The 9 Best Water Barbells
Updated by · How we research
Pool dumbbells, graded rehab weights and long bar floats compared for water workouts. The Trademark Innovations Aquatic Dumbbells suit most beginners best. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.
A water barbell weighs only a few ounces on land. In the pool, the foam fights you: pushing it under takes real force, and water drags harder the faster you move, so one pair can feel easy or tough. Bigger foam ends mean more work. These suit water aerobics, rehab after injury and joint-friendly toning in chest-deep water.

Editor's Notes
October 23, 2026, by Ezvid Wiki Editors:
The Trademark Innovations Aquatic Dumbbells now lead this list. They're a plain, low-cost pair that fitness roundups keep coming back to, and they suit most people starting pool workouts. The old top pick, the AquaLogix Blue Max, is gone, and so are the PectoFino Water Weight and the Trademark Innovations Triangular. The Kiefer Water Workout has left the store we link to, though Kiefer still sells its own water dumbbells, so it moves to Special Honors. We also cut the Aquastrength Ultimate Bundle, a pricey kit with fins, and the Water Gear Bar Float, which closely matches the new Kemp USA Aquatic Bar Float.
The TheraBand Water Weights replace the old TheraBand Hand Bars listing, and the Speedo Aqua Fitness Barbell, TheraBand Swim Bar and Power Systems Water Dumbbells stay. New picks add a firmer grip, an adjustable set, a long bar float and a shaped grip for sore hands.
No lab has tested foam pool weights. What decided the order was TheraBand's force-to-sink rating for each color, the BarBend and BestReviews roundups, and the wear complaints that keep repeating, mainly glued ends working loose and handles holding water.
Earlier notes

Exercising in the water is great for anyone who needs a low-impact method of working out. It is easier on the joints that using standard dumbbells or barbells on land, and many simply find being in the water to be a more enjoyable way to meet their fitness needs. One of the first things we decided to do during this update was increase the versatility in the offerings. We immediately noticed that the Bintiva Aqua and Trademark Innovations Aquatic were essentially the same as the Speedo Aqua Fitness, so we didn't see how including all three added any value to our readers. The TheraBand Hand Bars also have a very similar design, however these are available in three resistance levels, which can be quickly identified by their color, making them great for use in commercial gyms.
We also chose to remove the TYR Dumbbells. Though the ends of these have an unusual shape that allows you to alter the resistance by how you hold them, the Trademark Innovations Triangular also offer this same ability and we felt that removing one of these would free up space for more variety in the options for our readers. For example, the elimination of the three mentioned models allowed us to add the Aquastrength Ultimate Bundle, which is unlike any of the other selections. It includes paddle-like pieces that you can strap to your legs, as well as pieces that you can either hold in your hands or attach to the included bar to create a dumbbell, making it one of the most versatile options and the best for those that want to activate a lot of muscles at the same time.
The PectoFino Water Weight was also added during this update. It combines floats with paddles, so it can be used to create resistance in every direction. The Kiefer Water Workout and AquaLogix Blue Max are also capable of producing resistance in every direction, so if you want to be able to do curls and other exercises that require you to pull upwards, you'll want to choose either one of these three models or the Aquastrength Ultimate Bundle. Foam dumbbells and barbells, like the Water Gear Bar Float and Power Systems EVA, for example, are great because they are soft and shouldn't cause any harm if you accidentally hit somebody with them, but since they rely solely on buoyancy for resistance, they aren't of any help when performing exercises where you need to pull upwards.

