What Is a Pull Buoy and What Does It Do?
A pull buoy is a figure-of-eight foam tool designed to fit between your legs during swims. Imagine the figure-of-eight shape like two connected ovals, one slightly larger than the other, made of soft, buoyant foam that floats easily. You place it between your upper thighs (just below the crotch) or near the ankles, with the larger end facing down toward the pool bottom for maximum lift on your hips. This positioning traps air and provides buoyancy to raise your legs and hips, creating a more streamlined, horizontal body position where your body glides closer to the water’s surface like a straight arrow.
What does it do? The pull buoy lifts your hips and legs, reducing drag caused by a sinking lower body and removes leg propulsion—so your kick doesn’t drive you forward. This shifts all forward movement to your arms and shoulders, giving an upper body focus that highlights your stroke technique.
Swimmers and triathletes commonly use it to build awareness of body alignment or when practicing without leg power. For example, triathletes with tired legs from biking or running can rely on their arms to maintain momentum during pool sessions.
Choosing the right size matters for comfort and effectiveness. Here’s a quick guide to match your needs:
| Age/Level | Recommended Size | Purpose |
|---|---|---|
| Under 16 | Three stripe pull buoy (smallest size option) | Alignment focus without overwhelming buoyancy |
| Adult beginners | Standard | Balanced lift for body alignment and upper body focus |
| Senior swimmers | Standard or slightly larger | Alignment support with easy grip for power development |
Next, we’ll explore the key benefits of using a pull buoy to see how it supports your progress.
Key Benefits of Using a Pull Buoy
Using a pull buoy offers targeted benefits for beginners by shifting focus to the upper body while supporting the legs. These advantages help build specific skills when used for particular goals like technique refinement.
Upper Body Strength and Endurance
A pull buoy removes leg propulsion, so your arms and shoulders must do all the work to move forward. This upper body focus builds strength and endurance in the pulling muscles over time. Beginners often notice their arms tiring faster at first, which highlights areas for improvement.
Better Focus on Stroke Technique
Without kicking, you can concentrate on stroke technique, including the catch (where your hand enters the water and grabs hold), pull phase (sweeping backward through the water), and recovery phase (arm exiting forward above the water). For more on improving these in freestyle, check our freestyle stroke tips. This isolation helps beginners refine arm paths without distractions from the legs.
Core Stability and Alignment
The pull buoy lifts your hips and legs, promoting a streamlined, horizontal body position. Even with this support, keep your core engaged to stay stable and prevent twisting or sagging. This teaches core strength as you maintain alignment during the swim.
Breathing Practice
Added buoyancy keeps your body higher in the water, making it easier to turn your head for breaths without your legs sinking. Beginners can practice steady breathing rhythms while focusing on upper body movements.
Support for Tired Legs
Triathletes with tired legs after a hard run or bike session find pull buoys useful. After intense cycling, a swimmer can insert the buoy to continue quality sets without leg drag pulling them down, targeting upper body work instead.
While these benefits support specific training, pull buoys have limitations too. The table below outlines pros and cons based on technique outcomes.
| Pros | Cons |
|---|---|
| Enhances upper body isolation for strength building | Risk of over-reliance, weakening natural leg propulsion |
| Improves body alignment awareness | Can cause hips too high if not balanced with core engagement |
| Allows focused stroke technique practice | May disrupt full-body coordination if used excessively |
| Supports breathing and tired-leg scenarios | Potential for imbalance without mixing in full swims |
Next, we’ll cover how to use a pull buoy step-by-step for beginners.
How to Use a Pull Buoy: Step-by-Step for Beginners
Using a pull buoy correctly helps beginners achieve better body alignment and upper body focus. Follow these steps to select, insert, and swim with one effectively, keeping in mind the goal of improving stroke technique intentionally.
