PowerBlock U33 Dumbbells Stage I (1lb - 21lb) Pair
Quick and convenient, the PowerBlock U33 set replaces 15 sets of "conventional" dumbbells.
PowerBlock was founded in 1991 by specialty fitness equipment designers who became friends while designing equipment for several companies including Parabody and Cybex. After two years of extensive testing, PowerBlock began sales of the newly coined "seelctorized dumbbell". Since then, PowerBlock has continued to be the leader in the fitness industry as they constantly strive to out do themselves in the pursuit of excellence.
