Walk into any gym and what is one of the main components that stands out the most? A giant rack of Dumbbells that runs the length of the gym. This is, of course, a must for any gym, but it takes up a tonne of space.

If you workout at home, or want to start working out at home, you need something that’s just a bit more compact. This is where Adjustable Dumbbells fit in nicely. And as you know from our post on equipment necessities for working out at home, these are a must.

Now if have never heard of these before, then where do you start? And if you have heard of them, then the same question applies… What’s the Best Adjustable Dumbbell?

There are a number of different companies out there now that make Adjustable Dumbbells. We will review 3 popular brands that we feel are the best to choose from.

To be honest with you, they are all good. They all adjust easily and are reasonably priced. What really matters is what you do with them once you get them. But that’s where we come in here at youtrainyou.com, so don’t worry about that!

There are some differences between the brands of Adjustable Dumbbells, and we’ll do our best to help explain them to you. At the end of the review, we will give you our top choice for what we feel are the best Adjustable Dumbbells.

Okay, let’s get started.

PowerBlock Adjustable Dumbbells – The World’s Best Dumbbell?

*Note: Powerblock makes a number of different models of Adjustable Dumbbells. We will cover 3 different models in this review*

Are they REALLY the World’s Best Dumbbell? 

That’s the slogan for Powerblock; they claim to be the World’s Best Dumbbell. And to be honest, it’s hard to argue with that statement. I have owned my own set of Powerblock Sport 90’s (adjust from 5-90lbs each) for 10 years. I bought them in 2009 when I started training clients in their homes. I needed something compact and convenient that I could carry in with me, and Powerblock Dumbbells fit the bill perfectly.

After about 5-6 years, I decided to keep my first set in my home for my own workouts and purchased a second set for working with clients.

Shelley has a set for herself as well. She has the Powerblock Sport 50’s, very similar to the ones we are reviewing, just an older model as she purchased hers in 2013. Shelley’s still look the same as the day she bought them, and they have been through hundreds of workouts, a testament to their durability.

As I mentioned above, Powerblock makes a number of different models of Adjustable Dumbbells. They even make an Adjustable Kettlebell! For the purpose of this review, we will be covering three models of Adjustable Dumbbells:

  1. Powerblock Sport 24
  2. Powerblock Sport 50
  3. Powerblock EXP Stage 1, 2 and 3


Powerblock Sport 24

Product Review: Powerblock Sport 24Powerblock Sport 24 Adjustable Dumbbells

Price: $159.99 (USD) plus shipping

Where to Buy: Amazon.com

Warranty: Limited 10 Year Warranty

Weight Adjustment: 3-24lbs in 3lb increments: 3lbs, 6lbs, 9lbs, 12lbs, 15lbs, 18lbs, 21lbs, 24lbs

Our Rating: 7.5 out of 10


Key Features of the Powerblock Sport 24

The Powerblock Sport 24 is arguably the most compact of Adjustable Dumbbells. The weight can be easily changed with a plastic pin that slides in and out of the slots on the weight. They are also designed to make the same small 3lb increment in weight all the way up to a max of 24lbs for each Dumbbell.

That may not seem like very much weight, but it may be just right for certain people, and for certain exercises. I know I have had elderly deconditioned clients in the past that I have recommended these for. The Powerblock Sport 24’s could also come in handy for isolation exercises for the arms and shoulders (rotator cuff and scapular stability exercises), where appropriate.

They are certainly the cheapest of the Adjustable Dumbbells, costing $159.99 (USD) plus shipping costs. That is, of course, because they only adjust to about half, or less, of what other Adjustable Dumbbells increase to.

Any Cons to the Powerblock Sport 24?

Adjustable Weights that go up to 24lbs each are pretty neat, but the average person is going to need more weight within a few weeks to a few months of beginning a structured strength training program. I can honestly say I can count on two hands the number of clients I’ve had in 12 years that I have not needed more than 24lbs with.

I’m not saying these Adjustable Weights can’t be useful for some people, they definitely can. All I mean is that if you really want to focus on getting stronger, at some point, you are going to need more weight than what the Powerblock Sport 24’s offer.