Choosing the Right Size
Start by picking the correct size for your age and level to ensure a secure fit and proper lift for your hips and legs. Beginners and those under 16 should opt for the smallest option, like a three stripe pull buoy, to avoid excess buoyancy that lifts the legs too high and disrupts streamlined, horizontal body position. For guidance on the best pull buoys for beginners, consider your body size and swimming experience. An oversized buoy can cause hips to rise excessively, making balance harder and reducing the training effect on core engagement.
Placement Options: Thighs vs. Ankles
You can place the pull buoy between the thighs (just above the knees) for more stability and lift, which supports beginners in maintaining a long, horizontal body line with less effort on core stability. Placing it near the ankles demands stronger core engagement for balance and rotation but allows a longer lever for advanced body position work. (Ankle placement is recommended only for more experienced swimmers, not beginners.) Thigh placement is ideal for most beginners as it promotes easier body alignment without bending at the hips.
No kicking is the default rule—your legs provide no propulsion, shifting all work to the upper body. Slight foot movements for balance are okay if minimal and not propulsive, but hard kicking makes the buoy slip and wastes energy.
Focus on body position cues: keep hips level (not excessively high), extend your body into a streamlined, horizontal line, and engage your core gently by squeezing the buoy lightly with your inner thighs. This connects your upper body to a stable core for better stroke rhythm.
Watch for common mistakes right away, like hips rising too high (sinking when the buoy is removed), over-reliance on hard pulling without rotation (leading to shoulder strain), or kicking too hard (buoy slips, poor upper body focus).
Step-by-Step Checklist for Using a Pull Buoy
- Choose the right size based on your age and level, such as the three stripe pull buoy for under 16 or beginners.
- Wet the pull buoy slightly and hold it in one hand while treading water or standing in shallow water.
- Insert it securely between your thighs (or near ankles for more challenge), squeezing gently to lock it in place with the larger end under your body for maximum buoyancy.
- Push off the wall into a streamlined position, arms extended forward, body long and horizontal.
- Set a smooth stroke rhythm with no kicking, focusing on even breathing and core engagement.
- Check your hips (level, not high) and core (gently squeezed) every few strokes for consistent body alignment.
- Finish the set strong, then remove the buoy to feel how your stroke transfers without it.
Signs of Proper Pull Buoy Use
Use this quick checklist to self-assess during your swim and confirm you’re getting the benefits.
- Hips level, not excessively high, for natural streamlined flow.
- Core engaged through a light squeeze on the buoy.
- No kicking—legs float without propulsion.
- Smooth stroke with steady rhythm and rotation.
- Balanced propulsion from arms and body alignment.
Pull Buoy Drills for Freestyle Swimming
Pull buoy drills for freestyle give beginners a focused way to build upper body strength through structured practice. These drills emphasize stroke technique without leg propulsion, helping you refine arm movements and breathing in a controlled setting.
Start with a slow stroke focus drill to build awareness. Swim freestyle at a relaxed pace with the pull buoy between your thighs, counting each stroke deliberately to one or three. Focus on arm entry: fingers first into the water shoulder-width apart, then a smooth catch where your forearm presses backward. Time your breathing to the side on every third stroke for rhythm. A common error is rushing the entry, which creates splash; avoid this by entering pinky-first and gliding your hand forward before catching.
For technique sets, try 4×50 smooth strokes. On each 50, maintain a steady stroke count, prioritizing relaxed recovery where your arm exits thumb-first and swings forward loosely over the water. Breathe consistently to one side, keeping your head aligned with your spine. Rest 20 seconds between repeats to reset. This builds consistent breathing and arm entry without fatigue. Watch for the mistake of pausing too long at the catch, which slows propulsion; keep the pull phase continuous.
Strength and endurance examples ramp up the challenge. Use 4×100 for controlled effort, focusing on steady form through the full stroke cycle. Build to a 500 steady pull set at a comfortable pace, holding your streamlined, horizontal body position with core engaged. Triathletes can adapt these when legs are tired, using the buoy to maintain upper body focus without straining fatigued muscles.
Include variation with minimal kick for balance only if you feel wobbly, like a light flutter, but default to no kicking to isolate upper body work. For more structured sessions, check out more swim workouts.
