    Unparalleled Quality and Realistic Feeling Adjustable DumbbellsMany adjustable dumbbells suffer from the same set of problems and annoyances. They are cheaply made causing them to break or become non-functioning after a short period of time. Not only is this expensive, it can also be extremely dangerous. People have reported competitors products releasing plates from the dumbbell and causing significant injuries. With Ironmaster, you do not have to worry about this. Our products are guaranteed for life with a no-frills lifetime warranty. Another common complaint of competitor products is that the dumbbells do not feel like a real dumbbell. Our adjustable dumbbells look, feel, and function just like real dumbbells. They are solid and ready to go containing no plastic or fragile components.

    Long Term Review
    Van (CA) | April 6th, 2022
    I've been using these, along with the additional weight kit, for over 15 years and they are still working great. I mostly only use them for heavy sets. I've supplemented them with quick select dumbbells for speed. If I could only have one set, it would be these.
    Almost perfect
    M Pen (FL) | April 4th, 2022
    Great feeling DBs! Knurling is fantastic, feel is that of a true DB, and the ability to go up to 165lbs is absolutely insane.
    The stand isnt the best a little tight when changing weights, much easier to do that on the floor, but then you have weight plates all over the place and that alone can be a hazard. Telling how much weight is on there is not the easiest, but doable.
    Pros: Durability, feel, knurling, and overall weight capacity. Solid build and warranty.
    Cons: Availability, seeing how much weight is loaded, and adding/removing weight plates when in a rush.

    Overall i prefer these over Powerblocks because I need more weight and enjoy the build of these with a real knurled handle. 4.3/5 stars

    My hybrid set up
    Josh G (Ontario Canada) | March 6th, 2022
    When I see criticisms of Ironmaster dumbbells, it's usually around how "long" it takes to switch weights.

    First of all, with a little practice, it doesn't take long at all. I can always change my weights during my rest period.

    The other issue you might have is a workout partner, especially one who isn't as strong as you. For me, this is my wife.

    So here's what I did...

    I have a dumbbell set from 5-50lbs. Why? Lower weights are cheaper and take up less room, my wife rarely goes above 50lbs for anything, if her and I are working out together it's in the lower weights where we'll "clash," and if I need to switch weights really fast it's likely to be the lower weights.

    I use the Ironmasters for anything over 50 lbs. I have the heavy handle set (highly recommend) which brings this set up to 90 lbs. I'll probably buy the next weight upgrade in the next year or so. If bought separately, these dumbbells would get expensive and take up a ton of room.

    And this works because my wife and I aren't sharing anything over 50, and I rarely need to drop or add weight quickly when I get into this range.


    1. The time it takes to change weights is exaggerated. The slight increase in time is 100% the massive increase in quality and feel.

    2. Consider a hybrid approach like mine if you want the best of both worlds.
    Fantastic product, customer service and shipping
    Don Schoppe (North Carolina) | February 18th, 2022
    I just received the QLDB 5-75 lb set and stand. The handles, stand, and plates were packed very well and arrived in pristine condition. The stand assembled easily, looks great, and is compact, taking up less floor space than the old 5-50 lb power blocks and stand that this QLDB set is replacing. I also own an IM1000 machine with accessories that has served me well for many years. I recently added the IM2000 bar hooks and safety spotter arms, adding free-bar capability to my IM1000 machine. It’s great that Ironmaster strives to maintain compatibility with legacy products when possible. The quality, fit and finish of these QLDBs and my other Ironmaster equipment is fantastic. I just ordered the heavy handle kit for the QLDBs to make them as compact as possible for a given weight. Once available I will purchase the 120 lb add-on kit for a total QLDB capacity of 135 lbs. Realistically this is more weight than I’ll likely ever need, but one can hope. Hats off to you ridiculously strong guys and gals that enjoy working out with the 160 lb add-on kit!
    Note From Store Owner: Hats off to you, Don, thank you for your time and review!
    Worth the money
    Nicolas (Tennessee) | February 17th, 2022
    Solid construction. Simple rugged design. No weird rubber coating to wear off. Grip has good traction that isn’t too aggressive. Now to figure out which of my kids gets to inherit these as they’re probably going to outlast me.