Powerblock Sport 50

Product Review: Powerblock Sport 50                   Powerblock Sport 50 Adjustable Dumbbells

Price: $338.95 (USD) plus shipping

Where to Buy: Amazon.com

Warranty: Limited 10 Year Warranty

Weight Adjustment: 10-50lbs in 5lb increments (10lbs, 15lbs, 20lbs, 25lbs, 30lbs, 35lbs, 40lbs, 45lbs, 50lbs)

Our Rating: 9 out of 10

Key Features of the Powerblock Sport 50

The most attractive feature of the Poweblock 50’s is that they adjust easily from 10-50lbs. They have the same pin as the Powerblock Sport 24’s that slides in and out of slots on the dumbbells, and are labeled with the weight you select. You are essentially gaining a half rack of dumbbells: 10’s, 15’s, 20’s, 25’s, 30’s, 35’s, 40’s, 45’s, and 50’s.

If you were to purchase these Dumbbells individually, it would cost you a lot more $$$$. I just did some quick Math on Amazon.com and it comes to $620.82 (USD), and that doesn’t include shipping costs! You would also need a fair bit more space, which brings me to my next point…

They are also pretty compact. This is the set that Shelley owns. Hers are an older model, but they are essentially the same, except for the color and the pin that is used to select the weight.  It is a little different on the newer models. The previous model had a metal pin that selects the weight.

The newer model has a plastic pin that selects the weight. It’s a little different, but it hasn’t changed the solid feel of when a weight is selected

Another nice feature of the Powerblocks is that they do not require a “base” to adjust the weight on the fly. Every other brand of easily Adjustable Dumbbells have a base that they need to rest in to adjust the weights.

Any Cons to the Powerblock Sport 50?

As great as the Powerblock Adjustable Dumbbells are, they do have a few downsides that are worth mentioning:

Well we can tell you that for a beginner, increasing weight from 15-20lbs for an exercise can be quite a jump for certain exercises. Even if you are not a beginner, and you are doing an exercise that requires lighter weights, a 5lb jump can almost feel like too much. Having the option of increasing by 2.5lbs is very beneficial in these situations.

There is one last thing that I don’t like about the Powerblock Dumbbells. Their design is definitely brilliant, however it doesn’t allow for holding a Dumbbell in what we call the “Goblet” position for anything over 20-25lbs.

What’s a Goblet Position?

The Goblet position is when you hold a Dumbbell with two hands against your chest, right under your chin. This position is extremely beneficial for teaching a proper Squat or Split Squat, as it encourages an upright posture while performing the exercises. It can essentially coach you how to do a movement better, just from the placement of the Dumbbell.

This is a considerable downside if you want to perform any number of lower body exercises in the Goblet position (Squats, Split Squats, Rear Foot Elevated Split Squats, Single Leg Squats, and Reverse/Walking/Forward Lunges).

To be clear, you can still perform most of these exercises by holding weights at your sides, however due to their design, The Powerblock Sport 50’s do have some limitations.

Powerblock EXP Stages 1, 2 and 3

Our Rating: 9.5 out of 10

Key Features of the Powerblock EXP Stages 1, 2 and 3

So these are the best Adjustable Dumbbells Powerblock offers. Let me explain how they work. They are essentially just one set of Adjustable Dumbbells that you can purchase two expansion kits for.

The Powerblock EXP Stage 1 set looks almost identical to the Powerblock Sport 50. The difference is they have two metal removable inserts that weigh 2.5lbs each built right into the handle itself. This is what allows the Powerblock EXP Stage 1 Adjustable Dumbbells to do 2.5lb jumps at certain weights (7.5, 17.5, 27.5, 37.5, and 47.5lbs).

Powerblock EXP Stage 1 Adjustable Dumbbells


The Powerblock EXP Stage 2 set is literally just two more sets of the rectangular plates that the Powerblock EXP Stage 1’s fit down inside. It now allows you to work up to 70lbs for each dumbbell. You can purchase the EXP Stage 2 Expansion Kit plates alone (pic on the left), or as a full set if you don’t own the EXP Stage 1 already (pic on the right).

Powerblock EXP Stage 2 Expansion Kit 55-70lbs

Powerblock EXP Stage 2 Adjustable Dumbbells 5-70lbs












As you might be able to guess, the Powerblock EXP Stage 3 Expansion set is two more sets of the rectangular plates that the Powerblock EXP Stage 1 and 2 fit down inside, bringing your total up to 90lbs for each Dumbbell. Now you basically own an entire rack of Dumbbells that take up a whole wall in a gym, but they can fit next to your end table in your living room. That’s where mine are.

