Same-size dumbbells
Same-size dumbbells

The dumbbell has a shell structure of the same size, changing the overall weight of the dumbbell by changing the volume of the internal components. When exercising, none of the trainers could judge the weight of the dumbbells by the appearance, so no one is anxious because of contrast.
The universal shell enables the dumbbell to be installed uniformly after manufacturing, reducing the production cost to some extent. and this sustainable design concept also be considered for reducing waste, and reusing the dumbbells.