The table below outlines a sample workout with execution cues.
| Set/Drill Name | Distance/Rep Scheme | Main Focus Cue | Notes/Common Errors to Avoid |
|---|---|---|---|
| Slow Stroke Focus | 4×50 | Arm entry and breathing timing | Count strokes to 1-3 per side; avoid rushing entry which splashes |
| Smooth Strokes Technique | 4×50 | Relaxed recovery, consistent breathing | Rest 20s; avoid pausing at catch to maintain propulsion |
| Strength Pull | 4×100 | Steady form through stroke cycle | Controlled effort; avoid dropping hips by engaging core |
| Endurance Pace | 500 | Streamlined position, even pacing | Minimal kick if needed for balance; avoid over-breathing which disrupts rhythm |
Pull Buoy vs Kickboard: Which to Choose?
Understanding the differences between these two training aids helps beginners pick the right tool for their goals. Pull buoys provide buoyancy that lifts the hips and legs, allowing a streamlined body position while removing leg propulsion. Kickboards support the upper body at the arms or chest, forcing swimmers to rely on leg kicks for propulsion.
A pull buoy isolates the upper body by lifting your hips into a streamlined, horizontal position. In contrast, a kickboard supports your arms, requiring your kick to drive motion forward. Choose based on what needs improvement: use a pull buoy when working on upper body focus, stroke technique, or alignment without leg fatigue. Opt for a kickboard when building leg strength, kick power, or endurance in the lower body. Neither tool is superior overall; they complement each other as different tools for different goals.
The table below highlights key differences to guide your choice.
| Aspect | Pull Buoy | Kickboard |
|---|---|---|
| Primary focus | Upper body isolation and arm propulsion | Leg kick development and lower body power |
| Body position effect | Lifts hips/legs for streamlined, horizontal alignment | Requires core effort to maintain alignment; hips may drop without strong kick |
| Best for | Stroke technique, core engagement, tired legs | Building kick strength, leg endurance, balance |
| Common pitfalls | Over-reliance leads to weak kick; hips too high if not balanced | Arm fatigue or poor head position; encourages sinking hips |
| When to avoid/limit | Avoid if kick needs primary work; limit to 25% of session | Avoid if upper body technique is poor; limit to 25% of session to preserve arm technique development |
For kick-focused practice, explore kickboard drills to build that leg propulsion effectively.
Common Mistakes and How to Fix Them
Even well-intentioned swimmers can fall into habits that reduce the effectiveness of the pull buoy or create imbalances in their stroke. Understanding these mistakes and how to correct them will help you get the most from your training without developing bad habits.
Kicking Too Hard or Letting the Buoy Slip
Many beginners instinctively kick when they feel the buoy moving or their body sinking slightly. This defeats the entire purpose of the training aid. When you kick, you’re adding leg propulsion back into the equation, which means your upper body isn’t truly isolated and the buoy isn’t doing its job of supporting your hips.
Why this happens: Swimmers are conditioned to kick as part of normal swimming, so removing the kick feels unnatural. When balance feels shaky, the instinct is to move the legs to regain control. For example, when your buoy shifts and you feel your hips drop slightly, your instinct is to flutter-kick to pop back up—but this defeats the whole point of the buoy.
What it causes: Your kick can cause the buoy to shift position or slip out from between your thighs. More importantly, you miss the chance to develop true upper-body strength and body awareness because you’re splitting focus between arms and legs.
The fix: Keep your legs still and straight throughout the set. Your feet can make small, gentle movements if needed only to maintain balance, but these should be minimal. If the buoy keeps slipping, it may be positioned too low (see sizing and placement guidance). If balance is the problem, try shorter repeats with more rest so you can focus on quality rather than fighting to stay afloat.
Hips Too High or Dropped Too Low
A pull buoy lifts your hips, but too much lift can actually distort your body alignment. Conversely, if your core isn’t engaged, your hips can sag despite the buoy, creating a V-shaped body position instead of a streamlined horizontal line.
