The PowerBlock Elite are uniquely designed dumbbells, made in the US. Although the price can get very high, you get very durable fitness equipment that will serve you for years to come.
Pro Versatile and expandable
The PowerBlock Elite dumbbell weight plates are a mix of 2.5 and 5 lbs increments, ranging from 5 to 50 pounds. After you've reached the point where 50 lbs seem too light, you can buy an expansion, increasing the weight up to 90 lbs. You can use these for both strength and conditioning exercises, and they will last for a long time.
Pro Easy to change weight
There is no fancy mechanism - you just pull a metal 'fork' out of each dumbbell and place it where you need to. The weight plates are color coded, and correspond with a color coded chart on the side of each dumbbell. It might take some getting used to, but once you're familiar with it, changing weight plates would take about 5-10 seconds for each dumbbell.
Con Changing weight plates with shaky hands could take slightly longer than on dial-adjustable dumbbells
If you've done, for example, 3 reps of your workout and you want to change the weight of your dumbbells to less, your hands could be a bit shaky at this point. This would make inserting the adjuster 'fork' more fidgety than with a dial, but it's not a dealbreaker.
