PowerBlock Sport Adjustable Dumbbell Set 24 lb & 50 lb Overview
The PowerBlock Sport 24 lb Dumbbell Set and the PowerBlock 50 lb Adjustable Dumbbell Set comprise anti-corrosive chip and scratch-resistant steel weight plates and rods with a durable gray enamel finish.
Their handles have a neoprene rubber foam coating that provides a comfortable and secure grip. The finish also helps to wick away sweat and prevent blisters.
The dumbbells’ polyurethane selector pins are incredibly robust and can support more than the highest weight on offer.
Both sets are made in the USA. They come with a 10-year warranty covering free repair or replacement if a material or workmanship defect develops.
They function in the same manner. The only real difference between the two sets is the starting weight, the increments, and the end weight capacity. Their appearance is also a little different.
The PowerBlock Sport 24 Dumbbell Set gives access to weights from 3 lb to 24 lbs, increasing in 3-pound increments. It allows you to work with a pair of 3, 6, 9, 12, 15, 18, 21, and 24 lb weights.
The 24 lb set is color-coded, making it super-easy to select the weight you want to use.
Each dumbbell has a different colored insert on the sides that designates a different weight. To select the right weight for the exercise you want to do, match the color to the one on the chart atop the cradle.
The PowerBlock 50 lb Adjustable Dumbbell Set allows you to work with between 10 lb and 50 lb of weight in 5-pound increments.
This gives you a pair of weights weighing 10, 15, 20, 25, 30, 35, 40, 45, and 50 lbs. It is not color-coded. The handles feature a red trim that lists the weight of each.
With both sets, swapping to another weight couldn’t be more simple. Just pull the selector pin’s handle to remove it from the cradle, then insert it into the slot that correlates to the new weight you want to use.
Magnets and an elastic band system will lock the dumbbell into position. It will then be ready to lift, with those you are not using remaining in the cradle.
Adjustments take around four or five seconds at most. This makes the sets ideal to use with workout programs such as P90X, ChaLEAN Extreme, and the like.
If you’re looking for a convenient way to store your dumbbells, check out the small PowerBlock Compact Weight Stand. It is perfect to use with either of the weight sets.
Measuring 20″ (W) x 24″ (H) x 18″ (D), it weighs 14 lbs, it can support up to 100 pounds. It folds flat if you want to store it.
Things to be aware of
These dumbbells are approximately 30% smaller than most other adjustable dumbbells.
As a result, they take up less space and are easier to lift out of the cradle.
However, this may present a downside for some in that people with very large hands may find using smaller dumbbells restricts their movement when doing exercises such as Dumbbell Curls.
Their construction does not make it possible to load additional weight.
If you buy the 24 lb set, that is the maximum weight you will be able to lift. Buy the 50 lb set, and you won’t be able to add more weight to it.
When you place the weight back in its cradle, be sure to align it properly. This will make switching to another weight faster and smoother.
