Best Adjustable Dumbbells & TOP 15 Reviews 2019: From Powerblocks to the Ironmaster

4.9 (98.57%) 28 votes

I realize a rack full of heavy, tough, Hex dumbbells will make your gym look absolutely stacked.

But let’s be real here.

Not all of us home gym athletes have the space to stack a set of Hex weights against the wall. Sure they are great for bragging rights, Instagram selfies and oh…you can use them to lift too.

But for many folks, there is just not enough room.

That is where adjustable dumbbells come to the rescue. Personally, I think these bad boys look pretty cool too. The 90 lb Powerblock elite’s look downright intimidating!

If you have landed here, you are probably looking for a set of the best adjustable dumbbells.

You are in luck; we have compiled this guide which lays out what to look for before choosing a set, some simple yet effective adjustable dumbbell workouts to get you started, and a list of the 15 best adjustable dumbbells we could find, reviewed.

If you’re interested in adjustable dumbbells, you may have some questions about which dumbbells will work the best for you.

Here are a Few Things You Want to Consider before Deciding what Set is Right for You

Speed or time it takes to adjust

One reason fixed dumbbells are so well loved is they are easy. To change the weight, just pick up a different dumbbell.

Adjustable dumbbells have this one minor flaw. They take some time to adjust. For some, it is a few seconds, for others a bit longer.

You are a busy person. You value your time, right?

So look for a set of adjustable dumbbells that has a reputation for being easy peasy to adjust.

Weight – How much can you lift?

This seems like a no brainer, but I will mention it anyways. Adjustable dumbbell sets come in a pretty wide range of Min and Max weights.

Some sets max out at 25 lbs on each dumbbell and some max out at around 100 lbs.

If you need a dumbbell that weights more than 100 lbs, it is time to start looking at Olympic weights. They make Olympic dumbbell bars that can be loaded pretty heavy.

Shape. Hint: You want a Flat side

Picture this. You are lying on your bench, with the dumbbells still on the floor. You are really looking to challenge yourself, so you have 35 lbs (or whatever weight challenges you) stacked on each dumbbell.

Now you grab each dumbbell and place it on your thigh so you can maneuver them into position.

Now ask yourself, what do you want right now, around dumbbell or a dumbbell with a flat side?

Fixed hex dumbbells are so popular because they do not roll around and sit comfortably on your thigh as you get into position.

Now, you want those same benefits for adjustable dumbbells, especially if you lift heavy weights. Adjustable dumbbells with a flat edge are best, especially for heavy lifters.

The Dark side of Adjustable Dumbbells

Just like people, adjustable dumbbells are not perfect. They do have pitfalls you should be aware of.

  • You can’t, or more accurately, should not, drop adjustable dumbbells. They are not designed to hit the floor fully loaded. They can be damaged making them harder to adjust. Fixed dumbbells can be dropped, if you don’t mind damaging the floor.

Who drops dumbbells anyways?

People who lift to failure, that’s who. Challenging yourself and lifting a weight that is heavier than you normally lift could potentially lead to dropping the weight.

Olympic lifters routinely drop weighs.

Public Service Announcement: Video below shows Jeff from Athlean-X demonstrating the safe way to get into a bench press position when using heavy weights and he shows the proper way to drop dumbbells, if you should need to.

  • Adjustable weights have a “high” upfront cost, relative to fixed weights, which you can theoretically buy piece by piece.

But when you compare a nice set of fixed weight hex dumbbells with a set of high quality adjustable dumbbells, the cost difference is actually pretty small, or at least the sets prices all land in the same ballpark, more or less.

What’s to Love about Adjustable Dumbbell Sets?

The best thing about adjustable dumbbells.

Location, Location, location!

If the real estate you have to dedicate to your home gym is minuscule you may be interested in how little room adjustable dumbbells occupy.

Space savings are the biggest benefit to adjustable dumbbells, and it is a pretty compelling benefit to boot.

If you:

  • Live in a tiny apartment
  • Have Roommates that do not want the place decorated in early 80’s “Gold’s Gym” couture
  • Need to lift in your room
  • Have a very small home gym
  • Only have one corner of the garage to use as a gym
  • Lift in your office (or home office)
  • Live and lift in a College Dorm

Then adjustable dumbbells are the right choice for you!

Different Styles of Adjustable Dumbbells

Adjustable dumbbells can be adjusted using one of three adjustment styles.

Caps or collars

How does it work: With a cap or collar, you screw the collar off, add the weight plates to the bar, and screw the collar back on.


  • Least expensive adjustment style.


  • This style leaves the bar sticking out past the weight, so you can not rest the weight on your leg if you need to get into position.
  • Cap or collar adjustments take the longest to change or adjust. You have to take the time to unscrew the collar, load each plate, and screw the collar back on. Some may find this tedious.

Selector Pins

How does it work: With Selector pin dumbbells you place the pin in place at your desired amount of weight. When you lift the weight out of the holder, the plates you don’t want to use will stay behind.

Powerblocks use a pin style selector.


  • Fast weight adjustment.
  • Pin selector style dumbbells tend to be more compact than dial styles which are longer.
  • More organized than collar style, unused weights stay in the holder.


  • More expensive than collar style adjustment.


How does it work: Dial style adjustment dumbbells are the easiest to use.

You select the weight by dialing in your desired amount on the dumbbell, and the dial leaves the other weights behind. Bowflex and Stairmaster adjustable dumbbells use a dial style.


  • Easy to adjust.
  • Can be the fastest to adjust, especially on models that adjust both sides at the same time.
  • More organized than collar style, unused weights stay in the holder.
  • Dial styles such as those found on Bowflex, can be fine tuned to place a different weight on each side of the dumbbell.


  • More expensive than collar style.
