• Portable and Versatile: Our fitness water bag is perfect for cardio, high-intensity interval training for crossfit, and all athletic movements such as lifts, swings, curls, step-ups, and rows
• How to fill: Fill with water (under the tap or with the supplied tube - make sure the pin is down for this), then push the pin to the UP position to open it for air, attach the pump and start swinging it - the fuller it is, the heavier and more stable it becomes. Less water makes it lighter but more unstable
• Super Tough: Weighing only 2.8lbs when empty. Fitness water bags are easy to carry and prepare for exercise. Fitness water bags with water are super tough fitness sandbags filled with air and water. The valve facilitates the filling and emptying of the bag
