Revolution Dumbbell Concept
Posted on November 2nd, 2008 in Product Design
Designer Sang-Hoon Lee has presented digital barbell concept which could be useful if put into production. You adjust weight by rotating a dial, push a couple of buttons and smalls balls inside the dumbbell start to spin. When they spin fast enough, the desired weight is achieved. Although I doubt that creating such a dumbbell is physically possibe, the idea itself is really good.
