Should You Buy Adjustable Dumbbells? – 4 Options

Adjustable dumbbells are both highly loved and commonly regretted, depending on user experience and expectations. A smaller athlete vs a larger lifter might have different perspectives. Space constraints, programming requirements, and other considerations will change what you think about adjustable dumbbells and whether they are a worthwhile purchase. So today lets dig into some of that, so we can figure out if they are the right addition for YOUR home gym, or not.

What Are Adjustable Dumbbells?

They come in a lot of shapes and sizes, but the basic concept is that you have fixed dumbbells, like you would find in a commercial gym. Where every weight change is a different dumbbell. And then you have adjustable dumbbells, where by means of any number of features, can change ONE dumbbell into multiple different weight options.

Why Would You Want Adjustable Dumbbells?

The number one reason, according to r/HomeGym, GGC participants, and home gym experts, is space saving. Smaller adjustable dumbbell sets don’t offer a TON of space saving, but there is some. A vertical dumbbell storage rack can hold a 5 to 50lb set in the same footprint as a set of 5-50lb adjustable dumbbells.

But when we get outside of that range, things start to get interesting. You often need a horizontal dumbbell rack for the 55 to 100 lb range, which means 2 to 3 times the space commitment. And if you get into some of the more unique adjustable dumbbell offerings, they can go up to 120lbs or more. Those 100+ lb dumbbells, especially if you are making 10lb jumps, take up a TON of space.

Another benefit for space, is that adjustable dumbbells often have carts on wheels. Meaning you can roll them around to where you need them, or get them out of the way when they aren’t in use or for cleaning purposes.

Cost can also be a factor. While adjustable dumbbells aren’t cheap, they are often cheaper than a full set of the same dumbbells. This cost savings is much like the space savings, as they get larger, they save even more money. A single pair of 120lbs dumbbells can cost as much as an adjustable dumbbell pair that go up to the same weight.

The last piece is really around usability. You can store a set of adjustable dumbbells in a closet, under a bed, next to a couch, in your trunk. You can use them and unlock a ton of movements. Pair them with a quality adjustable bench and you have a full functioning workout.

Why Would You NOT Want Adjustable Dumbbells?

Price is likely your first concern. If you only need a few specific dumbbells, then an adjustable set gives you a bunch of options you don’t need, which you are paying for. No matter what way you look at it, even if they are cheaper in some scenarios than fixed dumbbells, they are still expensive. The best options on the market are over $1000 and that is without a cart/storage option.

Fixed dumbbells, assuming you don’t buy anything too cheap, are solid pieces of iron/steel. There is often very little that can go wrong with a good set of fixed dumbbells. But adjustable dumbbells often have plastic dials, adjustment parts, and pieces prone to breaking and bending. This can be a cocern for those that like to drop their adjustable dumbbells, but also for general use. Bowflex has had to recall multiple iterations of their adjustable dumbbells over the years due to safety concerns with parts being damaged, leading to injury. And even higher priced and more reputable options from Powerblock and other companies specifically state NOT to drop them.

Some adjustable dumbbells are VERY quick to adjust. But those are also the most expensive. Others require frequent parts to be removed, plates to be added and adjusted, and parts to be added back on, often with twists, turns, and tightening. If you plan to perform multiple warm up sets and multiple working sets, this can add significant time to your workouts. If you have a training partner that isn’t using the same weights as you, that becomes an even bigger issue. And if you plan to perform any kind of supersets or drop sets, that can be a complete deal breaker.

Adjustable Dumbbells are also larger compared to their fixed dumbbell counterparts, meaning that an 80lb fixed dumbbell will be smaller than an 80lb adjustable dumbbell. This size can be troubling in terms of balance for things like bench press, where the longer the dumbbell is, the more of a “teeter-totter” effect it can have in your hands.

They can also be troubling for some smaller athletes, as even the smallest size is often quite a bit larger than a small dixed dumbbell. We’ve found issues over the years with my wife using them as well, as the larger sizes often require her to angle her hands for bench press variatons and other movements to not hit her chest. If you are a lady with a sizeable chest, you might run into some problems.

The last key consideration is about progress. For the larger lifters, some of the smaller sets can be limiting. Fixed dumbbells can go up to 200lbs, where as adjustable dumbbells don’t often go past 100lbs, with only very few maxing out at 120lbs.

What Kind Of Dumbbells Should YOU Buy?

The key considerations above should hopefully help you with the pros and cons. The last piece is finding the right solution for you, which can be 1 of 4 options.

Option 1 – Forget dumbbells entirely

They aren’t required, and I’ve gone entire programs without using them. If it wasn’t for dumbbell press variations, I wouldn’t use them very often in my own work. I do find that smaller athletes use them more often though. But skipping dumbbells entirely is a possible solution.

Option 2 – Fixed All The Way

Adjustable dumbbells are dumb, annoying, and reak of home gym weakness. Buying a full set of fixed dumbbells is the way to go. Its the only way you can use that Prime 4 Tier Dumbbell Rack with the sliding tray on the bottom, and you might as well grab the Intek Stainless Steel beauties with the self leveling logo plate.

Option 3 – Adjustable Dumbbells FTW

You are gonna save space, save money, and get everything you need in one compact package. Solid choice! If you want to explore the best options, you can read this article right here.

Option 4 – Combo Breaker!

There is a unique option, one that we employ, where you have a little bit of both. A set of 5 to 50lb dumbbells, either in 5lb increments or paired with some Micro Gainz Dumbbell plates, alongside a set of adjustable dumbbells that go up as heavy as possible, like the REP x Pepins, gives us a lot of opportunities and a best of both worlds solution.

With the smaller athletes that are in my gym, like my daughter and her friends, we have the ability for one kiddo to grab the 5s, another the 10s, another the 20s, and so on. You can have multiple athletes doing the same exercise, at the same time, without any downtime. And if two happen to use the same weight? The adjustable dumbbells help fill that gap too.

For the ladies in our gym, they rarely go above 40lbs on dumbbells for anything, as dumbbells are normally used for higher rep accessory work. So the fixed give them easy access to the best of the best without any set up or adjustments. And the adjustable dumbbells give them that upper limit for RDLs and hip thrust options.

For myself and the larger dudes in the gym, we get the fixed dumbbells for our easy warm-up sets, as well as drop sets and movements like lateral raises where you just don’t go past 20lb no matter who you are. And the adjustable dumbbells unlock the higher ranges without the footprint commitment or cost.

We serve every athlete in our space, we take up very minimal space doing it, but it obviously costs a bit more since we are doubling up. For us, this is the solution. But not for everyone.

👉 In short: “Adjustable Dumbbells are a smart compromise—not a perfect replacement.”
