    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.

    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.

    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.

    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

    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!

    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.

    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.

    Absolutely love these things. I have the Power Block Elites as well, and these feel 100x better. I even like them better than my Goodlife gym dumb bells. They look way better in real life than in pictures. Easily Worth the money even if it costed more. Definitely get the 120 set for easier change out(especially if you can lift over 80 easily).

    I live In Canada so it was a pain to get these. Especially during the pandemic. I did a ton of research, and bought these things without ever touching them. Pretty sure its the best investment I've made. I'm very glad I spent the time and money to get these, they make me excited to work out and it has been keeping me in routine 5 days a week. And they are just a beauty to look at, seriously. Quality is easily 10/10.

    these dumbbells are as rock solid as one single piece of steel. They tighten so nicely I can't even believe it. I knew these things were going to be absolutely unreal before I purchased them. Believe it or not, they are actually even better than my expectation. So quick and easy to adjust. I also have the 120 and 165 add-on kits and it takes up so little space it's funny.

    Hands down the best adjustable dumbbell I've come across for a few reasons.
    1) They feel like a pre-fab dumbbell (I like the powerblocks and bowflex, but both of them are a little awkward between the bowflex having gaps between plates and the powerblock putting your hand in a cage)
    2) They extend up to 165lbs
    3) There is NO wiggle when locked into place
    4) The engineering of having the plates fit into each other before the lock screw is in place makes it super quick and easy to shift the weight around

    All-in-all to say I'm impressed by these things would be an understatement. I cannot recommend them highly enough!

    Best adjustable dumbbells that I have ever used. They lock up real solid with absolutely no rattle. I use the time changing the weight as a rest interval and then jump right into my next set or exercise. I recommend purchasing the 120 lbs add on kit since the 22.5 lb weights are much quicker to add than multiple 5 lb plate. Combine these with the Ironmaster Quick-Lock Adjustable Kettlebells and a bench and that is all you need for a home gym.

    These dumbbells are excellent quality and design. They are the correct size handle, excellent grip, and it is easy to change weights. I have lifted for several years and had a large set of dumbbells in my first garage gym. In my new garage gym, I wanted to go with adjustable dumbbells for space, but I was concerned about quality, ease of use, and comfort. These dumbbells exceeded my expectations and feel excellent for performing all exercises. Some adjustable weights are too large (long handles) that are awkward and do not feel like dumbbells. Also, unlike other adjustable dumbbells, they are comfortable while resting on your legs (setup) for doing bench press, shoulder, press, seated curls, etc. The included stand is perfect, and I will be purchasing the curl bar when back in stock. I am sure like you, I conduct a lot of research before buying anything, in particular when it is expensive. These dumbbells are worth the cost, and you get what you pay for. I highly recommend. I hope this review is helpful.

    I bought this set five years ago. They are every bit as they say they are. These t dumbbells are solid, once you lock them there is no clunking, they are solydly built and feel just like the gym dumbells. I carried them in my truck (I'm a trucker) but now as I'm building my home gym, with everything Ironmaster, IM2000, super bench pro, attachments, 410 lb plate set etc. I have it in my garage and finally built the stand that came with it. That stand is solid as a rock and can hold much more than this set of dumbells especially where you have space constraints. The competition doesn't even compare to Ironmaster. Need a solid set that will last you a lifetime? Go get Ironmaster.
    Their customer service is bar non.

    These are amazing. Totally surpassed my expectations for adjustable DBs and getting the KB adjustables gives me more flexibility in my floor program. I am ditching my gym membership because of this set. Now I can do spin cardio and weight training in the comfort of my own home and the convenience factor is huge. I will be purchasing add-ons and additional adjustable DBs so I can setup even more variety in my workout.

    Instructions are clear for usage and assembly of the dumbbell rack was a snap! Took about 1 hour total to unbox, assemble, store, and test the equipment.

    Wish Peloton would up its game on its bike (I own one and use it quite regularly - Hollywood_Porky is my username) - maybe Ironmaster can teach them a thing or two about product quality.

    Justin | August 18th, 2019
    I spent about a year reading reviews and watching YouTube videos before finally buying the adjustable Ironmaster dumbbell set. My biggest challenge was justifying spending about double the price of the Bowflex or Powerblock adjustable dumbbells. At the end of the day all the reviews showed that those brands had a lot of plastic parts which easily broke, compared to the Ironmaster which are made 100pct steel.

    Over a year in and these weights really dont take that long to add/remove weights. You need a mini break between sets anyway so its not as annoying as I thought itd be.

    Secondly, the quality of what youre buying is really why youre paying more than Bowflex and Powerblock. The locking system works very smoothly, and doesnt appear as though itd have any issues in the future. Additionally, I have these weights in my basement where the humidity is higher than average, and theres absolutely not sign of rust, so it appears as though the quality of the steel used to make them is pretty high.

    Overall these weights are definitely worth the additional money over the competition. In the long run, youll probably spend less money buying one good quality dumbbell set instead of buying several cheap pairs.

    Thanks Ironmaster and I hope anyone reading this finds my review helpful.

    It was a great experience. The lock and unlock process was so smooth. It didnt take much space in our little home gym. The grip was amazing. The experience never felt different from any commercial gym dumbbells that I tried before.

    All in all we loved it. Thank you so much for making such a great product and thank you for the quick delivery.

    I just opened my packages and I have to say these dumbbells exceeded my expectations. The quality is better than anything I have ever seen. Right after my purchase I felt a little buyers remorse because they are a little pricey. But after putting everything together and getting them in hand I have to say any remorse I had disappeared. I cant stress the quality enough; and if that wasnt enough, these dumbbells come with a lifetime warranty!!

    On another positive. The Ironmaster customer service is INCREDIBLE. So after opening all my packages and putting everything together I noticed that I was missing one five pound plate. I immediately called customer service and spoke with Matt. Just like that I had the five pound plate on its way. Now everyone at one point or another will make a mistake, thats not uncommon. What is uncommon is truly great customer service that stands by their obligation of customer satisfaction. Ironmaster youve gained a customer for life!!!

    Fantastic set! I was looking at some of the competitors such as powerblock and bowflex- didn't like how bulky they were. I was a little concerned about the ironmaster's set as well. When I received them I was pleasantly surprised. This feel just like a standard dumbbell. Not super awkward and well balanced. I loaded them up and they felt solid! Now just need to get the 120lb add on kit!!!
    I spent hours researching all the adjustable sets out there....Im going to save you time...just get these--currently there is no comparison.