You can purchase the EXP Stage 3 Expansion Kit alone (pic on the left), if you already have the EXP Stage 1 and 2, or all three sets at once (pic on the right):

Powerblock EXP Stage 3 Expansion 75-90lbs

Powerblock EXP Stage 3 Adjustable Dumbbells 5-90lbs










Now you are going to pay a handsome price to own these weights, but in comparison to purchasing an entire rack of Dumbbells, plus the rack to store them on, and a new room in your house to fit them in, you are saving a very large sum of money by investing in the PowerBlock EXP Stage 3. They are the best investment I have ever made for working at home.

Any Cons to the Powerblock EXP Stages 1, 2, and 3

It’s hard to think of any Cons when I think about an Adjustable Dumbbell that replaces an entire rack of Dumbbells. I guess the only real setback with the Powerblock EXP Stages 1, 2, and 3 is that they are the most expensive of all the Adjustable Dumbbells.

I should also mention that the EXP series have their own downside to weight increases as well. While they can adjust in 2.5lb increments, they can’t do it for every jump in weight. Allow me to explain:

The EXP Stage 1 series adjusts as follows (I’m using the EXP Stage 1 as they go up to 50lbs like the Sport 50’s):

5lbs, 7.5lbs, 10lbs, 15lbs, 17.5lbs, 20lbs, 25lbs, 27.5lbs, 30lbs, 35lbs, 37.5lbs, 40lbs, 45lbs, 47.5lbs, and 50lb

As you can see, because of the way the weight inserts work, and the design of the Dumbbell, you can only make 2.5lb jumps some of the time. Again this is a little unfortunate, as a 10-15lb, 20-25lb, 30-35lb, and 40-45lb increase can be a big jump depending on the exercise.

I know this may not seem like a massive concern, but it’s just something to consider before you make a purchase that you can literally own for the rest of your life if you take care of them.

Bowflex SelectTech 552 Adjustable Dumbbells


Key Features of the Bowflex SelectTech 552

Do you remember how Bowflex started? I’m sure we all remember seeing the original Bowflex infomercials. That cool looking home gym machine with those giant bendable rods flexing as some super fit man or woman did all kinds of strength training exercises while smiling.

I mean, who could forget that testimonial from the “so called” Grandmother! I was only a kid at the time, but did I ever want one!

Well Bowflex is still around, and like any good business they have evolved with the times. They have grown to make the treadclimber (a hybrid between a treadmill and stepper), as well as a very popular set of Adjustable Dumbbells.

They have, by far, the most customer reviews on Amazon.com. And while I don’t own a set of these, I have used them when working with clients that had them in their home.

The Bowflex Adjustable Dumbbells easily adjust with turn dials on the ends of the dumbbell. They can adjust from 5lbs up to 52.5lbs. As I listed in the breakdown above, they increase by 2.5lbs for the first 25lbs, then 5lbs after that.

I like this feature because, unlike the PowerBlock Sport 50, you can use 12.5, 17.5, and 22.5lbs. From our explanation above, I see this as a real benefit for beginners, as well exercises requiring smaller jumps with smaller weights.

Another thing that you can do with the Bowflex SelectTech 552, that you can’t with any of the PowerBlock models, is the Goblet Position. As you know from what I wrote with talking about the Powerblocks, I’m a Big Fan of the Goblet position.

Well thanks to the dial design of the Bowflex Dumbbells, they look more like a typical Dumbbell. You can perform all those great knee dominant exercises in the Goblet Position. That’s a huge point in the favor of Bowflex to me.

Any Cons to the Bowflex SelectTech 552

Based on what you have read above, you might be thinking why Shelley and I don’t own a set of Bowflex Adjustable Dumbbells?

At the time I purchased my Powerblock Dumbbells, the Bowflex Adjustable Dumbbells required a fairly large stand to operate. That wasn’t going to work for something that needed to fit in my trunk.. lol

Now they have a much smaller base that they rest in, but they still do require this base. It’s much better than it was, but I do have to give Powerblock the leg up here, as they require no base to operate.