Because water dumbbells and barbells keep the pressure off your joints while still forcing you to condition your muscles thanks to underwater drag, they're great for all fitness levels, whether you're elderly, recovering from injury, or a serious athlete. While the general design is similar from model to model, things like weight, shape, and size can greatly affect your training. Combining them with items like buoyancy belts and aquatic gloves can help take physical therapy and aerobic exercises to the next level.
We wanted to ensure this list had a diverse assortment to cater to the myriad needs users might have, from lightweight options good for beginners to professional units that can provide a high-intensity workout.
To that end, you'll find the TYR Dumbbells and Trademark Innovations Triangular are both excellent for those who want to add resistance to their workout but not strain themselves too much. Arthritic users will appreciate the TheraBand Pool Training for their oversized padded handles, while the Speedo Aqua Fitness are great for those who want something more challenging.
We removed the Power Systems Dumbbells due to persistent quality complaints, as well as the Aqua Sphere Ergobells because of availability concerns. The vacancy left by the Aqua Sphere models gave us a chance to add the AquaLogix Blue Max. This professional-grade set is crafted in San Diego, California, and is meant for high-intensity training. Their resistance can be controlled to cater to a variety of regimens, but they're likely too much for beginners.
Special Honors
Kiefer Water Fitness Gear Kiefer, a long-running swim and pool supply company, still sells its own water dumbbells on its site, including Deluxe Fitness Bells in five resistance levels from minimum to maximum, foam dumbbell pairs in mini, medium and large sizes, and Signature swim bars in two lengths. It's a handy source for building a graded set or matching what a local pool already uses. kiefer.com
Where The Resistance Comes From
Power Systems sells the same handle with one, two or three floats per end for light, medium and heavy work.
Foam pool weights work against two forces. Buoyancy pushes the foam up, so pressing it under the surface takes effort, and letting it rise slowly works the same muscles on the way back. Drag resists any movement through water, and it grows the faster you move. Physical therapists at Brown Health point out that water resists rapid movement far more than air, which is why fast moves feel hard even with light gear (Brown Health).
That makes size the main dial. Bigger foam ends, or more rings per end, sink harder and catch more water. TheraBand rates its three colors by the force needed to push one under: about 2.5 pounds for red, 4 for green and 6 for blue. Power Systems sells the same handle with one, two or three floats per end for light, medium and heavy work. Speed is the second dial, so a light pair still challenges you if you move briskly.
For beginners, BestReviews suggests starting at an easy resistance, since simply keeping the foam submerged through each move is enough for a good workout (BestReviews). Move up a level when a full set of 15 reps feels easy.
Pairs, Bars And Adjustable Sets
Most people want a pair of foam dumbbells, one in each hand, for curls, presses, flys and push-downs. Fixed pairs such as the Trademark Innovations Aquatic Dumbbells or the Speedo Aqua Fitness Barbell are ready out of the box. Graded lines let you step up a level: TheraBand by color, Power Systems by float count. Adjustable sets such as the Hikeen Aquatic Dumbbells let you add or remove foam plates on one handle, which helps when two people of different strength share a set.
A long bar float is a different tool. You hold a single bar such as the TheraBand Swim Bar or the Kemp USA Aquatic Bar Float with both hands for core twists, balance work, supported kicking and leg moves with the forearms resting on it. Pool suppliers such as Kiefer sell swim bars in 26- and 30-inch lengths alongside hand-held bells in five resistance levels.
Grip matters more than it seems over a long class. Padded or foam-covered handles are kinder to the hands, a stiff core keeps the handle from flexing, and shaped grips help stiff fingers. Watch for the two common wear points: BestReviews flags handles that fill with water and drain slowly, and BarBend notes that glued foam can let go after long use.
Safety, Depth And Care
Foam weights are exercise gear, not flotation devices. Trademark Innovations rates its pair for ages 14 and up and warns against using it as a float, and Kemp labels its bar a training aid rather than a life-saving device. Work in water where you can stand, usually waist to chest deep, and keep a close eye on children and weak swimmers.
Water takes much of the load off joints, which is why it's a common setting for arthritis exercise and physiotherapy. Arthritis Action suggests talking to a doctor or physiotherapist first if you're unsure whether water exercise suits you (Arthritis Action). That goes double for anyone with a heart condition, a recent operation, a pregnancy or an active rehab plan.
Care is simple. Rinse the foam in fresh water after chlorine or salt water, shake water out of the handles, and dry the weights out of direct sun, which fades and stiffens foam over time. Check glued joints now and then, because a loose end can slip off mid-move.
How we researched this
We compared 18 water barbells, foam dumbbells and bar floats, read makers' specs and TheraBand's published resistance ratings, the BarBend and BestReviews roundups, and aquatic therapy guidance from Brown Health and Arthritis Action, looked for patterns in owner feedback, and checked the brands against the U.S. Consumer Product Safety Commission's recall database.
Frequently asked questions
How heavy are water barbells?
Out of the water, a pair weighs a few ounces to about a pound. The work comes from pushing the foam under and moving it through water. TheraBand rates its red, green and blue weights by the force needed to sink one: about 2.5, 4 and 6 pounds.
Are water barbells good for seniors and rehab?
Yes, for many people. Water takes weight off the joints, and you control the resistance with your speed. Start light, such as the red TheraBand Water Weights, and check with a doctor or physical therapist first if you have a heart condition, a recent surgery or an injury.
Can I use water barbells as a float?
No. They are exercise gear, not flotation devices, and makers such as Trademark Innovations and Kemp say so. Use them where you can stand, and supervise children and weak swimmers.
How deep should the water be?
Waist to chest deep works best for most moves. You need to stand firmly while pushing the foam under the surface.
Should I get fixed or adjustable water weights?
A fixed pair is simplest. If you expect to get stronger or share a set, an adjustable pair like the Hikeen Aquatic Dumbbells or a graded line like TheraBand or Power Systems lets you step up without starting over.
Can I use them in the ocean or a lake?
Yes. The EVA foam handles chlorine and salt water. Rinse it in fresh water afterward and dry it out of direct sun.
