The MX Select Adjustable Dumbbells are available in 35-, 55-, and now 85-pound increments and were one of the original, quick-change adjustable dumbbells. After using them over the past year and comparing them to the dozens of competitors we have on hand, I have mixed feelings.
In this MX Select Adjustable Dumbbells review, I’ll tell you the good and the not-so-good about this piece of home gym equipment. Like everything, there is plenty to love, but also things that could be improved upon if later iterations were to come out.

Why You Should Trust Us
With tons of adjustable dumbbells on the market today, it isn’t surprising that I’ve been excited to get my hands on dozens of them to try. As the number of home gyms and home gym setups has increased, so too has the number of dumbbells that take up little space, but have a wide weight capacity range.
I’ve tried dozens of top-rated dumbbells, so I know the main things fitness nerds like myself are looking for in a good pair. Aspects like durability, overall value, weight range, shape, and warranty are all things I take into consideration before recommending a product.

A Quick Look at the MX Select Adjustable Dumbbells
The MX Select Adjustable Dumbbells and, most notably, the MX55 Dumbbells, are quick to change, compact, and balanced while training. The issue isn’t whether they’re a quality dumbbell, but that since their inception, there have been many that have improved on the design and done so at a lower cost to the consumer.
If you’re wondering how the MX55 Select Dumbbells stack up against the likes of the NUOBELLs, Powerblocks and Ironmasters, stay tuned as we cover all this and more.
Coop’s Tips Before You Buy:
- MX has adjustable dumbbells that cap out at 30, 55, and 80 pounds. This is useful if you want to use more or less weight.
- Please don’t drop these. You’ll probably start crying because you’ll have thrown hundreds of dollars down the drain when they inevitably get damaged from the fall.

Is the MX Select Adjustable Dumbbells Worth It?
Let’s get into the meat and potatoes of the review at the jump. Should you pick up the MX Select Dumbbells or go with one of the many other adjustable dumbbell options on the market for your home gym? Here is what I recommend.
Great for:
- Those that want a rather fast-changing dumbbell that takes up little space.
- People who don’t want to lift heavier than 80 pounds per dumbbell.
- Trainees that don’t like the feeling of a uniquely shaped dumbbell like the Powerblock dumbbells, but would prefer something more familiar.
Not recommended for:
- If you’re cost-conscious, then I recommend looking at other options (more on those later) as these aren’t the best value.
- Heavy lifters who want a heavier max weight

Using the MX Select Adjustable Dumbbells
Adjustable dumbbells like the MX Selects are some of the best home gym equipment we recommend. Although we think barbells are fantastic, similar to some of the best kettlebells, dumbbells present a wide range of potential exercises in an extremely compact form. The MX Selects, and particularly the MX55 Selectorized Dumbbells that we brought in for review, hit this nail on the head.
Changing the Weight on the MX Select Adjustable Dumbbells
In an extremely small footprint, the MX55’s can go from 10 to 55 pounds (in 5-pound increments) with the turn of a dial.
The dial I allude to is the first thing most people notice when they see the MX dumbbells. The Weight Selector Dial lists numbers 1-10 and corresponds with the Weight Legend found on the cradle system. The dial must be changed separately on both sides of the dumbbell to get the desired weight, which does take more time than, say NUOBELLs, but not significantly more.
To adjust the weight, you must first depress the Weight Selector Release Button, which then pops up the dial. This is all a pretty quick and smart process that is somewhat satisfying during a training session.
Storage
One accessory that is pretty much a necessity for most is the Dumbbell System Weight Stand. It works with the MX30, MX55, plus the MX85’s and allows the dumbbells to sit off the floor, making them easier to remove or put back in place. The entire system and stand create an attractive, modern design that would look good in a garage gym like mine or in someone’s spare bedroom.
After you select your weight and plunge the dials in, you simply grab the handles and pull the dumbbells out. There are two lips on each weight plate that secures into the ones next to them while an internal rod (that is adjusted via the dial) keeps them from falling off. This is an ingenious solution that keeps the plates secure without overcomplication.
In Use
When pulled off the stand and placed on your knees before laying back on a weight bench for bench press, the flat ends sit comfortably on your quads. During press or curls, the MX55’s feel very balanced and comfortable even at their max weight. This isn’t often the case with rapid-change dumbbells, as they’re known to have long handles that feel unwieldy and unique shapes that aren’t as balanced.
When you’re done with your set and want to change the weight or simply finish your workout, you place the dumbbells back in the cradles. Although this does take a bit of skill at first, over time the handles get easier to place in their slots.
Construction
Gym equipment gets used and abused, even if you’re taking extra precautions. Here’s what makes up the MX Select Rapid Change Dumbbell System.
The Handles
Conjoining the two heads of the dumbbell heads together is the handle. Approaching the MX Selects for the first time during a training session, the steel knurled handle was great to use. I personally prefer knurled, straight handles which is why the fixed set in my garage are the REP Rubber Hex Head Dumbbells that we’ve reviewed.
Although my set and all of the ones I’ve seen on the market use a knurled handle, MX Selects now come standard with a contoured grip handle that is antimicrobial. It’s understandable that they would offer an antimicrobial option with the amount of germs in the gym, but 99% of adjustable dumbbells are used in a home gym setting by a single user or a couple of people that are family.
I wish the knurled handle was still available as an option, but maybe that’s something that can be done in the future.
Weight Selection System
Each dumbbell has two plastic dials with the numbers 1-10 listed on top. They’re quick to change and are satisfying to use. The dials extend a metal rod that’s inside of the handle to capture the desired amount of plates.
Weight Plates
Each end of the MX dumbbell handle has weight plates. These plates have a steel core that is coated in polyamide nylon. Nylon makes for a quiet dumbbell during training that also lasts a long time.
Weight Rack and Cradle
The cradle that the dumbbell sits in is bent steel that’s been powder coated in silver gloss paint. It looks good and prevents corrosion.