I also don’t like that the Blowflex SelectTech 552 only make 2.5lb jumps up to 25lbs. Again, this is better than the Powerblock Sport 50, but I would like if they made 2.5lb jumps the whole way through. It’s a really nice way to make small progressions in your program.

There is one more thing that is really important to mention. When I used the Bowflex Adjustable Dumbbells that my client owned something very concerning used to happen. The plates would sometimes fall out of the handle while she was using them. Luckily she was never hurt, but this is obviously dangerous.

Now I worked with this client at least 7-8 years ago in her home, so I was hoping that Bowflex would have fixed this design flaw. Unfortunately, after combing through reviews on Amazon, I saw the same complaint from a few people. Now there are thousands of reviews, and I only found a few that said this happened, but it’s definitely worth considering if you are looking to purchase the Bowflex SelectTech 552.

The Warranty offered by Bowflex is also not as long as Powerblocks. Two years is decent, but it’s not as good as a ten-year warranty that’s offered by PowerBlock. I will also say that the design of Powerblock may not look as sleek and modern as Bowflex, but they do appear more durable in my opinion.

Bowflex SelectTech 1090 Adjustable Dumbbells

Product Review: Bowflex SelectTech 1090 Adjustable Dumbbells

Price: $299.00 – $424.58 (USD) plus shipping

Where to Buy: Amazon.com

Warranty: 2 Year Warranty on weight plates and parts

Weight Adjustment: 10-90lbs in 5lb increments (10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90lbs)

Our Rating: 8.5 out of 10








Key Features of the Bowflex SelectTech 1090

The Bowflex SelectTech 1090 is comparable to the Powerblock EXP Stage 3. Both sets of Dumbbells adjust up to a max of 90lbs, which is plenty of weight for even advanced trainees.

These Dumbbells have the same quick adjusting dial on the ends of the Dumbbells, allowing adjusting of weights very easily and conveniently between exercises.

The Bowflex SelectTech 1090’s adjust in 5lb increments, starting at 10lbs. Just like the Powerblocks, this replaces almost an entire rack of Dumbbells you would find in a gym. From what I have seen on Amazon, you are going to pay less for the Bowflex Adjustable Dumbbells.

Just like the SelectTech 552’s, the design of these Dumbbells looks more like traditional Dumbbell than the Powerblock, allowing you to perform lower body exercises in the Goblet position that can be very beneficial for beginners.

If I were looking to purchase a set of Bowflex Adjustable Dumbbells, my biggest concern would be the reviews I’ve read about the plates falling off the handles while people have been working out (as I mentioned, I experienced this as well with a set a former client of mine had). This could be potentially very dangerous.

The other side of this is that most of the reviews I read had all good things to say about the Bowflex Adjustable Dumbbells. Many of these people, said that as long as you are careful with the Dumbbells this shouldn’t happen.

Any Cons to the Bowflex SelectTech 1090

The very thing I really liked about the Bowflex SelectTech 552’s is that for the first 25lbs the Dumbbells adjusted in 2.5lb increments. Unfortunately this is not the case with the SelectTech1090’s, as they adjust in 5lb increments from 10 to 90lbs.

I know I have already said this, but those little 2.5lb jumps you can make in the first 25lbs, can be very beneficial for a beginner, or for exercises that may require smaller jumps in weight. Again, it’s not a huge concern, just something to consider when making a big purchase.

The two-year warranty on both sets of Bowflex SelectTech Adjustable Dumbbells is a little concerning to me as well, especially after reading the reviews about the plates slipping off the handles while people have been performing exercises. To me, Dumbbells should last a lifetime, if they are taken care of, so it makes me question how much Bowflex believe in their own product if they only offer a two warranty.

The advantage definitely goes to Powerblock here, as they offer a ten-year on all their Adjustable Dumbbells.

The last thing I wanted to mention about the Bowflex Adjustable Dumbbells was the reviews in which people reported the weight plates falling off the handles while working out. It seemed that the design of the 1090’s was not quite as good as the 552’s. And although, it was reported happening with both models, I read more report of it, with the 1090’s.

The culprit seemed to be a plastic clip on the 1090’s that the handle latches on to when selecting the weight you want. The plastic clip was wearing away rather quickly, causing the weight plates to slip off.

