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?

About a year ago I was also in the same position where I got to the point where I’d had enough of the dumbbells I was using. They were the cheap kind of adjustable dumbbells that cost around £30 and come in a plastic case. Even though they worked, they weren’t satisfying to use, and the nut to hold the weights together kept loosening.

I never considered buying a better quality dumbbell and used the same one for years since I believed I had seen everything the adjustable dumbbell market had to offer at the time. 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.

Lol and Behold: There are many Types of Adjustable Dumbbells!

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. Many of them also 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 When Buying An Adjustable Dumbbell Set

Before jumping in head first and buying any old set of weights, you will need to think and plan ahead. For example what kind of workouts are the weights for? Are you looking to build some serious muscles or are they for rehabilitation exercises?

In this section, you’ll see some of the factors you may want to consider before making your final choice of adjustable dumbbells.

1) How Much Room Do You Have To Store Your Weights?

One of the first things to think about when buying adjustable dumbbells is the max weight 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 of weights that you need at the moment, and then add to the set later.

2) The Styles and Type of  Adjustable Dumbbell Set

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.

– 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 dumbbells, and the chosen weight attaches to the ends. Any extra plates will be left on the holder making this a convenient type of adjustable dumbbell.

One of the most popular dial-a-weight dumbells is the Bowflex SelectTech 552.

– Spin-lock

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 hold them in place by twisting a metal lock until it is tight.

It is a more ungainly system than the dial-a-weight style, but it is a lot less expensive. These types will tend to be cast iron.

– 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 (reviewed below) are known for using this method.

3. Maximum Weight You Want To Lift

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)

4. Weight Increments

When considering a dumbbell set, make sure it is capable for making small and large weight adjustments. You want the adjustable dumbbells to be able to handle large increments when you need to switch from a light weight to a heavy weight, for instance if you are moving from a tricep exercise to a squat. However, it is also important for your adjustable dumbbell set to be able to handle small changes so that you can slowly progress through the weights as you get stronger in a particular exercise.

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 a particular weight, and you only need an increase of 1.5 pounds for your next session, it’s not going to be helpful if the next weight increment is 10 pounds or larger. Reviewing the weight increments is an important factor you don’t want to forget to take into consideration.

5. Quality & Budget

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. The last thing you would want is for a weight to come loose and smash you in the face or on your feet.

Spending a bit more on a good quality set rather than a cheap set is advisable when it comes to adjustable dumbbells.

6. Storage Method

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?

– Stand

  • Convenient attractive storage option for your set
  • Puts blocks at a proper height for lifting
  • Stand can hold weights up to 130 lbs in each...

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.

The better brands of adjustable dumbbells will usually have a stand that you can buy with the dumbbells as a bundle, or buy seperately.

– 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.

The Top 5 Adjustable Dumbbells

As I was doing my research the same names kept coming up as recommended dumbbells. Not surprisingly these were the sets that made the list.

What I had decided when I was looking for a set for myself, was that I didn’t mind spending a significant amount of money on these weights. I figured that a good quality pair would last me a life time and therefore any high prices wouldn’t scare me away. I believed that they would become a valuable investment. Spending around a few hundred pounds or dollars on a set of good dumbbells that last a lifetime is always better than going for a cheap pair that cause frustration and break easily.

Narrowing the Choices Down: SelectTech vs PowerBlock

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

Watch the video below for a comparison between the two.

At first when I saw images of the two dumbbells I immediately looked at the Bowflex SelectTech and said, ‘those are the ones!’ Not because I can tell quality but because I couldn’t work out what the PowerBlocks were or how they even worked.

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 on the SelectTechs coming loose whilst using them. 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 in length the Bowflex SelectTechs 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 spinlock dumbbells 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 SelectTechs because they look a lot longer.

However with the PowerBlocks they are incredibly 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. With the PowerBlocks, they get longer as the weight increases.

My Choice of Adjustable Dumbbell: PowerBlock U90’s

After all my research in the end I went with the PowerBlock Adjustable dumbbells. In particular I went with the PowerBlock U90’s.

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

My Delivered PowerBlocks

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.
