    The Ironmaster 75 LB Quick-Lock Dumbbell Set is one of our flagship products and a customer favorite for people looking for premium quality adjustable dumbbells. Our latest generation of this product includes our patented quick lock technology allowing you to adjust the weight of each dumbbell from 5 to 75lbs in 2.5 LB increments in less than 15 seconds! The system also includes the dumbbell stand.

    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. More information about this product is available below in the product details section.

    Features of the 75lb Ironmaster Adjustable Dumbbells:

    • Quick-Lock handle design lets you add or remove plates with just a partial turn of the locking screws! US Patent 7,182,716
    • Adjust from 5-75 lbs each in 2.5 lb increments in just seconds. (75 lbs each dumbbell = 150 lbs total)
    • Set includes two handles with four locking screws, 24 ea. 5 lb plates and 4 ea. 2.5 lb plates. Handles weigh 5 lbs empty and each locking screw weighs 2.5 lbs so the starting weight is 10 lbs each adjustable dumbbell before plates are added. 65 lbs of plates can be loaded on each handle.

    Worth every penny!
    John (UT) | October 2nd, 2022
    I'm impressed with the solidity of the dumbells even at 120 lbs. I am very grateful for the excellent engineering. They are a TON cheaper than buying heavy dumbells individually and save a TON of space. Switching the weight is like counting how many dollars I have saved with this purchased. Nicely done!

    Quick Lock 75 Lb Adjustable
    Nathan (Maryland) | October 1st, 2022
    I recently bit the bullet and purchased the 75# adjustable dumbbell set. This is my first set of adjustable dumbbells and I did a ton of research. For me, I already had existing smaller dumbbells (in the 10-35# range), so was drawn to Iron Master set for two prime reasons: durability and accommodating heavy loads. Most adjustable dumbbells in this price range have plastic internals for the interlocking mechanisms. While quicker, I expect they are far less durable and most certainly don't advertise that you can drop them; in fact, most tell you not to.

    I've had them now for a few weeks, and though I haven't really pushed it to the limits and dropped them from several feet, they definitely feel durable. So far, so good.

    Granted, I'm only a few weeks in, but so far my impression is that I would recommend them to anyone looking for a rugged, long-lasting dumbbell to add to their home gym.

    Great set!

    Expensive, but worth it. Love the quick adjust and solid feel. The only person unhappy with my purchase was the UPS guy who had to deliver them!

    Larry (Raleigh NC) | September 23rd, 2022
    Back when gyms closed due to Covid, we all scrambled to set up home gyms. New companies sprang up with no track record. The demand for established products like the Ironmaster dumbbells were insane. After about 3 months of trying I finally was able to order. They were everything I assumed. No plastic parts to break and shaped like traditional DBs. They aren't cheap but compared to any other adjustables, they're worth every dime if you want something that will outlive you.
    I'm loving these!
    Aleksandar (Algonquin, IL) | August 22nd, 2022
    After watching and reading tons of reviews I settled with these Ironmaster adjustable dumbbells. I liked Powerblocks as well, but Ironmaster won out for durability incase of drops, and more natural feel. Even as you add plates, they never feel too long or big in relation to a regular dumbbell of the same weight. The other adjustables didn't feel as nice. I also added the heavy handle kit at the same time I bought these and it really gives the handle grip a nicer feel by shortening the handle length. They feel great! I notice no difference between these or regular dumbbells. I'm still working on adjusting the plates faster, but the system works great. No rattles, no plate movement (they fit very tightly), and a natural feel. The stand was smaller than I expected, but it works and the positive is it takes up very little space. Compared to the space a traditional set would occupy, the footprint on these is nothing! You won't regret getting this setup!

    Quick-Lock Adjustable Dumbbell System 75lb Set
    Jason (Brooklyn NY) | August 12th, 2022
    Scarce: Yes, they took forever - to be available. I have been trying to buy these since the Pandemic began. Pricey: Are they? If you buy individual weights, to 75lbs - not really. Quality and Ease of use: Priceless and Spot-On. I would wait again and again for the quality that came with this. Most adjustable weight are flimsy, and “Shakey”, at best; these are SOLID. Highly recommended. Spend the money, this is worth it. I’m waiting on the Add-On, to get to 120lbs.

