💪【HOW TO FILL】: Fill with water (under the tap or using the included tube - make sure the pin is DOWN for this), then open the pin UP to release the air, attach the pump, and start rocking it - the fuller it is, the heavier and more stable it becomes. Less water makes it lighter but less stable.
💪【IMPROVE FULL BODY STRENGTH AND BALANCE】: You will immediately feel its unstable characteristics during fitness. Even at the slightest angle of incline, the full weight of the water will swing from side to side. To raise it to the top of your head, even the smallest muscles are activated and work with the larger muscles to maintain balance and strength.
💪【STRAIN YOUR MUSCLES】: Do you want to experience the fun challenge of "live" or "weight"? Unlike "dead" weights, the tide tank will react to every movement you make. Therefore, each repetition is different, and each time you ask questions that are different for your muscles and motor control. This can train athletes to become strong and promote muscle growth for fitness enthusiasts.
💪【MAX. CAPACITY UP TO 55 LB】: The water bladder can be filled with up to 55 lbs (25 kg) of water. But don't focus too much on this weight. Even experienced fitness experts can only use it with a weight of 44 lbs (20 kg), but they will still experience muscle soreness. It's all about the workout. It's recommended to add a small amount of water until you can fully fill it. 💪【PORTABLE AND MULTIFUNCTIONAL】: Our fitness water tank uses a PVC shell. The empty water bag weighs only 1.4 kg, making it very portable. Most importantly, it's perfect for aerobic exercises, high-intensity interval training, home workouts, and all types of gymnastics, such as weightlifting, swinging, curling, cycling, and rowing.
