The water in the tank applies load at irregular intervals in two movements: "moving" and "stopping". This allows you to try to maintain balance with your whole body, stimulating your core and overall muscle strength. You can easily train your core and balance at home without going to the gym, such as during self-isolation. 【New sensation muscle training】Unlike training equipment such as dumbbells and barbells, the unstable characteristics of the water bag allow you to efficiently train your core. Therefore, it is ideal for increasing metabolism for dieting, creating a sleek body line, and building a foundation for various sports. 【Adjustable weight, space-saving】With a water volume guide line, you can set the weight that suits you, so anyone can easily do various training regardless of gender. When not in use, you can remove the water and air and fold it compactly, so it doesn't take up much storage space. 【Reliable and comprehensive support】365-day warranty after purchase. Returns and refunds are OK for customer convenience. We make every effort to ensure the quality of our products, but if you find any defective products or have any concerns, please contact us and we will respond promptly within 12 hours.
