PowerBlock Sport Expansion Health Studies have shown that fishPowerBlocks are the easiest adjustable dumbbells to stretch out, so as your strength increases, so can they. If your PowerBlock is an 'EXP' model, you will be able to increase the weight of your set up to 90 lbs. An expandable model starts at 50 lbs and then gives the option to expand with two 20 lbs kits. The "Stage 2" kit increases the weight of a set from 50 lbs to 70 lbs, while the "Stage 3" kit increases the weight of a set from 70 lbs to 90 lbs.
