Can You Put Water in a Soccer Ball? Everything You Need to Know

If you want to add 10 to 20 yards to your throw-in, you need to train with resistance. Every elite specialist knows that “overload training” is the key to building the specific fast-twitch muscles required for a pitch-stretching launch. This leads many players to a common question: Can you put water in a soccer ball to make it heavier?

The Answer: Yes, But Most People Do It Wrong

The short answer is yes. Filling a soccer ball with water is the most effective way to create a “Heavy Ball” that maintains the exact size, grip, and texture of a match ball. In fact, when a ball is weighted correctly, it even retains its bounce, allowing for drills that medicine balls simply can’t handle.

However, most DIY attempts end in disaster. Players often end up with leaky valves, ruined ball bladders, or—worst of all—an imbalanced “sloshing” weight. If the water inside isn’t stabilised, it can lead to erratic movements that cause serious shoulder and elbow injuries. If the ball doesn’t react like a real soccer ball, you aren’t training; you’re just risking a trip to the physio.

The Solution: The Universal Tap Adapter

The easiest and only professional way to transform your gear is by using the Long Throw Coach Universal Tap Adapter. We designed this tool to bridge the gap between a standard tap and your soccer ball, allowing for a seamless, pressurised fill in under two minutes with zero damage to the valve.

But the adapter is only half the battle. To truly unlock the power of the Heavy Ball without risking injury, you need to know the professional secrets to internal balance and calibration.

Why the Long Throw Coach System is Different

When you use our adapter and follow the specific instructions included in our Online Training Course, your ball doesn’t just become heavy—it becomes a precision training tool. Our system ensures:

Standardised Weights: We show you how to hit the perfect marks (Size 3 becomes 3kg, Size 4 becomes 4kg, and Size 5 becomes 5kg).
True Mechanics: The ball reacts to the turf and your hands exactly like a match ball, because it maintains its elasticity and bounce.
Safety First: Our specific filling method eliminates the dangerous “weight shift” found in poorly made DIY balls, protecting your joints during explosive movements.

Testimonials

I worked with Frank whilst I played at Partick Thistle. As a full-back, I knew the importance of a long throw, and when Frank offered me the opportunity to learn a new technique which would add distance and accuracy to my current throw, I was delighted to get involved. We worked together for several months using Franks specially created heavier footballs. This allowed me to gain power and by the end of our period working together, the results were night and day. The team now had a long throw option and I had added another positive aspect to my game.

Motherwell FC and Scotland

I’ve witnessed at close-hand Frank’s techniques and the improvements they have brought to teammates who have now developed a long throw, which has positively affected the team. Not only has Frank taught his techniques in a clear and visual way but he uses video analysis to get his points across and offer feedback to players. Frank’s attention to detail is second to none and I would recommend any team or player who has the appetite to develop a long throw to get in touch with Frank.

Spartans FC

I couldn’t throw the ball into the 6-yard box before, but now I’m consistently reaching just inside the edge of it. The training has definitely helped a lot. With the right technique and the use of the heavy ball, I’ve seen significant improvements. My shoulders are sore after each session, but it’s a good kind of soreness, like a pump you get from a solid workout. The footage we’ve been taking really shows the progress I’ve made. I can see a noticeable difference in both distance and accuracy.
