PowerBlock Personal Trainer Set 5 to 50 Pounds per Dumbbell

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 weight 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, turning your 3-pound dumbbell into a 6-pound dumbbell, or your 6-pound dumbbell into a 12-pound 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 weights are more compact and balanced than traditional dumbbells, with a padded handle that protects the wrists. Features: Has weight range from 10-50 lbs. Replaces 9 pairs of dumbbells or 540 lbs of free weights. Selector pin lets you change weights easily, just like with weight stack at the gym. More compact and balanced than traditional dumbbells; padded handle for wrist protection. Offers maximum weight of 50 pounds per hand.