Why this happens: Oversized buoys or buoys placed too high on the legs create excessive lift. Poor core engagement also allows the hips to sink. Some swimmers also lean their head forward, which pulls the hips down in compensation.
What it causes: Exaggerated hip position teaches your body the wrong alignment. High hips can force you to enter your hands too far forward. Sagging hips increase drag and place excess strain on your shoulders. When you remove the buoy, your body position reverts to its default—often worse than before, because you’ve practiced the wrong alignment.
The fix: Gently engage your core (imagine a light squeeze around your midsection) to keep your hips level with your shoulders. Your body should form one long, straight line from your head to your heels. Keep your head in a neutral position—your eyes should look slightly forward and down, not up. If your hips are too high, try a smaller buoy or position it lower on your thighs. If they’re dropping, focus on that gentle core squeeze and take shorter rest intervals so you reset with good form.
Overusing the Buoy and Losing Kick Development
Pull buoys are training tools, not permanent equipment. Using them for too large a portion of your sessions can lead to reduced leg strength and kick efficiency. You may also find that when you remove the buoy, your full stroke feels foreign because you’ve spent most of your time with an unnatural body position.
Why this happens: Pull buoys feel good—they provide instant feedback and often make you feel faster because your hips are higher. It’s tempting to use them for most of your workout, especially if you struggle with body position or want to focus on arm strength.
What it causes: Your kick becomes weaker over time because you’re not training it consistently. Your full-stroke swimming may actually worsen because the alignment you practice with the buoy (very high hips, upper-body-only propulsion) doesn’t match the alignment you need for balanced, whole-body freestyle. You may also develop shoulder fatigue or imbalance if arms are overworked.
The fix: Use the pull buoy for no more than 25% of your total swimming time per session. For example, in a 2000-meter workout, spend roughly 500 meters with the buoy and 1500 without it. This keeps your kick sharp and ensures your full-stroke technique stays primary. Balance pull buoy sets with regular freestyle, kick sets, and drills that use both upper and lower body.
Wrong Size or Poor Fit for Your Age or Level
Pull buoys come in different sizes. An oversized buoy can create a false sense of body position—it lifts you too high and doesn’t require the same core control as a properly fitted tool. For swimmers under 16, using an adult-sized buoy can be especially problematic because their smaller frames don’t get the right support.
Why this happens: Many swimmers grab whatever buoy is available at the pool without checking sizing. Parents or coaches may not realize that junior sizes exist.
What it causes: An oversized buoy teaches poor habits because you’re not learning the actual body position required for good freestyle. You may feel faster temporarily, but your alignment is artificially supported and won’t transfer to swimming without the aid. A buoy that’s too small won’t provide enough support and may feel unstable.
The fix: Choose a buoy matched to your size and experience level. For swimmers under 16, look for a junior or small-sized option such as a three stripe pull buoy (the smallest size option for young swimmers). If you’re an adult beginner, a standard adult pull buoy is appropriate. If you’re unsure, ask your coach or try the tool in the pool before committing to a set; it should feel stable and supportive without feeling like a raft. Always place the larger, rounded end underneath your body to maximize buoyancy.
Beginner Mistakes Checklist
Use this quick checklist to catch yourself before these habits take hold:
- Are you kicking hard or letting the buoy slip? Keep your legs still.
- Are your hips too high or drooping? Engage your core gently and check your head position.
- Is the buoy more than 25% of your session? If so, add more full-stroke swimming.
- Is your buoy the right size for your age and frame? Confirm sizing before extended use.
- Does your full-stroke feel strange after pull buoy work? You may be overusing the aid.
Remember that the pull buoy is a teaching tool, not a replacement for balanced, full-stroke training. When used correctly, it reveals technical gaps and builds upper-body strength. When misused, it can entrench poor habits and create imbalances. If you notice any of these mistakes, pause the set, reset your position, and refocus on quality. A few perfect repeats with good alignment beats many sloppy repeats with a bad position. For additional guidance on how to strengthen your core and support these corrections, explore core exercises for swimmers that complement your in-water work.
