【HOW TO FILL】:Fill w Water (under the faucet or under the provided tube-make sure the pin is DOWN for this), then open the pin UPWARDS to open the air, attache the pump and start rocking it – the fuller it is, the heavier and more stable it becomes. Less water makes it lighter but more unstable.
【IMPROVE FULL-BODY STRENGTH AND BALANCE】：You will immediately feel its unstable characteristics during fitness. Even at the smallest angle of inclination, the total weight of the water swayed from one side to the other. In order to raise it to the top of the head, the smallest muscles are also activated and work with the larger muscles to maintain balance and strength.
【MAKE YOUR MUSCLES STRONGER】：Do you want to experience the fun challenge of “live”? Weight? Contrary to “death” weight, the tidal tank will react to every movement you make. Therefore, each repetition is different, and each time you ask about things that are different from your muscles and motor control. This can train athletes to become strong, and promote muscle growth for fitness enthusiasts.
