Ironmaster Adjustable Dumbbells Review (Are They Any Good?)

When considering equipment for a home gym, space is always going to be a massive factor in your decision. Sure, it would be great if we could all fit a complete dumbbell set in our garage, but unfortunately, that just isn't possible for most of us. 

A great alternative to a full set of dumbbells is a high-quality pair of adjustable dumbbells. Designed to save space, they come equipped with a range of weights and a handle that allows you to attach different weights to suit your workout. 

One of our favorite sets of adjustable dumbbells is the Ironmaster Quick-Lock Dumbbells, so we thought we would write a review to showcase exactly why we love them so much. 

The Good 

  • The first big benefit of the Ironmaster Quick Locks is the insane build quality. They have fixed-width chrome finished handles with a strong, grippy knurl that makes them easy to lift and secure in the hand.  
  • The weight plates are also ergonomic, with a flat compact design and locking pins that result in dumbbells that are comfortable when resting on your thighs or chest during rest periods. They also grow in size, meaning beginners don't have to lift huge dumbbells until the weight starts rising. 
  • There is a considerable level of control over the exact weight that you are lifting. This means you can add increments as small as 2.5lbs via the easy-to-adjust system. They also rise all the way to 165lbs, which is more than enough for the majority of lifters seeking a huge endorphin release. 
  • The metal construction of the Ironmasters is finished for durability. This means less time cleaning and maintaining the weights. 
  • The 75lb set even comes with an awesome stand that not only holds your dumbbells but also holds all of your locking pins and plates. This makes them a no-brainer for those who want to maximize the space in their home gym. 
The Bad 
  • Even experienced lifters who have owned the Ironmasters for a while will find it hard to change the weights quicker than 20 seconds. This makes it hard for drop sets and exercises where you regularly change the weight of the lift. 
  • While completely worth the money, they are a bit pricey and may be slightly out of budget for those on a tight budget. 
  • Stock can be hard to come by as they are extremely popular. 

Unique Features Of The Ironmaster Adjustable Dumbbells

The Ironmaster Adjustable set of Dumbbells are one of Ironmasters’ flagship range of products. They are high-end and come with premium features that set them apart from the competition.  

Quick-Lock Design 

The quick lock design allows you to change the weight of each dumbbell extremely easily and quickly.

Go from 5-75lbs in under 20 seconds. This makes them some of the best adjustable dumbbells, if not the best on the market, for speed.

Heavy Duty Construction 

There are lots of cheaper adjustable dumbbell alternatives on the market, but most of them come with cheap plastic designs that feel clunky or badly made and flimsy.

The Ironmasters are in a whole new league, with heavy-duty construction that feels as good as traditional dumbbells in the hand. 

Chrome Plated Steel Handles With Knurled Grips 

Unlike cheaper brands, Ironmasters won’t rust and degrade. They have a chrome plating system surrounding a steel core. This makes them impervious to rust, no matter how sweaty you get during your workouts.

This also makes them exceedingly easy to clean. You also have a high-quality knurl that gives excellent grip, even when the weights are cranked up high.

Spinlock Collars To Secure Plates 

When it comes to adjustable dumbbells, there is nothing more annoying or even dangerous than spinning unsecured plates.

The Ironmasters utilize a special spinlock collar to prevent this, making them feel just as fixed as a traditional dumbbell.

Ergonomic Design 

As lifters, we have to constantly be on the lookout for the early signs of injury and stress.

Over our life, we will perform thousands of reps, which makes it especially important that we look at the ergonomics of our equipment. 

The Ironmasters are ergonomically designed to combat undue strain. This means you can lift harder for longer.

We are always on the lookout for the very best equipment for our home gyms. Finding products that tick both boxes in terms of quality and space is always difficult. 

The Ironmaster Adjustable Dumbbell system is one of the few products that we can recommend with all of our hearts.

These dumbbells feel exceptionally comfortable in hand during exercises thanks to the high-quality knurl and exceptional build quality.

The steel feels solid, and the plates don't move an inch, even when you are throwing up those last reps with less than perfect form. This means they don't move during the lift and don't cause instability. 

The stand is aesthetically pleasing, too, with an ode to old-school ironworks gyms. The iron-style construction looks really cool, too. We would have no problem giving it center stage in our home gym. 

The quick-change system is one of the quickest we have seen in any adjustable style dumbbell system, and while you won't be able to swap as quickly as you would with a full rack, the trade-off is definitely worth it for the space you save.

They feel just as good during a set of presses as they do during bicep and hammer curls, so you can rest comfortably knowing these dumbbells work just as well as any traditional ones. 

One thing we think is spectacular is the lifetime warranty that Ironmaster offers with this set of adjustable dumbbells. For products that have changeable plates and locking pins, you don't usually get this, but they are that certain you will be satisfied with these dumbbells that you are guaranteed for life. 

Ironmaster has exceptional customer service too, which is one of the many reasons they are so popular amongst lifters worldwide. You only need to read the thousands of reviews for them across the internet to know that they are highly regarded universally. 

The only gripe we could possibly find regarding the Ironmaster adjustable set is that they are fairly expensive. If you are a beginner or you have a tight budget, they may be out of reach. If you only make one big purchase, however, they would be a great one as they give you the functionality of a full rack of dumbbells for a lower price and with a space-saving profile. 

We love these dumbbells, and we give them a Garage Gym Pro seal of approval and recommendation. 

Comparisons With Ironmaster Adjustable Dumbbell Alternatives

Ironmaster Dumbbells vs Powerblocks 

The Powerblocks dumbbells are a much cheaper option compared to the Ironmasters, but they lack the build quality, stability, and aesthetics of the Ironmasters and don’t have a lifetime warranty or as good of a reputation. However, Powerblocks are still a really solid option if you are on a budget or just getting started with your setup.

Ironmaster Dumbbells vs Bowflex SelectTech  

The Bowflex SelectTech adjustable dumbbells are another cheaper alternative to the Ironmasters. Surprisingly, they do have excellent build quality for the price, but they feel a lot cheaper to use and are a lot more fiddly to change the weight on. 

They aren't really competition for the Ironmaster set but are an excellent alternative set for those who don’t have enough money to fork out on the complete and expensive Ironmaster set.
