Product Description

SportBlock 24 Features: Product Type: -Dumbbells. Quantity: -Set. Adjustable: -Yes. -SportBlock 24 dumbbells set. -Attractive silver finish complements modern decor. Dimensions: Overall Height - Top to Bottom: -5". Overall Width - Side to Side: -10.5". Overall Depth - Front to Back: -5.25". Overall Product Weight: -48 lbs.

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.

This pair of SportBlock 24x3 dumbbells, for instance, adjusts from 3 to 24 pounds in 3-pound increments (3, 6, 9, 12, 15, 18, 21, and 24 pounds), in effect doing the job of 16 individual weights. Even better, the weights are more compact and balanced than traditional dumbbells, with a padded handle that protects people with weak wrists. Best of all, the free weights are terrific whether you're trying to build muscle mass, firm and tone your physique, or get rid of unwanted body fat. The SportBlock set offers a maximum weight of 24 pounds per hand and carries a limited 10-year warranty.

I wish I could give stars in halves; this product would get a solid 4.5 from me. Rounding up to a 5 would mean folks who aren't taking the time to read the review might assume that there's really no room for improvement, but there is.

After reading this review you might think I work for Powerblock or something, but I don't. When you're spending between $150-400 on a set of "high performance" adjustable dumbbells, applying a bit of logic can go a long way for your satisfaction and safety.


To help counteract the perceived bias I might have, I'm gonna try something different; I'm going to start with the CONS of the Powerblocks.

1. The magnets in the selector pin could be stronger. As a safety measure, there are magnets in the pin that hold it against the bars on the side of the weight stack, reducing the chance of it slipping out during an exercise. This makes a lot of sense, but the magnets are pretty weak. During some pretty basic exercises the magnets will come lose and lose their hold. Now don't get freaked out -- it's not like the pin flies out and it's scary to work out (there is an elastic band acting as a backup safety also). I'm talking like millimeters here; I can see that the pin has moved just enough where you can tell the magnets aren't holding. Rather than a whole bunch of cheap magnets within the pin, two small high-quality earth magnets would give a better hold while still being pretty easy to remove.

2. The weight selection process can be a bit finicky on carpet or non-flat surfaces. Because there may be a bit of shift in the weight stack on carpet, sometimes it's tricky to stick the weight pin in correctly.

The power block dumbbells is my first adjustable dumbbell set i have bought. I love the size of it as i can store it just about anywhere and yet be able to lift weight anywhere from 6-24 pounds. The only problem with it as others have mentioned is that you might mess up getting the pin in straight to adjust the weights but it is easy to figure out when u have messed it up. Another annoying thing about the dumbbells set is while ur working out the plate hit each other and u hear an annoying clunking sound

I really like this product because it is compact and not as cumbersome as the larger sets. For most people, this will suit their needs and they can get an upgradable set later on. The small size allows almost everyone to perform conventional exercises with proper form. With the larger PowerBlocks, this is a concern because of added bulk and length.

The square shape of these dumbbells allows the manufacturer to put more weight in a smaller place. This makes these much smaller than other rounded adjustable dumbbells over the same weight range and increments.

From a safety perspective, I also think these are the safest and most rugged adjustable dumbbells. However, this does not mean that nothing can go wrong. You need to be conscious of inserting the pins straight across and the pin mechanism right side up so the magnets engage to hold the pins together. There is a also a backup elastic band to prevent a plate from falling, but this might not save you in an overhead triceps extension.

This product is rugged and well made. It is less likely to break then some other brands and the concept is simple behind how the adjustments work. In other words, there are less things to break or go wrong and I believe these can take a fairly hard fall and still be fine. I haven't dropped mine, but I base this assumption on the way they are designed and the quality of the materials and how they are put together.

I would definitely purchase these if you do circuit training and want to keep your pulse up. If you become serious, you can buy an expandable set over a larger range later. This is great entry point product.

My Fiancé bought me this set for Xmas and I absolutely love them. I live in a 1 bedroom condo and I was running out of room in my living room for all my dumbbells. I can already see me saving to get the next size up...which I'm sure I'll be needing before next year.

I have very small hands and the grips on these are just perfect to grasp them. Another thing I was worried about was placing them on my shoulders...they don't fit up there perfectly, but they don't fit up there uncomfortably either.

Another thing is they aren't incredibly cumbersome. When you get out of 20 pounders, the dumbbell ends become thick and big and hard for my little hands to grasp...not a problem with my powerblocks...Then ends are always easy to grasp and seem to stay the same size through the increments...which is perfect for my extra small hands.

I work out to Videos and have to pause the video in order to change the pin to a different weight, but it didn't take me long to get used to changing the pin into the correct increment and I'm getting faster with it all the time.

I've been slowly giving away my dumbbells because they just aren't needed anymore and I can't say enough about the powerblock...can't wait to buy my next set.

I'm thinking though that a stand would make changing increments easier...but for now...I'll make do.
