Why You Should Buy an Adjustable Dumbbell Set to Improve Your Home Workouts (BUYERS GUIDE)

So you’ve decided that you want to get some adjustable dumbbells? Only a few months ago I was also in the same position where I’d had enough of the dumbbells I was using as they weren’t challenging enough. I mainly workout at home and need a range of weights so I can do some of the P90x3 workouts but my dumbbells at the time only went up to 10kg on each hand. I had limited space but never considered buying a good quality set because I thought I had seen more or less what adjustable dumbbells were on the market. To me an adjustable dumbbell only came in one mode and that was the cast iron ones with the iron discs that are locked in place by the spin lock.

It was only until I read what other adjustable dumbbells people used that I realised that there are so may different types available on the market that solve a lot of the problems that my cast iron dumbbell set had, such as speed of change and max weight. So if you are also looking for some dumbbells this guide is for you and I’ll take you through all the things to consider including letting you know which model I finally chose.


Features to Consider

If you are in the middle of setting up your own home gym, you need to make sure you are doing your research, and find quality equipment that will provide the type of training you are looking for. Before buying a lot of expensive equipment that may not give you the workout want, it’s important to consider the features of the equipment you are buying, and read their reviews to make sure it’s what you want in exercise equipment.


One of the first things to think about when buying adjustable dumbbells is the size that you want and how much room you have to store them. There are a wide range of plate and handlebars when you look at professional lifting sets that will increase your choices when you work out. Even though it is an attractive option, you also need to decide if you have enough room to store a big set. If you don’t you may want to just focus on the size weights that you need at the moment, and then add to the set later.

Styles and Types

This is where I was naive. I always assumed there were only the old fashioned cast iron dumbbells with the spin lock that hold the discs in place. Little did I know there were other dumbbells which offered quicker ways to change the weights around.


The Universal PowerPak Adjustable Dumbbells with Dial A Weight

The Universal PowerPak Adjustable Dumbbells with Dial A Weight

With this type, you are literally able to dial the amount of weight that you want to work out with. Once you dial the preferred weight, you can life up the barbells, and the chosen weight is just attached to the ends. Any extra plates will be left on the holder making this a convenient type of adjustable dumbbell, but very expensive.


A Spinlock Dumbbell

A spinning lock holds together multiple weight plates, and this is the most common type of adjustable dumbbell. This traditional set allows you to manually place your desired weight onto each end of the pole, and then you twist the metal lock until it is tight to keep the plates on without shifting. It is a more ungainly system than the dial-a-weight style, but it is a lot less expensive.

Selector Pin Dumbbells

Similar to the dial-a-weight as there isn’t any manual placement of the weights on the bar, but you do have to move a pin to choose the preferred weight that you wish to work with. After you choose your desired weight, the rest of the plates will remain on the holder. This is a great middle area of cost and convenience. The Powerblock Adjustable Dumbbells are known for using this method.

Max Weight

Depending on your preferences, you can purchase either lighter or heavier sets. Most adjustable dumbbells have a fifty pound per weight maximum, and a total weight maximum of one hundred pounds. It is important to purchase a set that can grow with you as you get stronger, instead of being stuck with a set that you have outgrown (i.e. what happened with me!)

Weight Increments

When considering a dumbbell set, make sure it is capable for making small and large weight adjustments. If you are looking at a set that makes adjustment in larger amount like twenty pounds, it will not help you when you are not lifting enough weight, but you can’t manage the additional twenty pounds yet. Look for a set that has increments in 5, 2.5, or 1.5-pounds, so that you can adjust your weight according to your fitness needs.


The good thing about the spin lock dumbbells is that you can usually buy small increments in whatever size you wish, however for the branded specialised adjustable dumbbells, you will have to move up or down in their predetermined weight increments. This is important because if you’re pushing close to your max at one weight and you only need an increase of 1.5 pounds the next time you lift but the dumbbells next increment is  10 pounds, you’re going struggle to get up to this weight.


When considering quality in an adjustable dumbbell set, you want to pick a high quality brand so that you know your training will be safe and reliable when you use them. If you find two sets that you are torn between and the brands and quality are similar, it is understandable to want to save some money and buy the cheaper set.


Do you want your dumbbells to be always out and on show and in a position to pick them up with ease or are you fine with storing them in your wardrobe?


Stands make it very easy and convenient to store your adjustable dumbbells, and this features can be a real bonus if you can afford it. They tend to be more expensive, but the convenience is great, Especially if you are using an area that is not set up as a home gym, but using is a small space of a room designated for another purpose.

No Stand

This less expensive option can also be an unwieldy problem when you are not using the dumbbells. If you have a basement or home gym, they won’t be in the way on the floor, so the lack of stand won’t be an issue.

Spending around a few hundred dollars on a set of good dumbbells that last a lifetime is a good deal.

Final Recommendation


In the end I went with the Powerblock Adjustable dumbbells. In particular I went with the Powerblock U90’s.

As I was doing my research the same two names kept being recommended over and over again and these were the Bowflex Selectech and the Powerblocks, so for me it was going to be one of these two that I would choose.


At first when I saw images of the two dumbbells I immediately looked at the bowflex selecttech and said, ‘They are the ones!’ Not because I can tell quality but because I couldn’t work out what the Powerblocks were. To me they looked a cross between a color printer and some sort of cooker, so naturally I leaned toward the Bowflex.

The other thing about the Bowflex was that they have a dial to choose what weight you want whilst the Powerblocks had some fiddly piece of plastic that you have to slot in carefully to get the right weight you want.

But what turned me back to the Powerblocks is that I read some people had experienced the plates becoming lose and putting themselves in danger. To be honest I have no idea how legitimate these claims are but a couple of them have surfaced. This was a major turn off.


The other major factor for me for not choosing the Bowflex was just how long the Bowflex Selectechs are. Even at low weights they are always the same length which to me look so long they resemble mini barbells. Even with my existing dumbbells (which weren’t that long in comparison) they had a metal rod that would catch on my clothes and when I would do fly’s they would smash together, i’d imagine it would be much worse with the Selectechs.

However with the Powerblocks they are incredible compact. If I want to do a dumbbell curl I can keep the dumbbell close to my body rather than having to spread my arms further out to accommodate the length. They are as long as how much weight is stacked on.

I do favor the dial a weight and the smaller increment jumps on the Bowflexs but not enough to turn me back to them.

Powerblock dumbbells have different ranges and I went for the U90’s which are the most expensive in the range. The reason I went with this particular Powerblock is that the u90s (as opposed to the u50’s) don’t really have a maximum weight as you can add another kit to it if you want to go over 90lbs whilst 50lbs is the max for the other version.

The other different is that you can get standard powerblocks without the ‘U’. The U stands for Urethane and provide a softer quieter experience rather than having the clanging plates of the standard models. I figured since I was spending so much I may as well get the ones I really want. Someone may choose this option if they work out early in the morning and don’t wish to wake anyone else in the house.

I hope that this guide has been useful and will help you choose the right dumbbell for you!