The Bowflex SelectTech 552’s have a metal clip on the weight plates that the handle latches on to, giving them a more durable attachment. Now from what I read, it seems that the 1090’s now have the same metal clip on the plates. This should definitely help with the weight plates not slipping off.

I’ll be checking the reviews over time, as Shelley and I are considering a set of Bowflex SelectTech Dumbbells.

Merax Deluxe 71.5lbs Adjustable Dial Dumbbells

Product Review: Merax Deluxe 71.5lbs Adjustable Dial Dumbbells

Price: $299.99 – $429.99 (USD) plus shipping

Where to Buy: Amazon.com

Warranty: 2 Year Warranty on weight plates and parts

Weight Adjustment: 11-71.5lbs (weights are labeled in KG’s) in 5.5lb increments (11, 16.5, 22, 27.5, 33, 38.5, 44, 49.5, 55, 60.5, 66, 71.5lbs)

Our Rating: 9 out of 10


Merax Deluxe 71.5lbs Adjustable Dial Dumbbell



Key Features of the Merax Deluxe 71.5lbs Adjustable Dial Dumbbells

The Merax Deluxe 71.5lbs Adjustable Dumbbells look very similar to the Bowflex SelectTech Adjustable Dumbbells. They have more of the typical Dumbbell look, and have the same dial adjusting system on the ends of the Dumbbells. I really like that the plates are made of metal vs. plastic. It allows for a more compact weight.

In fact, Bowflex have been so successful with their dial design Adjustable Dumbbells, it seems that all other manufacturer’s have tried to mimic their design in some way, except for Powerblock.

The Merax do have one key difference from all the Adjustable Dumbbells. Their weight is labeled in KG’s instead of LBS. This really doesn’t mean much, just download a conversion chart, or use a calculator for your first few workouts.. lol:

Weight in KG’s = Weight in LBS/2.2 (Easy enough)

If you are looking at pure cost, the Merax Adjustable Dumbbells are around the same price, or even cheaper than the Bowflex SelectTech 552, however they give you more weight for your money. The Merax Deluxe adjust up to 71.5lbs per Dumbbell. This is plenty of weight for many trainees, and comparable to the Powerblock EXP Stage 2, that adjust up to 70lbs per Dumbbell.

As I have mentioned with the Bowflex Adjustable Dumbbells, the design of the Merax Deluxe Dumbbell also allows you to perform exercises in the very beneficial Goblet position. I know I have mentioned this position a lot, but it really is great for beginners to maintain an upright posture during lower body knee dominant exercises. This scores big points for me as compared to the Powerblocks.

The last feature that is worth mentioning for the Merax Adjustable Dumbbell is that the dial only needs to be adjusted on one side in order adjusting of the weight. This makes them a little more efficient than the Bowflex SelectTech.

I read every review on Amazon for the Merax Deluxe 71.5lb Adjustable Dial Dumbbells (there were 109 in total), and it seems like everyone is saying great things about them. I believe I only read one or two reviews that referenced the plates slipping off the handles. This is much better than what I read from Bowflex.

There customer services seems great as well. Any issues people had with their weights, and there weren’t many, were handled immediately. Good customer service is everything in my opinion.

Any Cons to the Merax Deluxe 71.5lbs Adjustable Dial Dumbbell

After reading all the reviews on the Merax Adjustable Dumbbells, I have to say, I am very impressed with these. The point of this review is to help you make the best decision for your needs, so I do have to be as critical as possible.

The weight increments for the Merax Deluxe Adjustable Dumbbells is the largest of the all the Dumbbells we have reviewed in this article. They adjust by 2.5kg, not 2.5lbs. Let’s do a little math:

2.5kg x 2.2 = 5.5lbs

Now I know this doesn’t seem like a big deal, and in the grand scheme of things it’s not really. But if you are a beginner, I can promise you that the jumps from 10 to 15lbs, 15 to 20lbs, 20 to 25lbs are big. Having the option of doing 12.5, 17.5, and 22.5lbs is a bonus. The Bowflex SelectTech 552 is the only Adjustable Dumbbell that has this option. Hates off to Bowflex here.

The Merax Deluxe 71.5lbs Adjustable Dial Dumbbells also require the base they come with adjusting of weights. Powerblock has the only design that does not require a base adjusting of the weights. Again, this is not a big deal, but you can look at it as something else that can break.

