Water weighted medicine balls are an economical approach to Med-Ball training. An entire team can do upper body development and quickness drills at a fraction of the cost. Nozzle attachment to fill Hydro-Balls.

Using this little device to fill regular balls (rubber, basketballs, soccer, etc. ) with water is such an economical way to bring a lot of medicine balls into a training program. My team didn't have the $ to buy enough to let everyone use med-balls, but the hydro-nozzel solved that issue. We will buy real ones as the budget allows, but great way too start.