    Exactly What I wanted
    John (IL) | August 4th, 2022
    I was looking for a high quality and strong adjustable dumbbell set. After using other brands that had plastic components, I was happy to find Ironmaster. Everything is steel and very strong. I like the aesthetics and the design a lot. The only detraction I commonly see is that it takes time to adjust the dumbbells. This doesn’t bother me at all because I lift heavy 90% of the time. I’m in no hurry to change the weight plates for a 70lbs dumbbell press. As soon as the expansion kit is back in stock, I will be purchasing that immediately.
    Amazing, worth every penny
    Jacob Gonzalez (Upland, CA) | August 3rd, 2022
    This is my first time buying gym equipment after deciding to make my own gym at home, these are easily the best investment in my health and fitness journey I have made and will probably ever make. Unfortunately if you are someone who needs to do supersets with different weights, they are not super fast to change weight (considering you have to do all 4 sides) which is not a problem for me at all because I am a slow lifter. Still worth every penny regardless if that's a problem for you or not, I can't give anything less than 5/5

    Rock Solid and Quick Changing
    Sterling Brown (New York) | August 3rd, 2022
    I've been using the Ironmaster adjustable dumbbells for around a month now, and I've been really pleased with their performance. After a lot of research, I decided to get these vs the Nuobells, Powerblocks, Bowflexs, and Pepins. I love how these use absolutely no plastic, and because of the square ends of the weights, they're extremely easy to add or remove weight from with the quick lock system. Even though some competitors can be slightly faster, knowing that these aren't fragile and won't break after being dropped is a huge peace of mind. Swapping weights only takes around 30 seconds, which is the perfect weight time between sets.

    I'll probably be getting the heavy handle kit in a few months, but for my current level, these are a great range of weights.

    Unique design
    Marc Brunton (California) | July 18th, 2022
    If I saw this product in a sporting goods store I might look at it twice. It is a unique design, plates change quickly, the lock bolt is easy to operate. I like the sturdy cabinet that is easy to assemble. The plates are heavy duty, The only real negative is the price. It's a great product but expensive.

    Extremely High Quality Dumbbell Set
    John | July 13th, 2022
    This is a great set of dumbbells, they are secure, heavy duty, easy to adjust, and have the same feel as traditional non-adjustable dumbbells.

    I wish I discovered these before I found the Powerblocks, it is nice to finally have a reliable dumbbell set that does not use fragile and flimsy parts, unlike Powerblock. My set of Powerblocks became unsafe and nearly unusable with all the parts that kept chipping away and snapping off.

    I am absolutely impressed with the high quality of this product, and the way it was so carefully shipped really caught my attention and showed that this is a company that cares and stands behind its product. Thank you Iron Master!

    Heavy (pun intended) duty
    Kevin | July 11th, 2022
    The very first thing you notice is the quality of materials used. Everything is clean, undamaged (very well packed), and clearly durable (chrome plating looks of high quality with powder coated weights). I haven't really banged em around much yet but I'm hoping I'm right when I say that I can see these withstanding the test of time and frequent use. Other products may change weight faster (comparable to changing weights on a barbell, with only 5lb plates available), but not with the availability of the additional weight (of the add-ons) my only complaint is that the pack of hardware to assemble the stand was missing the screws for the top platform but ironmaster was quick to respond to my email and send some out. Great customer service and quality product.

    Excellent quality and shipped/packaged well
    Kp (Texas) | June 30th, 2022
    I began my search for adjustable dumbbells with a similarly priced competitive "selectable" dumbbell product - both dumbbells arrived broken on my doorstep. They were not packaged well and their customer service was disappointingly subpar. I could never imagine hoisting those 80lb "selectable" dumbbells with plastic parts above my head after seeing how easily they broke in transit.

    In contrast, the Ironmaster dumbbells were packaged very well and all parts of my order (dumbbells, stand, kettlebell) arrived in absolutely perfect condition (same carrier as before). This kind of attention to detail from Ironmaster truly communicates what kind of company they are!

    I am very impressed with the build quality of the dumbbells, plates, stand, and kettlebell (and I'm very picky about these things). Everything works exactly as advertised. While it takes a few moments longer to change plates, I find the process to be totally reasonable between sets. The tradeoff for having super solid (no movement) and reliable dumbbells is definitely worth it, and I feel very safe using this product.

    Well done, Ironmaster. Thanks for doing things the right way.
    Well built product
    Eric Albrecht (Oshkosh, wi) | June 24th, 2022
    Very well built and easy to use. I love using these things, very compact too. I think they are easier to hang onto than even a regular dumbell. It's so nice to have 5 to 75lbs adjustable dumbells. They change out fairly quick. These are one of my better purchases.

    Sturdy, great feeling dumbbells

    Dumbbells are much more sturdy than anticipated. Feel secure, and with plenty of handle space. Changing weight is easy and quick. No issues.
    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

    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!

    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.
