If it weren’t for lack of motivation and the trouble managing a set of dumbbells, I’d be one buff guy, for serious ya’ll! The Revolution Dumbbell enables you to digitally adjust weight by rotating a dial and pushing a couple buttons. 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. I need this now.
