Can You Put Water
in a Soccer Ball?
Yes — but most players do it wrong. Here's the right way.
The Short Answer: Yes
Filling a soccer ball with water is the most effective way to create a heavy training ball that maintains the exact size, shape and feel of a match ball. When filled correctly it even retains its bounce — allowing you to do rep after rep off a wall, something a medicine ball simply can't do.
This is overload training — the same principle elite specialists use to build the fast-twitch muscles required for a long throw-in. Train with resistance, switch back to a standard ball, and the difference is immediate.
Most DIY Attempts Go Wrong
Most players who try this without the right tool end up with leaky valves, a damaged ball bladder or — worst of all — an unbalanced ball where the water shifts around during training.
That unstable weight causes erratic movement and puts serious strain on your shoulder and elbow. If the ball doesn't react like a real soccer ball, you're not training — you're risking injury.
The Right Way to Do It
The Long Throw Coach Tap Adapter connects directly to any standard household tap and fills your ball in under two minutes with zero damage to the valve. No DIY hacks, no leaks, no risk.

Same size and feel as a match ball
The ball reacts to your hands and the ground exactly like a standard football — so everything you build in training transfers directly into your game.
It bounces — so you can do continuous reps
Just find a solid wall and throw rep after rep. No partner needed. A medicine ball can't do this.
No dangerous weight shift
Our specific filling method eliminates the sloshing effect found in DIY attempts, protecting your joints during explosive training.
Why It Works
Training with a heavier ball forces your muscles to work harder to produce the same movement. Switch back to a standard ball and it feels effortless — that contrast is where the extra distance comes from.
