No time. No space. No appetite for the gym.
The gym, without the gym.
A garden hose, 25 kilos of water, and every session starts the second you feel like it. Strength, cardio, explosiveness — no commute, no membership, no iron cluttering the room.
02 / 03
One weight, endless possibilities
From 5 to 25 kg in seconds. Add or remove water to match the load to your level. The perfect tool for progressive overload.

Your portable gym
Empty it, fold it, take it anywhere. Gentle on your joints on impact, relentless on your muscles.
Three reasons to switch to water
- 01
• Dynamic instability •
The water moves with you. Every movement forces your deep stabilizing muscles to engage.
- 02
• Rotational power •
The water's mass transfer builds explosive power and a crushing grip through rotations.
- 03
• Absolute versatility •
One single tool to build your strength, endurance and explosiveness.
S6 — Three worlds
Three arenas, one bag.
Video — home training (15–30 s, coming)
A complete gym in one square metre.
- Cardio, strength and explosiveness in one session, zero commute.
- Sets down and drops without a crash: training stays neighbour-friendly.
- Drains and rolls up: it disappears into a cupboard between sessions.
Video — physiotherapy clinic (15–30 s, coming)
A rehab tool with adjustable intensity.
- Fluid, unstable load: progressive return without joint jolts.
- Living mass: proprioception, stability and core work on every rep.
- Intensity dosed litre by litre, from post-op to return to sport.
Video — strength & combat prep (15–30 s, coming)
The explosiveness iron can't give.
- The liquid mass moves and resists — a force transfer close to real combat.
- Swings, cleans and explosive throws without wrecking wrists or elbows.
- Grip, rotation, core: clinch and throw work in real conditions.

Several reinforced handles sewn onto the shell to swing, clean, carry and throw the bag. The exact grip configuration will be specified with the final characteristics.
Exact list to be confirmed by the manufacturer: bag, fill manual and exercise guide. Any additional item will be detailed here.
Typical fill time to be confirmed. Fill and drain through the valve with a regular hose; no special daily care.
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.
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.
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.
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.
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.