    Joe Hoover (AZ) | December 16th, 2021
    It has been 14 years and still nobody makes a set as good as these and especially one that goes to 160lbs! I love my set and am getting the heavy handle kit and maybe the kettlebell next.
    I do wish they were US made though.
    Note From Store Owner: We're happy to hear your enthusiasm, thank you for sharing your comments. We are proud to be a family founded/owned US SMB, and while we do manufacture overseas this allows us to provide a more affordable but still high-quality product that more Americans will have access to -- all designed right here in the great USA.
    Home Gym Must Have
    Sydney (Erie, Pennsylvania) | December 7th, 2021
    My husband and I recently purchased these for our home gym (after a long, long lottery process) and we love them! Adjusting the weights takes a minute to get used to but once you do it's smooth sailing. The quality is great and shipping was very fast. Worth the wait of the lottery!
    The Best Adjustable Dumbbells for a Home Gym
    Alex (Arlington Heights, IL) | November 5th, 2021
    The Ironmaster Quick-Lock Adjustable Dumbbell System 75 lb Set is a home gym essential, if you can afford it. As a powerlifter, these help to do so many accessory lifts without having to leave the house. While you can't really superset them compared to other adjustable dumbbells, these are easily a higher quality dumbbell compared to the competition. These can be dropped, has the feeling of a traditional dumbbell with space savings, and can go really heavy.

    To have that convenience in my own house is amazing. I will want to try and purchase the 120 upgrade kit when I can because it is needed. The fact these have an expansion kit to 165 pounds is crazy. No other adjustable dumbbell can compare to Ironmaster for how easy and sturdy they are to use. I would highly recommend these to anyone that does not need to quickly super set and has the money to spend on high quality and durable adjustable dumbbells.
    Perfect edition to a home gym.
    Humberto (Pembroke Pines, Fl) | November 1st, 2021
    I recently purchased the 75 lb. set for my home gym. It took a bit to get used to switching the weights. But once I got the hang of it's not bad. I like how sturdy they are and the wide range of weight. I've had a few other adjustable dumbbells that are easier to swap the weights. This set has the most weight and can be dropped reasonably. The handle with the knurling feels just like weight's at the gym.

    Number one for a reason
    Kent (MO) | October 3rd, 2021
    These are Iron Master's number one products for a reason. Outstanding build quality, durable, and the weight is very accurate! I hated the lottery process but this was worth the headache, in many ways this is the best gym product ever. They feel way better than traditional commercial dumbells and once you get the hang of it you can change the weight pretty quickly. A must buy for any home gym owner!

    Best DB set!!
    Jesus Noriega (Henderson, NV) | September 30th, 2021
    As soon as I ordered this set, I couldn’t wait to receive them. I love using this equipment in my home gym and it is so versatile and compact! I can’t wait to order the expansion to 125lb and the fat grip. Definitely a lifetime product! And the changes come pretty fast. I wish iron master would create a chart for easy set ups for weight.

    These are very good quality. I was thoroughly impressed. Even the shelf was better than I thought it would be. The plates were all individually wrapped which just shows the care and quality put into these. Will be getting the add on plates once I can win the chance to.

    Quick-Lock Adjustable Dumbbell System 75 lb Set
    Andre Adams | August 23rd, 2021
    After searching the market for heavy duty adjustable dumbbells for many months, a friend of mine introduced me to Ironmaster. In the past I was unimpressed with the adjustable plastic dumbbells on the market. As an IFBB Pro bodybuilder and trainer they just didn’t hold up and we’re not heavy enough to get the job done.
    Ironmaster was a breeze to work with having awesome customer service. Once I received the quicklock dumbbells I was very impressed with the quality of the design and the feeling of a real steel dumbbell. In fact, I immediately upgraded from the 75 lb kit to the 135 lb heavy handle expansion kit.
    The quicklock mechanism is easy to adjust and makes them the most robust adjustable dumbbell on the market.

    Glad I waited
    David | August 10th, 2021
    I've had my dumbbells for about 4 months now and I could not be happier with them! I had to wait about 6 months to finally get picked out of the lottery but these dumbbells are definitely worth every bit of the wait. If you're getting impatient work on other aspects of strength and mobility as you wait for these, you will not regret it. They are solid and everyone who's tried them is impressed by how close they are to regular dumbbells as far as feel. I will definitely be purchasing the add on kit in the future.

