Water weight bag

Train with water — easy to carry, unstable load, maximum muscle activation.

About the product

The AQUAHIT water bag brings a revolutionary approach to strength training. Unlike traditional sand-filled bags, you carry it empty and fill it with water right at the training location — anywhere, anytime. As the water shifts with every movement, the bag's centre of gravity constantly changes, continuously engaging stabilising muscles and deep-core muscle groups. The result is a more intense and functional workout.

The bag is made of durable PVC with reinforced seams. Filling and draining is handled by a lockable valve with a tethered cap — the cap stays on the bag at all times. Four neoprene grip handles are specifically designed for the powerful javelin-throw grip: secure hold even on a wet bag surface, ideal for throws, lunges, and explosive power movements.

Why AQUAHIT?

Carry it light, train it heavy

Transport the empty bag — fill it with water on site. No compromises in portability, no compromises in performance.

Shifting load activates deep stabilisers

The liquid load shifts with every movement. Stabilising muscles fire on every rep, every exercise.

Grips designed for javelin training

Four neoprene handles shaped for the powerful grip used in javelin throwing. Secure even on a wet bag surface.
