Easy to change weights
Changing the weight is so simple it’s possible with one hand only. All it requires is turning the locking mechanism 90 degrees and the locking pin comes loose. Changing weights requires less than 15 seconds.
Easy to expand weights
The dumbbell set offers a weight range from 2.2 – 20.4kg. However the handles and locking screws can carry as much as 34kg (75lb) using additional weight plates. When adding any of the add-on kits, the dumbbell can be extended to hold up to 74kg (165lb) per dumbbell. The weight plates required are compatible with the Kettlebell, EZ Curlbar or Straight bar.
Feel like traditional Dumbbells
The Ironmaster Dumbbell feels like a one-piece dumbbell due to its advanced locking mechanism. The compact design makes the dumbbell no limitations in gripping possibilities.
Save spacing
Due to the convenience in changing weights and high-end compact design, the Ironmaster Dumbbell replaces a full range of solid dumbbells with various weights. Hence, saving space and budget.
Unbeatable quality made from heavy duty steel
The Ironmaster dumbbells are made of the best steel out there. The advanced and patented locking mechanism prevents any rattling or loosening. Chrome plated steel handles with diamond knurled grips offers the ultimate grip. You won’t need to think about anything except lifting. The dumbbells are so strong, they sustain even when being dropped on the floor after sets.

Great dumbbells
I've tried a lot of different adjustable dumbbells. Some have been plastic-y, awkward, cagey, have things to rotate or pins to set to lock the plates into stands.
And the IM dumbbells are the best.
It feels like a real dumbbell, solid construction, well balanced, and the plate changing mechanism is fast and makes sense. These are high quality, long lasting, professional dumbbells. Highly recommend.

45 lb Quicklock Review
These are durable and easy to put together. The quick lock system really does cut down on time. They’re faster to switch weight than “smart” adjustable dumbbells I’ve bought in the past. They’re easy to grip with the knurling and overall maintain a normal “dumbbell feel.” They’re considerably less bulky than competitors, which is nice.

Best Dumbbells For Getting Strong!
Great product, from a great company. I had to wait for them to come back in stock, since they're so popular, they were definitely worth the wait. I can't imagine them ever breaking without bad intentions and tools that i don't have or know how to use. Their customer service is great as well, in my experience they go out of their way to satisfy customers. If you hope to one day lift pretty heavy with dumbbells, there are none that come close to these.

Fantastic dumbbells
I have used Bowflex dumbbells for a couple of years and have been underwhelmed. They are bulky and fragile, having broken pieces off a couple of times without serious abuse. In a search of more durable dumbbells I came upon these and several other brands. What convinced me to try Ironmaster was the fact that everything was steel, no plastic parts. These do not disappoint. They are sturdy, compact, and feel great in the hand. I heartily recommend these dumbbells and am sure they will last a lot longer than me!

Great Dumbells!
I've been wanting a pair of these for 20 years and finally got them in 2022... man I wish I would have had these sooner! They are fantastic, heavy duty and of great quality. I really like working out with these. I can't wait to get an extra set of handles so I can have two different sets at a time.

Awesome Dumbbells
There were out of stock a couple of times when I tried to order them, but it was well worth the wait. They are solid, great quality, and very easy to change weights. I also like the fact that I can get an expansion kit, if I want one. Amazing stuff and they shipped out the next day!

Your grandkids will use these
Solid, well made, sit comfortably on the knees between sets of chest presses, and perfect balance. I added the heavy handle set which makes these feel just like the typical gym heavy bells. Once you get used to the "plate math" (handles are 5, quick-locks are 2.5 apiece, heavy handles are 15 for 25lb base weight) it is easy to calculate weights and change them. Less than 60 seconds for both bells.
I also bought the 75lb add-on kit, which with the heavy handles makes these go from 20 to 90lbs. And of course I got the 2.5 micro plates for those plateaus.
Buy them. You won't be disappointed. Neither will your kids, or their kids.

Dumbell Set
These dumbbells are rock solid with a very old school feel to them along with being a perfect size/balance for most all exercises. Taking an extra couple of seconds to reload the poundage is more than worth using the more popular twist handle adjustables given how much plastic in the mechanisms. I mean I'm not like throwing weights around on the regular but eventually if you are really working hard enough one will crash to the floor eventually and these will NOT break (maybe the floor...haha). Willing to take the chance with another $600 plus set...not for me. Also, luv the expansion options what else could you ask for..??

