Are Ironmaster Quick-Lock dumbbells the best in the home gym fitness industry? Our in-depth, detailed review will take a look at all the of pros and cons of the highly rated adjustable dumbbells, from build quality, weight range, to adjustability. You can be sure to get an honest opinion from Jays Home Gym.

We’ll even have a look at the awesome stand Ironmaster sell with their 75lb dumbbells pair, nothing will be missed out in our Ironmaster review.

Natural Fixed Weight Dumbbell Feel

When you spend this kind of money on a pair of adjustable dumbbells, one of your first concerns should be, can I do all the exercises I normally can with fixed weight dumbbells? Are they going to feel natural or awkward?

I’m speaking here of their size, if the dumbbell handles are too long they’re going to get in the way when dumbbell benching or overhead pressing, if the plates are too large” bulky” will they get in the way of curls and hit your chest? And you will be happy to hear with the Ironmaster pair do not.

It’s great to see that Ironmaster, unlike a few other reputable brands, has thought their design through thoroughly, and with their compact design, you should have no issues with the above, first big thumbs up to Ironmaster.

The 75lb set should be heavy enough for most users, the Ironmaster adjustable dumbbells are intended for the more experienced of lifters, but there is nothing wrong with a beginner starting out with a heavy duty set like the Ironmasters.

As many people will know reading this review, your first set of dumbbells are quickly grown out of. I started with a 50lb York set 20yrs ago and outgrew them in 6 months, I couldn’t fit any more weights on the handles if I remember correctly, and if you are looking at some of the other adjustable sets in this range you might want to be careful, because unlike the Ironmaster pair, a few of them do not let you add addition plates.

So firstly if you are a beginner or you are looking to upgrade, be aware of a weight range that will allow expansion packs for future growth and secondly please do not splash out $600 on a set of Ironmasters if you are not 100% sure you are going to continue lifting in the future. Ironmaster do sell the 45lb pair without the stand, this could be a good idea to start there and add as you grow.

The dumbbells’ weight increases in 2.5lb increments,  presenting you with around 30 different weight settings, making them one of the most versatile pairs of adjustable dumbbells on the market. And if you think how many pairs of fixed dumbbells you would need to have something similar in your home gym, you really do start to see why the adjustable dumbbell is such a great space saving bit of kit.

Add On’s ( expansion kits)

What a lot of experienced weightlifters are going to like about the Ironmaster adjustable dumbbells are the options of the add-on kits and let’s say they’re pretty big, the first set increases the weight of each dumbbell up to 120lb and the second to 165lb, I’m sure this will cover just about any lifter out there.

Each set includes two extra length locking pins, as the standard ones you receive with the dumbbells are not long enough when the extra weight is added to both ends.

Ease of Adjustment

Unlike the dial system of the Bowflex or the twist locks of the Core Fitness adjustable dumbbells, you will find the Ironmasters take considerably more time to adjust. Even the Powerblock push and pull pin system is a much quicker design to adjust compared with the Ironmasters’ Quick Lock system. You’re looking at around 20 seconds to change each dumbbell, 40 secs in total between sets.

Depending on how you’re training the short time taken removing /adding plates for most, shouldn’t be a deal breaker but I think it’s the only con you will find with this pair of dumbbells. The locking pins are knurled on each end helping with grip especially useful if your hands are sweaty, another nice little design feature from Ironmaster.

The steel locking pins lock extremely tight with no rattles and give a nice solid feel. You slide the lock pin through the dumbbell until it reaches the stopping point and then with a simple half twist of the wrist the pins lock in place, couple this with their compact design and you have an adjustable dumbbell that feels solid and not too far from the natural feel of a fixed weight dumbbell.

Durability & Build Quality

Ironmaster pride themselves on the quality of their products and their adjustable dumbbells certainly reflect this. Ironmaster have been producing some of the most sought after and respected home gym equipment since 1978. There’s no need worry about experience here, with 40’s yrs worth of it, Ironmaster knows what they’re doing when it comes to high-quality home gym equipment.

