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 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 adjustable 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.

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.

To Sum Up

A solid pair of dumbbells from Ironmaster, if you want the feel of a fixed dumbbell but like the space saving design adjustable dumbbells offer, then the Ironmaster dumbbells are about as close as you are going to get.

The pair are built to last and will take just about all you can throw at them, with the additional weight add-ons and a lifetime warranty, you shouldn’t have to purchase another set of dumbbells in your lifetime.

Great design, fantastic weight range and an awesome stand to keep everything together, a very well thought out pair of dumbbells from the king of home gym equipment.