Simply love these dumbbells. They have a great feel to them. The quick-lock handles work very well, securing the plates tightly, resulting in the feel of a sold block of steel without any parts rattling or moving.

Glad I did the research
I’m extremely pleased with my Ironmaster purchase, including the ordering process and prompt subsequent customer service to track my order. These replace a set of far lesser 45 ld weights. I considered several alternatives and settled on these thanks to positive reviews and a desire for an adjustable dumbbell that performed during the work out like a non adjustable weight. This is definitely the ticket. Getting the hang of quickly changing the weights happened after a couple of workouts and I now enjoy a set of 75 lb adjustable dumb bells that work like a full set of non adjustable weights. I don’t believe there is a better system on the market.

My first purchase from Ironmaster
I was in need of a quality set of adjustable dumbbells to start my home gym. I spent some time researching on-line and watched tonnes of YouTube video reviews. Finally, I decided on these dumbbells. They were like Unicorns when they came in stock and when time and money intersected I ordered them to be shipped to Canada. I am so pleased I took the decision. They arrived at my door with great care and were packaged expertly. I've used them for about a month and they are superior quality, well made and will be a part of my fitness journey for a long time. Thanks Ironmaster, I'll be ordering more stuff again.

Great quality!
The quality of these dumbbells are great. Very solid, and I like that there are no plastic parts. I moved over from Powerblocks, which served me well for a really long time, but the plastic parts begin to show wear and tear. Switching the weights is noticeably slower, but I would gladly trade the speed for the versatility and durability! So ultimately it depends on what you prioritize in your dumbbells, but these are a pretty solid choice.

I've used the rest, and these are the best. Beautiful dumbbells with the look and feel of real dumbbells. Quality, heavy-duty build. While not as fast as competitors for weight changes, they are still quite fast. Like I said, I've used them all, and these are my favorite, hands down. If you can get a pair of these for your home gym, do it. Also less expensive than competitors in the high-end adjustable dumbbell market.

Quick-Lock Adjustable Dumbbell System 45 lb Set
An incredible product. Extremely well-made, weight feels even in your hand and handle has good knurl. Feels like a normal dumbbell with VERY minimal shifting of plates during reps.
Weight changes are a little bit slower than some of the other players in this space (Bowflex, Powerblocka), but I think it is worth it for the quality of construction. Also a huge bonus that you can easily buy additional weight of you ever want to.
Lastly, these dumbbells pair perfectly with the kettlebell handles and other bars (straight bar/EZ bar) to create a great starting point for a home gym.
A really well-made and adaptable product. Huge fan.

Quick-Lock Adjustable Dumbbell System 45 lb Set
Impressive!
These adjustable dumbbells have been recommended to me so many times that I decided it was time to get a pair. This is easily one of the best home gym products I've ever purchased. These dumbbells are so sturdy and incredibly well-made, and take up a fraction of the space a traditional rack would take up. The swapping between weights takes a bit of getting used to but once you get it down it's quite quick. For the price, these are a great deal. You can tell they're basically going to last forever (with some basic wear and tear).
Both myself and my husband are very pleased, and both of us use them. Bravo!

the dumbells are very sturdy no plastic parts. these will be the dumbells i will stick with forever. and ive had other adjustable dumbells before. you will not regret it

Quick-Lock Adjustable Dumbbell System 45 lb Set
They're priceless to me.
This truly exceeded my expectations and well worth the expense to me. The quality is outstanding and time for plate changes just a brief pause in whatever you're doing with them. I can't imagine anyone with a drive to exercise having an issue with a quarter turn and quick switch to have something durable of quality that can't fail or wear out over time ?
As a followup to the above... I've recently added Ironmaster's 1.5" fat grip adapters to the set and I love them. I also added Ironmaster's quick-lock Kettlebell and loving it too : )

I had originally bought the 75 lb. Quick Lock adjustable dumbbell set. I bought 2 additional pairs of handles. The 3 pairs of handles fit perfectly on top of my Ironmaster cabinet placed vertically (screw lying on the cabinet) saving me space. It was a worthwhile investment as it now allows me to do my workout faster without having to waste time changing plates. It also increases my energy expenditure as I don't have to slow down between exercises to change the weight of dumbbells. I also bought additional 2.5 lb. and 5 lb. plates to have the ability to load the dumbbells to the desired weight prior to starting my workout. (Customer service superstar) did a great job of accommodating my needs.
