The only dumbbell system that can 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 handle that 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. 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.
Handle: Straight cylindrical grip set inside a padded handle.
Side Rails: Color bands correspond with the weight chart on the handle for easy weight identification.
Selector Pin: Change weights quickly and easily with the secure magnetic polypropylene pin, rated for 500lbs. max load.
Dial Lock:Adjust in 2.5 lbs. increments by using the adder weights. Simply tilt the handle back and place the dial lock in the open position to gently remove the adder weights inside the lower ballast tubes, then close the dial lock and place the handle back in the set.
