Adjustable Weights for Beginners

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).

Open the lid, fill it at any tap to the line for the weight you want, and close the lid firmly so it seals. When you're done, pour the water out. No tools, plates or pins.

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.

Yes. Weight is weight: 5 lb of water loads your muscles exactly like 5 lb of cast iron. The difference is that water moves, which adds a stability challenge metal weights don't have.

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.

Yes, and that's a good thing. As the water shifts, your muscles work to keep the weight steady, which adds core engagement and focus to every move. Customers say it helps them concentrate and control their form. Slow, controlled movements work best.

You can work your whole body: arms, chest, back, abs, glutes and legs. Examples include squats, lunges, weighted crunches, hip thrusts, swings, lateral raises and Pilates. The free interactive exercise library at cards.aguaforce.com shows how to do each one, sorted into upper body, core and lower body sections with the target muscles highlighted.

Every set comes with 2. Use one for kettlebell-style moves like swings, goblet squats and weighted crunches, or both for dumbbell-style moves like curls, presses and lateral raises. You can also set each to a different weight, for example a heavier one for squats and a lighter one for shoulder raises, so you're not refilling between exercises.

For $48.85 CAD in Canada ($39.85 USD elsewhere; promotional prices, regularly $59.48 CAD and $45.54 USD) you get 2 weights that each cover 1–11 lb, far less than buying several kettlebells or dumbbells, and they take up a fraction of the space. AguaForce tops out at 11 lb per weight, so it's designed for toning, strength building and everyday fitness rather than heavy lifting.

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.

No. AguaForce is built for home workouts, including on days when rain or a busy schedule keeps you from the gym.

Within the 1–11 lb range, yes. Instead of buying and storing several fixed weights (2, 3, 5, 8, 10 lb), you simply change the water level.

About the footprint of a yoga mat. Squats, lunges, crunches, Pilates and arm work all fit in a living room, bedroom or balcony.

Absolutely. Start empty or with just 2 lb of water, then add more as you get stronger. There's no intimidating chunk of metal to deal with.

Start lighter than you think. Choose a fill level where you can do 10 to 15 slow, controlled reps with good form and finish feeling challenged but not strained. When that feels easy, add a little water.

Add a little more water. You can increase in small steps instead of jumping from 5 lb straight to 8 lb, which makes steady progress easier.

The CDC recommends muscle-strengthening activity on at least 2 days a week, working all the major muscle groups: legs, hips, back, abdomen, chest, shoulders and arms. Adults 65 and older should add balance activities too. Two or three sessions a week is a good start for most beginners, with a rest day between strength workouts. Consistency matters more than intensity.

No. AguaForce tops out at 11 lb per weight, which is ideal for toning, building strength and everyday fitness. Building bulk takes much heavier loads and a very different training plan.

Yes. It has no sharp edges, no rust, and weighs under 1 lb when empty.

It has no hard metal edges, and it's lighter at the low end than most dumbbells. As with any new exercise program, check with your doctor or physiotherapist first, especially if you're recovering from an injury.