Speaking of things breaking, the Merax have a two-year warranty, similar to the Bowflex. I don’t like the two-year warranty. Adjustable Dumbbells should last as long as you want them to, as long as you take care of them. Powerblock’s warranty is fives times longer. That’s a company that knows the quality of their product. I’ve had my Powerblock’s for 10 years this year, and they work as good as the day I bought them.

Who’s the Winner?

From all the features we covered above with each brand of Adjustable Dumbbell, and all the Cons we listed for each one, how do we pick a winner?

Well to be honest with you, to a certain extent, it comes down to personal preference, how much you are willing or able to spend, and how much weight you feel you will need.

So let’s pick a winner for 50lbs, 70lbs, and 90lbs…

The Best 50lb Adjustable Dumbbell

If a set of 50lb Dumbbells is going to be enough for you, and for many people it will be, I would recommend the Bowflex SelectTech 552 Adjustable Dumbbells. Why?

Bowflex SelectTech 552 Adjustable Dumbbells

I really like the 2.5lb increments all the way up to 25lbs. They are the only Adjustable Dumbbell of the brands we reviewed, that have this option. As we continue with our content on helping you build your workout programs, you will notice we encourage new trainees to take their time increasing weight, and to increase by 2.5 or 5lbs only if possible.

They are reasonably priced (all Adjustable Dumbbells are if you compare the cost of a rack of Dumbbells up to 50lbs), very easy to use, and because of their typical Dumbbell design allow for the Goblet Position. Powerblocks design does not allow for this.

They also go up to 52.5lbs each, just a nice little extra than Powerblocks 50lbs with the Sport 50.

Bowflex has also seemed to have corrected the issue with plates slipping off the 552’s.

And I know you might be thinking about that 2 year warranty, and I don’t blame you. Just take care of them, don’t ever drop them, or bang them down into the base or stand if you decide to get one. If you do all these few things to take extra care of your weights, they should last as long as you want them to.

The Best 70lb Adjustable Dumbbell

I’m sorry Merax, but Powerblock wins this round! The Merax Adjustable Dumbbell seems like a really nice Adjustable Dumbbell, and had a lot of great reviews, but I just like the Powerblock a little more.

Powerblock EXP Stage 2 Adjustable Dumbbells 5-70lbs

Perhaps it’s because I own a set of Powerblocks, and love them. I could be a little biased here yes, but also consider these few points.

The Powerblock EXP Series can adjust, at times by 2.5lbs (7.5, 17.5, 27.5, 37.5, 47.5, 57.5, 67.5lbs). I really like the smaller adjustments you can make with these. The smallest increment in weight the Merax can make is 5.5lbs.

The Powerblock EXP Series has 3 stages. You can eventually purchase Stage 3 that allows you adjust from 75 up to 90lbs. Once you develop enough strength that you require 70lb Dumbbells in each hand, you’re going to want to continue to progress. You don’t have that option with the Merax Adjustable Dumbbells. 71.5lbs is a lot of weight, but that’s it.

The Merax are cheaper than the Powerblocks, a lot cheaper, but they don’t have as many years under their belt as Powerblock. They were the first easily Adjustable Dumbbells, and they know the quality of their products. Hence, the ten-year warranty, vs. the two warranty with Merax. That’s a big difference.

The Best 90lb Adjustable Dumbbell

Powerblock EXP Stage 3, hands down. I’m sorry Bowflex SelectTech 1090’s, but I read too many reviews of falling plates to believe in this product. Now they do seem to have hopefully corrected the issue with a metal clip on their plates that grip the handle, instead of plastic one that can wear away, but it’s just not worth the risk.

Powerblock EXP Stage 3 Adjustable Dumbbells 5-90lbs

You will pay a lot more for the Powerblock EXP Stage 3, but you will also get their ten-year warranty, as opposed to 2 years with Bowflex.

You won’t be able to do the Goblet Position, which is a downside, but don’t worry, youtrainyou.com will give you lots of lower body strength training exercises, and coaching tips to help build strong, muscular, lean legs.

Don’t forget you will also have the option of making 2.5 jumps in weight at times, thanks to the design of the Powerblocks, as opposed to 5lb jumps only with the Bowflex SelectTech 1090.

Powerblock holds true to their slogan. They really are the World’s Best Dumbbell.