The weight plates are square and have indented grooves that attach together with 1″ sized hole diameters, the plates are machined to fit tight to prevent any rattle. The plates are nicely cast and have the Ironmaster name and logo cast into them, looks quite cool as well as their weight in lbs and kgs. A square plate will also stop any rolling dumbbells.

The handles’ diameter is 1.25″ with a medium knurling, coated in chrome, some of you will prefer 1.5″ handle diameter for heavy presses but 1.25″ works and you shouldn’t get any problems, there has been no mention of the 1.25″ handle causing any issues in the many reviews I have read.

Unlike the PVC coated iron plates on some of the other adjustable pairs I have reviewed,  the Ironmasters can be dropped, you don’t have to worry about flimsy plastic parts with these dumbbells you can drop from height when training to failure and not worry about harming the dumbbells.

They’re built to last a lifetime, an old-school/new-school dumbbell, with Ironmasters patented Quick-Lock design feature aiming for speedy adjustment times. And when they say a lifetime, they mean it! The Ironmaster dumbbells come with a lifetime warranty. Shows this company has a lot of faith in its fitness products.

The handles on their own weigh 5lb and feel solid, add the pins weighing 2.5lb each and you get a total empty handle of 10lb, a good weight feeling heavy duty and quality.

The Stand

Designed to take up minimal space the dumbbell stand is quick to assemble and is a worthwhile bit of kit to purchase alongside the dumbbells. Complete with three shelves there’s easily enough room to accommodate the addition weights from the add-on packs.

There is space on top of the stand to keep dumbbells locked and ready for your next session. Each shelf is coated with a rubber layer to help prevent the stand from rust.

    Hello Jay.D, Ironmaster Quick-Lock dumbbells looks great, I would like to ask about the hand gripped position. What If my hand is wet during practicing session, the Ironmaster still have some friction?

    I like the feature of the dumbbells’ weight increasing and the Ironmasters’ Quick Lock system. By the way, the stand is included with Ironmaster dumbbells as a complete set?

    • Jay.D

      Hi, the dumbbells grip has medium knurling this really helps with any slippage issues! But if problems persist with slippage, its best to either get hold of some chalk or invest in a pair of gloves.

      Yes you can buy the Ironmaster dumbbells with or without the stand 🙂

      Thanks for the comment

    Hi Jay, thanks for this review.
    I am just starting to get into weights so was interested in your point of view. Where I live space is a massive luxury so these seem like a good option as they are small but easily adjustable as I get better at lifting.
    Do you think these are good for someone who is starting out or is there something better that you would recommend?

    I heard Iromaster before it has a lot of gym products and even my friends bought a couple of gym equipment from this company. Handles weigh around 5 and it is quite good however how is the hold of it? Some handles are just too tough and it makes it hard to have a good grip.

    • Jay.D

      Personally I’ve had no issues with the grips knurling, it’s a medium knurling and shouldn’t prove problematic for most people. If you have delicate hands or want to avoid calluses try and get hold of some lifting gloves 🙂

    I would be buying these as a beginner lifter. I think this would make a great choice because of the warranty and the durability of the set. I do have a question. I see they go up to 75 lbs. What is the smallest weight you can start them out at? As a beginner, and a female, I know that 75 lbs would be too heavy for me.

    • Jay.D


      Before we can talk about the lowest weight settings, you need to remember the handles on their own weigh 5lb and the pins weigh 2.5lb each, the lowest weight you can add each side of the dumbbell is 2.5lbs. The weight of the handle with the pin is 7.5lb add the 2.5lb each side of the dumbbell and you get a total of 12.5lb for each dumbbell.

      Obviously, if you are not taking the handle weight into consideration then the lowest weight is 5lb, you can then increase the weight in 2.5lb increments as your strength increases. Hope this answered your question, thanks for dropping by.