Tips for Beginners and When to Use Moderately
The pull buoy is most effective when paired with smart guidelines. These tips help you use it across different groups, from young swimmers to senior swimmers and triathletes, while keeping your overall stroke technique balanced.
Guidance for Swimmers Under 16
For swimmers under 16, always choose the smallest size option like the three stripe pull buoy to avoid excess buoyancy that could disrupt body alignment. Prioritize developing a proper kick first, as leg propulsion builds foundational skills; use the pull buoy only occasionally to supplement, not replace, kicking practice.
The 25% Session Moderation Rule
Limit training aids like the pull buoy to no more than 25% of a session to ensure your skills transfer to full-stroke swimming. For example, in a 2000-meter workout, dedicate no more than 500 meters to pull buoy sets, leaving the rest for regular freestyle and other normal swimming to maintain balanced propulsion and technique.
Combine pull buoy work with full freestyle regularly so improvements in upper body focus and core engagement carry over without creating reliance.
Audience-Specific Nuance
Senior swimmers often benefit from pull buoy use for better body alignment and upper-body power without heavy leg demands. Triathletes with tired legs can use it to maintain streamlined, horizontal body position during sessions focused on triathlon swim prep, but still follow the 25% rule to preserve overall endurance.
Choose Pull Buoy If… Decision Tree
Use this simple if/then guide to decide when the tool fits your goals:
- If you have tired legs from biking or running, choose the buoy to lift hips and focus on upper body without leg propulsion.
- If you want to refine technique like breathing or arm entry, choose it for distraction-free practice on stroke rhythm.
- If alignment feels off and core stability is a challenge, choose it to feel a streamlined, horizontal body position.
- Otherwise, stick to full-stroke swimming to build complete skills.
In-Water Core Engagement Tips While Pulling
While using the pull buoy, try these easy technique-focused tips to boost core engagement:
- Gently squeeze the pull buoy with your inner thighs on each stroke to connect legs to core and maintain a taut body line.
- Exhale steadily underwater, then rotate smoothly during breathing to engage core muscles and prevent hinging at the hips.

FAQ: Pull Buoy Swimming Basics
What is a pull buoy?
A pull buoy is a figure-of-eight foam tool placed between the thighs to provide buoyancy for your hips and legs. It removes leg propulsion to create upper body focus, helping with alignment by lifting your lower body into a more streamlined, horizontal line.
When should beginners use a pull buoy?
Beginners should use it during technique-focused sets—like drills for breathing or arm entry—or when working on upper body focus, such as after tiring leg workouts. Limit it to no more than 25% of your session to avoid over-reliance, and pair it with full-stroke swimming for balanced practice.
Can pull buoy hurt your technique?
Yes, it can disrupt stroke technique if misused, like placing it too low or squeezing too hard, which raises hips too high and creates poor alignment. Focus on gentle core engagement and no kicking to maintain smooth, balanced propulsion instead.
How to avoid overusing pull buoy?
Avoid overuse by sticking to no more than 25% of your swim session, such as 500 meters of pulling in a 2000-meter workout. Alternate with kicking or full-stroke swims to build overall skills and prevent upper-body imbalance from too much isolated work.
Pull buoy for different ages?
For under 16 swimmers, choose the smallest size like a three stripe pull buoy to avoid overwhelming buoyancy that could harm alignment. Senior swimmers benefit from it for alignment support, but all ages should prioritize proper sizing and moderation to support overall development.
Best for beginners?
A pull buoy is helpful for beginners focusing on upper body strength and proper alignment, especially if sinking legs make swimming feel unbalanced. Use it briefly in drills to feel a streamlined position, but always combine with other training methods for complete stroke development.
Fix sinking legs?
A pull buoy helps you practice better body position and core engagement because it lifts your hips. However, to truly fix sinking legs, you’ll need to build core and kick strength without the aid. Use the buoy as a teaching tool to feel proper alignment, then focus on full-stroke practice to develop the muscles that keep your legs up.
