This creative water bottle adopts a realistic dumbbell appearance design, which perfectly combines daily drinking water storage and lightweight strength training. Users can inject water or sand into the interior to increase weight, turning it into a temporary small dumbbell for arm exercises, shoulder training and simple fitness movements during outdoor sports, home workouts and office breaks.
Made of thick food-grade safe plastic, the bottle body is sturdy, drop-resistant and pressure-resistant. The sealed screw cap effectively prevents liquid leakage when carried in a backpack or gym bag. Large-capacity inner space meets the drinking water demand for long-time running, hiking, gym training and outdoor activities.
It is a practical two-in-one gadget for fitness lovers, which can be used as both a daily water cup and a portable adjustable weight dumbbell.
