At first glance, the above pic looks like a pen or flashlight on steroids, but it's much more then just that. They're actually dumbbells, for those who weight train. Created by designer Sang-Hoon Lee, these dumbbells allow you to change the weight digitally, to your own preference.
What happens is, the bars let you increase or decrease the weight of the dumbbell by simply rotating a dial and punching a few buttons. The dumbbells themselves have tiny balls inside that spin to generate weight, and the faster they spin, the more weight is generated which of course, basically means that you will no longer have to change or add plates to your dumbbells when you work out. Pretty unbelievable!
