PowerBlocks are only dumbbell system which expand to meet your strength needs, PowerBlock dumbbells are the most versatile and effective exercise tool ever developed for strength training. PowerBlocks work intuitively. Rather than requiring you to buy a room full of dumbbells, PowerBlocks act just like a weight stack at the gym, with a weight handle which fits inside the first weight, which fits inside the second, which fits inside the third, etc. When you want to change weights, you simply move the weight selector pin into the appropriate slot and you’re set. As you lift the core, all the weights above the selector pin are lifted at the same time, turning your 5kg dumbbell into a 10kg dumbbell. Not only is the system remarkably easy to use, but it’s also cost- and space-efficient, as a single pair of dumbbells can do the work of dozens.

The EXP series includes two 1kg adder weights within per handle to micro-load weight adjustments. Allowing you to fine-tune your dumbbells from a 10kg dumbbell (with 2 adder weights) to a 9 or 8kg dumbbell within seconds.

The Sport 90 EXP has a weight selection from 2-22.5kgs with optional Add-On Kits to take the weight to 31kgs (Stage 2) and 41kgs (Stage 3).