    Awesome Dumbbells, but the Stand Needs to be Wider
    Joshua Z. Sison (2315 Bennington Drive) | July 13th, 2021
    Best investment I made from 3 years ago and still is to this day. They are durable and reduce space in my garage. I notice that I and a lot of my clients prefer to place the dumbells back "the wrong way" after a set since it's the wide part of the stand reduces moment arm, especially when the dumbells are starting to get longer as more weight is added. It would be great if they made the stand wider. I'm also missing a pair of 5lbs for my Add On Kit 120lb when it first arrived at my place and I appreciate it if they could send me a pair of 5lbs for it. If I could take off half a star, I would. Overall it's a good product for various strengthening activities. They just need to make the stand wider

    Best adjustable dumbbells
    William (Ca) | July 9th, 2021
    By far these are the best adjustable dumbbells. These are not like the screw spin off ones where you have the spikes hitting you in the leg And you don’t even have to keep twisting them to take the weights off. It’s just an easy 3/4 turn and pull the whole screw out and adjust within Seconds its great for not having to wait too long between sets if you want to drop weight or move up in weight. If you’re looking to buy Dumbbells this is the best way. You don’t have to buy each individual pairs and you have an adjustable pair with a very sturdy stand that goes 5 pounds to 75 pounds. I also bought the add-on kit to where you can make each individual dumbbell 120 lbs each. I love this set and I’ve almost bought everything this company makes. Very high-quality and engineered to perfection

    I've had my dumbbells for a little over a year now and have definitely put them through their paces. These dumbbells are a little on the expensive side, but are of amazing quality and still cheaper than your average fixed dumbbell set of equivalent weight. Most versatile I've seen. You won't find anything else out there that's comparable. All metal construction, iron plates, and solid at any weight configuration. You will not be disappointed. Customer service is really great too at 4/5 stars based on personal experience which I'll cover in the IM2000 review. All in all, very pleased with my dumbbells.

    Matt | May 19th, 2021
    WOW! Thank you and Ironmaster for making the best adjustable and most versatile dumbbells on the market today. The heavy handle kit (HHK) makes your dumbbells more centered and stable than all the gym quality dumbbells I have ever used. I cant believe they are adjustable. They feel so good in my hands. I can now make a dumbbell go up in 2.5 lb increments from 20 to 180 lbs. That is exactly 13,000 lbs in fixed dumbbells not counting the 5 to 17.5 lb weight changes available if need be by removing the HHK. A pair of 180 lb dumbbells cost more than $2300. All you kits combined are less than $1700 and that includes the stand! WOW! An average wage earner can afford your dumbbells. Thank you, Ironmaster, for making this possible. Ref, thank you also for selling me only the extra extra long screws when I had extra plates. No company beats Ironmaster for such a fantastic product and outstanding customer service. WOW! Very Truly Recommend Ironmaster:?? -David Johnson

    Charles | May 2nd, 2021
    Best thing ever. Had the original QLDB from about 18 years ago but sold them when I moved. Waited almost a year for the new ones once Covid hit and added the heavy handles and 120lb add on kit. Could not be happier and well worth the wait. Quality and functionality over the original is unbelievable. Same goes for the super bench vs the original bench I had. Great job Ironmaster and thank you for supporting the Vets!
    Quick-Lock Adjustable Dumbbell System 75 lb SetReview
    Bruce (Meridian, ID) | February 16th, 2021
    Prior to COVID, like many, I worked out in a commercial gym. I had some basic equipment in my garage to get a supplemental workout in here and there. This equipment included a set of PowerBlock Pro-Rexan dumbbells. I had them for over 20 years; they held up very well and served their purpose nicely. Once I canceled my gym membership and built out a nice gym for myself in the garage that I now use full time, I found myself avoiding the PowerBlock dumbbells. When using them occasionally, I could live with the rattling, the awkward block shape, and the non-traditional dumbbell feel. I'd skip certain exercises because I didn't like how the PowerBlock dumbbells felt and I'd simply do a different exercise. However, once my garage became my primary, and only, workout space, I wanted a set of adjustable dumbbells that perform and feel like real dumbbells ... and could be used for every exercise I want to use them for. The Ironmaster QLDB are the perfect solution! No foam handles, no plastic parts, no rattling, no awkward feel, no odd skips in weight, no worries about dropping them. The Ironmaster QLDB are built tough! The all iron construction feels durable. The knurled grip feels great in hand. The plates fit together nicely and they are tightly secured to the handle; no annoying rattling. The quick lock system is quick and easy to use. It isn't as fast as some of the other systems out there, but it's far superior to spin lock systems. If speed of changing weight is your top priority in a dumbbell, then you will find some other options more appealing. If quality, feel, practicality, and customer support are important to you; these are the best option ... HANDS DOWN! I absolutely do not regret selling my PowerBlock set and replacing them with the Ironmaster QLDB. I find myself incorporating dumbbells into my workouts far more than I ever have in the past. I had to wait 5 months before I could purchase a set of 75lb Ironmaster QLDB, but it was worth the wait. I'm not sure how long it will take before I can get my hands on the 120lb upgrade kit, but I don't mind waiting because I know I'm going to be 100% satisfied with them once I finally have them.

