"We do a lot of strengthening exercises for protecting the joints and the ligaments. It helps me stay fit and perform well. Fluid X is an essential tool for this kind of stability training."
You have iron for raw strength. But for mobility, stability, and group logistics, static weights weigh you down.
See why Fluid X is the smarter choice for mobile training and space-limited studios.

Hardware & Durability
Fluid X bags are designed for drops and throws, but they are not "slam balls." While the commercial-grade PVC is incredibly durable for standard strength and conditioning use (cleans, snatches, tosses) on gym flooring or turf, we recommend avoiding repetitive, high-velocity slams on concrete to maximize the lifespan of the seams.
The difference is Dead Weight vs. Live Weight. Sand settles at the bottom of the bag, becoming stable and "dead." Water sloshes continuously, creating "live" momentum that reacts to your movement. This forces the user to engage more stabilizer muscles and core strength to control the object, providing a higher neuromuscular stimulus than sand.
Our gear is engineered for the elements. We use 1000D Reinforced PVC–the same material used in inflatable rescue boats. It is UV-resistant, waterproof, and abrasion-resistant, making it safe for use on grass, sand, and outdoor bootcamp surfaces.
Training & Usage
The weight is fully adjustable via the water level:
Coach's Tip: Due to the "Live Weight" instability, a 15kg aqua bag feels significantly heavier and harder to lift than a 15kg dumbbell.
Air provides structure and control.
It's actually very easy. We recommend adding a small amount of bleach to the water to prevent buildup. This keeps the bag low-maintenance, requiring just a simple drain-and-fill refresh monthly to keep it in top shape.
Business & Warranty
Yes. We offer a 1-Year Commercial Warranty on all professional bundles. This covers seam integrity, valve function, and material defects under normal training conditions.
Yes. Unlike nylon sandbags or leather medicine balls which absorb sweat and bacteria, our PVC surface is non-porous. It can be wiped down instantly with standard gym disinfectant or sanitizing wipes between clients.
