back to your full stroke.
  4. Finish with easy swimming to cool down.

A useful cue while pulling: think “reach and hold.” Reach forward fully on each stroke, then feel like you’re holding a spot in the water and drawing your body past it. Pair this with the ideas in how to streamline when swimming — the buoy makes that long, tall shape much easier to find.

Common mistakes to avoid

  • Kicking anyway. If your legs keep fluttering, the buoy isn’t isolating anything. Let your legs go quiet and trail behind — that’s the point.
  • Clamping too hard. A death grip creates tension all the way up your body. Hold just firmly enough to keep the buoy in place.
  • Dropping your head to look forward. Keep your head neutral, eyes down, so your hips stay up. Lifting your head sinks the legs even with a buoy in.
  • Using it every single length. The buoy is a tool, not a crutch. Always mix in normal swimming so your kick and your pull learn to work together.
  • Treating it as a float to rest on. It’s for active swimming within your depth — not for bobbing in deep water. Remember, it is not a safety device.

Who it helps

Pull buoys suit almost anyone past the total-beginner stage who can already swim a length or two of freestyle. They’re especially handy if:

  • Your legs sink and you’ve never felt a high body position — the buoy shows you the target.
  • You want a stronger, cleaner pull without your kick masking what your arms are doing.
  • You’re building fitness and want to work your upper body specifically.

If you’re still finding your feet with the stroke itself, spend more time on the basics first — the buoy will make far more sense once your freestyle feels smoother.

A quick safety reminder

Only use a pull buoy within your depth or in a lifeguarded pool, and never swim alone while relying on equipment. Because it removes your kick, you’ll feel a little different in the water — stay relaxed, and if you ever feel unsure, simply drop the buoy and stand up or swim normally.

The next small step

Next time you swim, borrow or bring a pull buoy and do just a few quiet lengths with it between your thighs — no kicking, eyes down, reaching long on every stroke. Notice how high your hips float and how much you can feel your hands gripping the water. Then take it out and try to carry that same tall, connected feeling into your normal swimming.
