PowerBlock The first and only “smart” (selectorized) dumbbells ever made. This is the hardcore muscle-building tool for the serious home trainer, and it only takes up a 2-foot-by-2-foot area. Each dumbbell is about the size of a shoe box. And because you change the weight in two seconds flat simply by moving pins, it’s like having more than 28 pairs of dumbbells in that tiny area.
