Everything to know before you start.

A dumbbell is a dead, fixed mass. Water moves, resists and forces you to stabilise on every rep: more core, more grip, fewer jolts on the joints. And it adjusts litre by litre, then stores away when you're not training.

Up to 25 kg when filled to the brim. You set the load litre by litre by filling more or less: a few kilos to start, the full load for heavy sessions.

A high-resistance shell built for impacts, drops and repeated grips, without deforming or wearing out.

Several reinforced handles sewn onto the shell let you swing, clean, carry and throw it. No stand, no suspension: it is handled entirely by hand.

No. The bag is handheld: no stand, no mounting, no ceiling to reinforce. One clear square metre is enough to swing, clean and lift safely.

Swings, cleans, squats, lunges, carries, rotations, ground throws: complete functional full-body work. The free “AquaPower Program” PDF details sessions by level.

Yes, that's exactly its playground. Soft and water-filled, it sets down and drops to the floor without the crash of iron, without breaking or scratching anything. Your neighbours won't know you're training.

Yes. The fluid load and water-adjustable intensity make it a progressive-return, proprioception and stability tool used in clinics. Your physiotherapist remains the judge of the right protocol for your case.

With a regular garden hose or a shower head: filled in a few minutes, drained through the same valve. Empty, the bag rolls up and stores in a cupboard.