NÜOBELL Adjustable Dumbbells
Product Highlights
- All-in-one adjustable dumbbell
- Weight ranges from 5 to 80 lbs
- Easy to use
- Feels like a standard dumbbell
Pros & Cons
Pros
- Feels like a regular dumbbell in hand
- Easy quick-change adjustments
- Knurled handle
- Comes with a stand
Cons
- Can be tricky to get in the stand
- Unsure of structural integrity
- Pricey
Bottom Line
These are great for people who want an easily adjustable dumbbell pair that feels more like a traditional fixed dumbbell
The dumbbells that are most similar to MX Selects are NUOBELLs. It would seem that the creators of NUOBELLs saw the popularity and smart design of MX55 and tried to improve the functionality. Both of these dumbbells are using similarly designed internal mechanisms that utilize metal rods to select the correct amount of weight.
Although MX Select’s were the original, NUOBELL’s are faster to change, go heavier (except for the latest MX85 release,) and are cheaper on a dollar per pound basis. Neither is able to be dropped and both have their quirks when it comes to placing the handles back in the weight stack.
I like both options, but if you want a heavier dumbbell, then we prefer NUOBELL’s over MX Selects.
I suggest checking out our in-depth review of NUOBELL Dumbbells for more details.

Customer Experience
The warranty provided on these dumbbells is 12 months. This is okay, but not exceptional for something you’ll be paying over $500 for. If you order through Amazon, you’ll be able to return these within 30 days of receiving them, provided you don’t send them back in used condition.
On the MX Select website, there is an option to contact the brand with any questions you have. However, they do encourage you to read through the FAQs before sending an email inquiry. I was disappointed to note that they do not have a live chat option.
Ordering the MX Select Adjustable Dumbbells
We received the MX55 and MX80 dumbbells to review. Both showed up in branded cardboard boxes with strapping. Each box had a large red “DO NOT DROP” sticker that delivery drivers like to ignore, but the boxes were all in pretty fair shape.
Each dumbbell sat in styrofoam encasing within their box and was wrapped in plastic.
Although there was some minor cosmetic damage to the boxes that happened during shipping, the dumbbells themselves looked pristine and untouched.
I was a happy lifter.
Customer Reviews
On Amazon, the MX Select Adjustable Dumbbells have an overall rating of 4.6 out of 5 with close to 55 reviews. Customers love the helpful stand, easy adjustment, and their typical dumbbell shape, which can be uncommon with adjustable dumbbells. One positive review from someone with the screen name “The Bullfighter” said this: “If you’re not looking to go over 55lbs and want to save space and money, this is it. Highly recommended.”
On the other hand, some customers felt that these adjustable dumbbells were getting stuck in the stand if you put them in slightly crooked at all. Others also mentioned that you should absolutely not drop these when weightlifting because you could compromise the durability of the dumbbells.
Final Verdict of Our MX Select Adjustable Dumbbells Review
Overall, I would recommend the MX Select Adjustable Dumbbells if you’re looking for a solid option with a traditional fixed dumbbell shape. However, if you’re looking for a heavier expandable option or want to be able to drop your dumbbells, these are not the best option for you. I do think they are a solid buy and you likely would not be disappointed with your purchase if you decide to go with the MX Selects, provided you’re not on a super tight budget.

Do the MX Select Adjustable Dumbbells come with a warranty?
Yes, they come with a 1 year warranty.

What kind of training routine should I do using the MX Select MX55 Adjustable Dumbbells?
You can use this weight set for a variety of things when doing a home workout. These include things like squats, deadlifts, curls, or pretty much anything you’d do with a traditional fixed dumbbell.

How do you know what dumbbell weight to use?
Again, this all comes down to personal preference and what your fitness level is. Like with any fitness equipment, play around with the different options and see what feels challenging but not impossible. This is a great place to start.
Are MX Select Adjustable Dumbbells a good option for beginners
Actually, yes. The MX Select Adjustable Dumbbells are shaped like a traditional dumbbell, so you don’t have to change your form at all, unlike uniquely-shaped adjustable dumbbells such as the PowerBlock Adjustable Dumbbells.