    On another note; I've read some reviews where people aren't pleased with the quality of the stand. I have to say that I find this stand to be better than the PowerBlock stand. The PowerBlock stand had some wobble to it, but the IronMaster stand feels solid and stable to me; no rocking whatsoever. I agree that the top could be a little wider to make setting heavy weight down a bit easier, but it's not a deal breaker by any means.

    Otto (Flushing, NY) | February 10th, 2021
    amazing customer service = answered all of my questions. continued to update me when things got delayed due to the Pandemic. I wound up getting the quick lock 75, heavy hand upgrade and the 120 add on kit. one Kettle Bell. the versatility of being able to use on the Kettle Bell as well as Dumbbells is imo ingenious. I've dropped the 135 as a failed set and the dumbbell is fine. have you seen the videos where they drop it down a flight of stairs? very sturdy. one small issue, I wish the stand was wider. When I put the dumbbells back up you need to be pretty perfect on dropping them in or you'll scratch the edges. when you have lighter dumbbells it's not an issue but say for example you're trying to put the 100's back on the stand - I've scratched a lot now as it's millimeters of clearance. other than that, this is used every day I work out in some capacity. I highly recommend this product and would like to thank the customer support for being so amazing.

    Donald (Surprise, AZ) | February 3rd, 2021
    Wow just wow! I had the powerblock U90 series and thought that they were nice but Ironmaster blows them out of the water. The powerblocks seemed fragile and would nick and cut if dropped. I had to be extra careful when using them not to push it to failure because of fear of them breaking. Not with Ironmaster. These are the closest adjustable dumbbells that feel just like a commercial set. Tough as nails!

    Benjamin (Fort Belvoir, VA) | January 18th, 2021
    Wow! These things are truly amazing! The weights take less than 90 seconds to remove a swap plates to change the weight. Obviously they get smaller the less weight on them so they perform like real dumbbells. The locking pins are super quality. I've been wanting a set like this for years and glad I finally got these. If you want to operate them as a 10lb weight with no plates added you have to turn both locking screws carefully at the same time to secure. Otherwise, this set is amazing.

    I have been attempting to purchase your 75 pound adjustable dumbbell set for nine months, since March, 2020. Covid and short supplies interfered. I was finally successful and my dumbbells arrived today. Wow, were they worth the wait!! The dumbbells are solid, have great knurling and feel really good in the hands. The dumbbell stand is also easily assembled and very sturdy. I have purchased from Ironmaster in the past (kettlebell, bench) and will continue to do so. Great quality products, well-packaged, superb customer service.

    WESLEY (Fort Mill, SC) | August 18th, 2020
    Just received my 75lb dumbbells and stand. While I have only put a single work out on them, I am very impressed with the quick lock mechanism. It is extremely easy to unlock, change weight and lock them back into place. I was expecting to have to perform a lot of cranking/spinning on these for each weight change. The speed lock is a really ingenious design and has a solid lock to it.

    I have a set of the small power block dumbbells and I found found I need to spend a bit of time to select the right pin holes for that dumbbell system...and it rattles quite a bit. I prefer the Iron Master design already. Solid locking mechanism, no rattles and closer to a standard dumbbell shape...making it more versatile than the power block approach.

    Very happy with this product! An excellent addition to my home gym.

    Over 6 years ago, 2014, I bought these ironmaster dumbbells and stand... back when ya Had to pay for shipping .... and Ive used them so much it has been totally worth it. Some of the paint has slightly worn off around a few edges, but they work and feel just like new. Rock solid and sturdy, not once have they ever come undone while using them. I highly recommend the add on for fat grips. I got the 1.5in grips which helps distribute the weight more evenly across your hand when you getting into heavier training. I also have the 120lb add on kit, works great.
    The stand is very compact, but so needed. Getting the 120lb weights onto each dumbbell requires adjusting the dumbell position... If the stand were any smaller it would be too small, but it is super solid and holds all the weight just fine. Very convenient for small apartments.
    I do wish the stand came with wheels. Best dumbbells ever.
