# AguaForce > AguaForce makes adjustable water-filled weights: refillable plastic weights with three handles that work like a kettlebell or a dumbbell. You fill each one with tap water to any weight from 1 to 11 lb (0.5–5 kg), and empty it to store it, when it weighs under 1 lb. AguaForce sells online as a set of 2 for $39 USD, with free shipping to the United States and Canada, free returns and a 30-day money-back guarantee. AguaForce LLC sells one product directly to consumers at https://www.aguaforce.com/: the AguaForce Water-Filled Weights 2-pack in aqua. It is designed for home workouts, small living spaces, beginners, older adults, fitness instructors and aquatic (pool) fitness classes. Studios, gyms, pools and retailers can buy any quantity through the wholesale program. The website is one long home page, whose sections are linked below, plus a Terms of Use page and a Privacy Policy page. The free interactive exercise library is a separate site at https://cards.aguaforce.com/. **Key facts** - **Product:** AguaForce Water-Filled Weights, set of 2, aqua color. - **Price:** $39 USD per set of 2. Sales tax is calculated at checkout. - **Weight range:** each weight adjusts from 1 to 11 lb (0.5–5 kg). A set of 2 gives up to 22 lb combined. Empty, each weight weighs under 1 lb. - **How it adjusts:** open the lid, fill with tap water to the fill line for the weight you want, then close the lid firmly so the gasket seals. You can increase the load by as little as half a cup of water. No tools, plates or pins. - **Fill markings:** fill lines in both lb and kg are molded into the translucent body, so they never wear off and you can see the water level. - **Grip:** three handles, one on top and two on opposite sides. Hold it one-handed like a kettlebell, or grip both sides for crunches, squats and Pilates. The handles are smooth plastic with no metal knurling. - **Leak-proof:** a double-threaded screw cap with a silicone gasket seal. - **Material:** high-density polyethylene (HDPE), BPA-free. The resin meets FDA requirements for plastics that contact food (21 CFR 177.1520), confirmed by the manufacturer and by independent lab testing. It is impact-resistant, won't rust, and is not affected by pool chlorine or salt water. - **In the box:** 2 weights and a deck of exercise cards, plus access to the AguaForce exercise library at https://cards.aguaforce.com/. - **Shipping:** free on all online orders. Ships to the United States and Canada. Orders to Canada may owe import duties or brokerage fees. - **Returns:** free returns within 30 days of delivery, for one set per order. Return shipping for additional sets is at the buyer's cost. - **Guarantee:** a 30-day money-back guarantee if the weights break within 30 days of delivery. - **Ordering:** on the website through Stripe Checkout, up to 20 sets per order. Larger quantities go through the wholesale program. - **Limits:** the maximum is 11 lb per weight, so AguaForce suits toning, strength building, mobility, rehabilitation and everyday fitness, not heavy lifting. Empty it before leaving it anywhere below freezing. **Who it is for** - **Home workouts and core training:** one pair replaces a rack of dumbbells or kettlebells. The shifting water makes the core and stabilizing muscles work on every rep. - **Small spaces:** apartments, dorms, rentals, RVs and second homes. Empty, it fits on a closet shelf, under a bed or in a backpack. It has no metal to dent floors, mark walls or clang, so it is quiet enough for neighbors below. - **Beginners:** start empty or with 2 lb of water and add water as you get stronger. Plastic and water feel less intimidating than iron, and the moving water teaches slow, controlled reps. - **Older adults and active aging:** easy to start light and progress in small steps. The handles suit arthritic hands and a weak grip. The top handle sits higher off the floor than a dumbbell, so picking it up needs less bending. Many upper-body moves work from a chair. It supports light strength, mobility and balance training, and gradual loading after an injury. Check with a doctor or physiotherapist before starting a new program. - **Fitness instructors and personal trainers:** each participant fills to their own level, so one set serves a mixed-ability class. It suits circuit training, bootcamp, barre, Pilates, mobility, pre- and postnatal and senior classes. An empty class set is light enough to carry in a bag and fill on site. - **Aquatic fitness instructors:** used in shallow-water and deep-water aqua aerobics. Rule of thumb: when the weight stays mostly underwater, use it empty, because buoyancy and drag provide the resistance; when it comes mostly out of the water, as in lateral raises, fill it. It holds its shape under water and won't damage a pool floor if dropped. **How it compares with dumbbells and kettlebells** - One adjustable pair covers every weight from 1 to 11 lb, including in-between weights such as 7.5 or 8.5 lb that fixed sets skip. - It costs far less than a set of kettlebells or dumbbells and takes a fraction of the storage space. - A pound of water loads muscles exactly like a pound of iron. The difference is that water moves, which adds a stability challenge. Slow, controlled movements work best. - It has no hard metal edges and nothing to rust, so it is gentler on floors, walls, feet and toes. - It is not a replacement for heavy weights above 11 lb. **Exercises and workouts** AguaForce works the whole body: arms, chest, back, abs, glutes and legs. Example exercises are squats, goblet squats, lunges, weighted crunches, hip thrusts, swings, lateral raises, Russian twists, curls, overhead presses, Pilates and pool exercises. The included exercise cards are sorted into upper body, core and lower body sections, with the target muscles highlighted; pick one card from each section for a complete workout. The exercise library at https://cards.aguaforce.com/ covers glutes, core and abs, hamstrings, shoulders, back, quads, arms and calves. It runs in any phone, tablet or computer browser and can be installed to a home screen, with no app store needed. Two or three sessions a week is a good start for most beginners. **What customers say** Reviewers consistently mention zero leaks, easy storage, comfortable handles (including for small hands), fine-grained adjustability, good value compared with kettlebells, and helpful exercise cards. Several say the shifting water helps them focus and adds core work. The common caveats are the 11 lb maximum and that the water sloshes, so slow, steady movements work best. A pool instructor reports that participants of all ages grip it easily and that it gives good resistance both underwater and above it. **Frequently asked questions** - **What is AguaForce?** A refillable water-filled weight that works like a kettlebell or dumbbell.
