Water Weights for Aqua Fitness Classes

A refillable water-filled weight that works like a kettlebell or dumbbell. Fill it with tap water to the weight you want, and empty it when you're done.

Each weight adjusts from 1 to 11 lb (0.5–5 kg), and a set of 2 gives you up to 22 lb combined. Empty, each weighs just 0.8 lb (about 360 g).

Each weight measures 12.3 in long, 4.7 in wide and 13.7 in tall (31.2 × 12 × 34.7 cm), or roughly 12.5 × 5 × 14 in. It's slim enough for a closet shelf or a backpack.

Fill lines in both lb and kg are molded into the jug, so they won't wear off. Each line shows the total weight, including the 0.8 lb jug, and the slightly translucent body lets you see the water level as you fill.

No. The plug-seal cap locks watertight and the plastic is thick and durable. Reviewers consistently report zero leaks.

Very. It's made from high-density polyethylene (HDPE), the same kind of tough plastic used for toolboxes and motor-oil bottles, chosen for its impact strength and resistance to cracking. It also stays tough in the cold rather than turning brittle. Just empty it before leaving it somewhere below freezing, since water expands as it freezes.

The top handle and two side handles give you multiple grip options. Hold it one-handed like a kettlebell, or grip both sides for crunches, squats and Pilates. That means more exercises than a single-grip weight allows.

Each handle is 1 in (2.5 cm) in diameter, about the same as a standard dumbbell handle. The smooth plastic is easy to wrap your fingers around, with no knurled metal to rub your palms.

Yes, it's BPA-free. It's made from HDPE (high-density polyethylene), the same type of plastic used for milk jugs, which isn't made with BPA. The resin meets FDA requirements for plastics that come into contact with food (21 CFR 177.1520), confirmed by the manufacturer and by independent lab testing.

AguaForce comes with a 30-day money-back guarantee. If it breaks within 30 days, you get your money back.

Empty it after each workout and let it air-dry with the lid off before storing. Wipe the handles with a damp cloth as needed, and between users if you share weights in a class. Refill with fresh tap water each session.

Aquatic instructors report that the handles are easy to grasp for both younger and older users, including people with arthritic hands. Holding it with both hands on the side handles spreads the load and gives you more control.

Yes. Online orders come in sets of 2, but wholesale orders can be any quantity, so you can equip a whole class. Request a price on the AguaForce website.

Empty, each one weighs under 1 lb, so you can carry a class set in a bag instead of hauling cast iron. Fill them on-site from a tap or water jug and pour them out when class ends.

Yes. Aquatic instructors use it in both shallow-water and deep-water aqua aerobics classes.

Instructors follow a simple rule of thumb. When the weight stays mostly underwater, use it empty, because the water itself provides the resistance. When the weight comes mostly out of the water (for example, lateral raises), fill it.

Empty and sealed, it's full of air, so pushing it below the surface works against buoyancy, and moving it through the water adds drag. It's the same principle as foam aqua dumbbells, with the bonus that you can fill it for moves done above the water.

Foam aquatic dumbbells only give resistance in the water: they float, so pushing them under works your muscles, but on land they weigh almost nothing. AguaForce does both. Use it empty underwater, where buoyancy and drag provide the resistance, or fill it with water for moves above the water and for workouts on land.

Yes. Adding some water reduces how strongly it floats, so each participant can dial in a level that suits them. One piece of equipment can serve the whole class, from first-timers to strong swimmers.

No. It won't damage the pool floor if dropped, and it holds its shape underwater.

The three handles allow a wider range of in-pool exercises, and the adjustable water level lets each participant set their own resistance. In the instructors' words, their users "really like" them.

No. It's made from HDPE, a plastic known for its chemical resistance, so chlorine and salt water won't affect it. After class, just empty it and let it air-dry before storing.
