A pull buoy is held between the legs to support the lower body while you focus on the arm stroke; hand paddles enlarge the hand's surface against the water and add resistance and feedback. They solve different training problems, so choose by the set's goal rather than buying both by default. U.S. Masters Swimming advises new paddle users to start small because larger paddles increase shoulder strain.
Pull buoys and hand paddles are often sold near each other, but they change different parts of a swim. A buoy supports the legs; paddles change the hand’s contact area and resistance. Choose the tool that matches the set you want to do.
Compare the training purpose
| Tool | What it changes | Useful for | What to check |
|---|---|---|---|
| Pull buoy | Supports the legs when held between the thighs | Focusing a set on the arm stroke or feeling a more supported body position | Shape, size and whether it stays comfortably in place without being squeezed hard |
| Hand paddles | Increase the hand’s surface area and resistance against the water | Feedback on the catch and pull, or a planned resistance set | Hand coverage, shape, size and strap adjustment |
A pull buoy does not replace instruction in a safe kick or body position, and it is not an open-water safety float. Hand paddles do not automatically improve technique: they magnify the pressure in a stroke, so size and fit matter.
Start with the paddle size and fit
U.S. Masters Swimming explains that paddles can provide feedback on movement, but they also increase shoulder strain. Its guide to buying and using paddles advises newer swimmers to start small, consider their stroke and get input from a coach when available. It also cautions against over-tightening straps; straps should not be doing all the work of keeping the paddle on your hand.
If the paddle shifts or you feel pain, stop and adjust the size, setup or technique with a knowledgeable coach. Do not choose a larger paddle because a faster swimmer uses one. A smaller or fingertip-style paddle can be an easier starting point, but the right choice depends on the swimmer and the session.
Choose a buoy by fit and use
Pull buoys are made in different shapes and sizes. The key decision is whether the buoy sits between your legs securely enough for the drill without forcing an uncomfortable squeeze. Follow the product’s instructions and your coach’s guidance. U.S. Masters Swimming describes a pull buoy as a block held between the thighs to support the legs while a swimmer works on other parts of the stroke.
For other tools that alter propulsion and kick tempo, compare short- and long-blade swim fins. Fins add propulsion at the feet; buoys support the legs and paddles change hand resistance, so they are not direct substitutes.

Common questions
What does a pull buoy train?
A pull buoy supports the legs between the thighs so you can focus on the arm stroke without relying on a kick for the same forward movement. It is a training aid, not a flotation device for open-water safety.
What do hand paddles do?
They increase the surface area of the hand against the water, adding resistance and feedback during the catch and pull. Paddle shape and size change how they feel.
Should beginners use large swim paddles?
U.S. Masters Swimming recommends starting small because larger paddles increase pressure on the water and strain on the shoulders. Ask a knowledgeable coach about size and technique.
Can I use a pull buoy and paddles in the same set?
They change different aspects of a swim. If your written workout combines them, follow its instructions; when both are new to you, start with one at a time so you can assess fit and technique.
