Aqua bag is a training exercise tool that allows you to adjust your weight by adding water to your muscles and core exercises at once. The water in the white eye stimulates all the muscles in our body in response to the minute movement of the body, enabling more effective training. In order to balance the movement of water, the core muscles of our body, such as our back and abdomen, are stimulated. You can adjust the amount of water up to 40 kg and easily adjust the weight according to the desired intensity of exercise. Even if you drop it during exercise with high-quality and super-strong materials, the air absorbs shock into the white eye, so there is no worry about injury at all. Upgrade your training to an aqua bag that is actually used in sports sites that require deceleration and acceleration stabilization. Aqua bag allows fun and performance training, so not only general fitness centers but also professional athletes are satisfied and use aqua bag.
