Bench Dumbbell

Bench dumbbell systems have been around for ages, but back then they didn’t allow you to “digitally adjust the weight by rotating a dial and pushing a couple buttons.” Click here for first picture in gallery.

Inside are tiny balls that spin. The faster they spin, the more weight is generated. No mention on how much energy would be required to power such a novel idea but that’s just all in the logistics.
